The Administration will end the COVID-19 vaccine requirements for international air travelers at the end of the day on May 11, the same day that the COVID-19 public health emergency ends. This means starting May 12, noncitizen nonimmigrant air passengers will no longer need to show proof of being fully vaccinated with an accepted COVID-19 vaccine to board a flight to the United States. CDC’s Amended Order Implementing Presidential Proclamation on Safe Resumption of Global Travel During the COVID-19 Pandemic will no longer be in effect when the Presidential Proclamation Advancing the Safe Resumption of Global Travel During the COVID-19 Pandemic is revoked .

From vaccines to testing: What travelers need to know before the new US travel system on Nov. 8

• The U.S. is launching a new travel system on Nov. 8.
• Vaccinated foreign air travelers will need to show proof of full vaccination and test for COVID-19.
• The new travel system also adds more stringent testing requirements for unvaccinated U.S. travelers.

The United States is about to make it much easier for vaccinated international travelers to visit.  

The White House announced that a new air travel system will take effect Nov. 8, allowing entry for fully vaccinated foreign tourists .  The system is set to launch nearly two years after the U.S. began imposing travel restrictions to prevent the spread of COVID-19 . 

The move by the White House will essentially have the U.S. drop its travel ban on dozens of countries while also making entry more challenging for the unvaccinated. The new system will allow entry for foreign nationals only with vaccinations approved for emergency use by the World Health Organization and would add testing requirements for unvaccinated Americans.

Here’s what we know about the new travel requirements:

What are the entry requirements for foreign nationals?

Starting Nov. 8, non-citizen, non-immigrant air travelers   will need to show proof of full vaccination as well as a pre-departure negative coronavirus test taken within three days of travel before they can board a plane to the U.S. 

Learn more: Best travel insurance

Acceptable forms of proof of vaccination include:

• Digital or paper verifiable record, such as a vaccination certificate or a digital pass with a QR code.  
• Nonverifiable paper record, such as a printout of a COVID-19 vaccination record or COVID-19 vaccination certificate.
• Nonverifiable digital record, such as a digital photo of a vaccination card or record, downloaded vaccine record, downloaded vaccination certificate or a mobile phone application without a QR code.  

The U.S. will accept nucleic acid amplification tests, including PCR tests, and antigen tests. The rules will go into effect for passengers on planes leaving for the U.S. at or after 12:01 a.m. ET on Nov. 8.  

Airlines will collect basic personal contact information   from all U.S.-bound travelers for contact tracing. Airlines are required to keep the information on hand so the Centers for Disease Control and Prevention   can reach out to travelers who may have been infected or exposed to COVID-19.

Masking will be required, but there will be no quarantine mandate for vaccinated travelers or unvaccinated children .

► US  travel bans: How COVID-19 travel restrictions have impacted families and couples

The change will make entering the U.S. possible for travelers from countries now listed on the U.S. travel ban, which prohibits entry for travelers who have been in any of the regions within the past 14 days. The travel ban  took effect in early 2020 and includes :

• United Kingdom
• Republic of Ireland
• South Africa
• The European Schengen area (Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland, Monaco, San Marino and Vatican City)

Currently, the U.S. asks international air passengers only to get tested within three days of their flight to the U.S. and show either the negative test result or proof of recovery  from COVID-19 before boarding. 

What about the land borders with Mexico and Canada?

New travel rules will also take effect for foreign nationals arriving by land or passenger ferry.

Starting Nov. 8, fully vaccinated foreign nationals can cross the land borders for nonessential reasons such as tourism or visiting friends and family . These travelers will need to verbally attest to their reason for travel and vaccination status and be prepared to show proof of vaccination  upon request. U.S. Customs and Border Protection will accept both digital and paper records showing proof of vaccination, including documents not in English.   Foreign nationals will also need appropriate travel documentation to enter the country.  

CBP will spot-check travelers' vaccination documents, and those without documented proof of vaccination can be denied entry. Travelers under 18 will be exempt from the vaccination requirement as long as they are traveling with a fully vaccinated adult, according to Matthew Davies, CBP's executive director of admissibility and passenger programs.  

The new travel rules will go into effect as soon as a port of entry opens on Nov. 8, or at midnight for ports that operate 24 hours a day changes will go into effect at midnight on Nov. 8 for ports that operation 24 hours a day.  

U.S. citizens reentering the country should also bring a Western Hemisphere Travel Initiative document, such as a valid passport, trusted traveler program card, enhanced driver's license or enhanced tribal card. 

Entry rules along the border will change again in early January, with all travelers – including those traveling for essential purposes – required to show proof of full vaccination.

Which vaccines does the US accept for travel?

The CDC has announced that vaccines approved for emergency use by the U.S. Food and Drug Administration and World Health Organization will be accepted for air travel. White House officials expect the CDC to approve the same vaccines for travelers entering the U.S. by land or ferry.  

The FDA has authorized three COVID-19 vaccines for emergency use during the pandemic: Moderna, Johnson & Johnson and Pfizer-BioNTech, the last of which has received the FDA's full stamp of approval.

Vaccines with WHO approval for emergency use include:

• Johnson & Johnson
• Pfizer-BioNTech
• Oxford-AstraZeneca/Covishield 

The CDC confirmed that it would accept a mix-and-match approach to vaccinations. Travelers who have any combination of FDA- or WHO-approved vaccines will be considered fully vaccinated.

The new travel policy does not accept foreign travelers who have had COVID and received just one shot in a two-dose series. White House press secretary Jen Psaki said Tuesday that the administration will "continue to review" its entry requirements.  

► Covaxin gets WHO emergency approval: Travelers vaccinated with Covaxin can enter US   

► 'You feel lonely and left out': These fully vaccinated travelers want to visit the US. They may not be allowed in.

How do the new rules affect kids? 

Foreign nationals under 18 are exempt from the vaccination requirement. Children under two will not need to take a pre-departure COVID test.

Kids 2 and older traveling with a fully vaccinated adult can test three days prior to departure, while children traveling alone or with unvaccinated adults will need to get tested within one day of departure. 

Currently, all air passengers 2 or older, including U.S. citizens and permanent residents, need to show a negative coronavirus test to fly to the U.S.

What are the entry requirements for Americans?

The new travel system adds more stringent testing requirements for unvaccinated U.S. travelers.

Starting Nov. 8, unvaccinated U.S. citizens and permanent residents will need to take a test one day before departure and test again upon arrival in the U.S. 

► New travel rules: What US travelers need to know about the new COVID rules for international flights

Entry requirements will not change for vaccinated Americans. They will still need to show proof of a negative coronavirus test taken no more than three days before departure. 

Americans will not need to be fully vaccinated to board international flights to the U.S.

Are there any exemptions?

There is a limited set of travelers who are exempt from the vaccine requirement for entry.

Children under 18, certain COVID-19 vaccine clinical trial participants and travelers with adverse reactions to the vaccines – such as people who have had severe anaphylactic allergic reactions to a prior COVID-19 vaccine –  will be exempt.

People traveling on non-tourist visas from countries with less than 10% of its population vaccinated who need to enter the U.S. for emergency or humanitarian reasons are also exempt from the vaccine requirement. There are about 50 countries considered to have low vaccine availability at this time.

These exempt travelers will generally need to show that they will comply with public health mandates, including a requirement to be vaccinated in the U.S. if they plan to stay more than 60 days.  

Unless they have recovered from COVID-19 within the last 90 days, unvaccinated travelers  must agree to be tested with a COVID-19 viral test three to five days after their arrival and quarantine for seven days, even if their post-arrival test comes back negative. 

Unvaccinated travelers who are not U.S. citizens or permanent residents must also agree to self-isolate if their post-arrival test is positive or if they develop COVID-19 symptoms. 

Unvaccinated children under 18 will not need to quarantine but will still need to take a post-arrival test. 

► Who is exempt?: These select groups of unvaccinated foreign travelers can enter the US

The CDC will not give exemptions  to people who object to the vaccinations due to religious or moral convictions. 

There will also be testing accommodations for travelers who can prove they recently recovered from the coronavirus. These travelers will need to show a positive COVID-19 viral test result on a sample taken no more than 90 days before their flight's departure and a letter from a licensed healthcare provider or public health official saying they are cleared for travel.

U.S. to ease Covid travel entry rules, require vaccinations for foreign visitors

WASHINGTON — The Biden administration will require all international travelers coming into the United States to be fully vaccinated and tested for Covid-19 under a new system that will open up air travel to vaccinated foreign nationals from dozens of countries for the first time since the early days of the pandemic.

Starting in early November, foreign nationals will be allowed to fly into the U.S. if they are fully vaccinated and able to show proof of vaccination prior to boarding a U.S.-bound flight, White House Covid coordinator Jeffrey Zients said.

The requirement will ease travel restrictions that limited entry into the U.S. in many cases for noncitizens who had recently been in 33 countries , including many European nations and the United Kingdom, regardless of vaccination status. But for travelers outside of those countries, the new system will put stricter requirements in place that could be a barrier to those living in countries where vaccines are in short supply.

"We will move to this much stricter global system, so we will have a consistent approach across all countries, it will require foreign nationals to be vaccinated, to prove they're vaccinated, and then to go through the testing and contact tracing regiments," Zients said.

The U.S. will also start putting into place additional testing requirements, he said. Foreign nationals will have to be tested three days prior to departure to the U.S. and show proof of a negative test, and unvaccinated Americans will have to test within one day of departure and be required to test again after their arrival.

The CDC will also require airlines to collect information for each U.S.-bound traveler, including their phone number and email address, to aid public health officials in contact tracing.

While there is still no vaccination requirement for domestic air travel, Zients said nothing is off the table.

"We clearly have a track record that shows we're pulling available levers to acquire vaccinations and we're not taking any measures off the table on specific authorities used for implementation," he said.

Zients didn't detail what vaccines will qualify and what would constitute as fully vaccinated and said the Centers for Disease Control and Prevention would provide further details. The new policy applies only to air travel and not land border crossings, which have been closed to nonessential travel between Canada and Mexico.

Executive Order on Promoting COVID- ⁠ 19 Safety in Domestic and International   Travel

By the authority vested in me as President by the Constitution and the laws of the United States of America, it is hereby ordered as follows: 

Section 1.  Policy.  Science-based public health measures are critical to preventing the spread of coronavirus disease 2019 (COVID-19) by travelers within the United States and those who enter the country from abroad.  The Centers for Disease Control and Prevention (CDC), the Surgeon General, and the National Institutes of Health have concluded that mask-wearing, physical distancing, appropriate ventilation, and timely testing can mitigate the risk of travelers spreading COVID-19.  Accordingly, to save lives and allow all Americans, including the millions of people employed in the transportation industry, to travel and work safely, it is the policy of my Administration to implement these public health measures consistent with CDC guidelines on public modes of transportation and at ports of entry to the United States.   

Sec. 2.  Immediate Action to Require Mask-Wearing on Certain Domestic Modes of Transportation.

(a)  Mask Requirement.   The Secretary of Labor, the Secretary of Health and Human Services (HHS), the Secretary of Transportation (including through the Administrator of the Federal Aviation Administration (FAA)), the Secretary of Homeland Security (including through the Administrator of the Transportation Security Administration (TSA) and the Commandant of the United States Coast Guard), and the heads of any other executive departments and agencies (agencies) that have relevant regulatory authority (heads of agencies) shall immediately take action, to the extent appropriate and consistent with applicable law, to require masks to be worn in compliance with CDC guidelines in or on: 

(i)    airports; 

(ii)   commercial aircraft; 

(iii)  trains; 

(iv)   public maritime vessels, including ferries; 

(v)    intercity bus services; and

(vi)   all forms of public transportation as defined in section 5302 of title 49, United States Code.

(b)  Consultation.   In implementing this section, the heads of agencies shall consult, as appropriate, with interested parties, including State, local, Tribal, and territorial officials; industry and union representatives from the transportation sector; and consumer representatives.

(c)  Exceptions.   The heads of agencies may make categorical or case-by-case exceptions to policies developed under this section, consistent with applicable law, to the extent that doing so is necessary or required by law.  If the heads of agencies do make exceptions, they shall require alternative and appropriate safeguards, and shall document all exceptions in writing.

(d)  Preemption.  To the extent permitted by applicable law, the heads of agencies shall ensure that any action taken to implement this section does not preempt State, local, Tribal, and territorial laws or rules imposing public health measures that are more protective of public health than those required by the heads of agencies. 

(e)  Coordination.  The Coordinator of the COVID-19 Response and Counselor to the President (COVID-19 Response Coordinator) shall coordinate the implementation of this section.  The heads of agencies shall update the COVID-19 Response Coordinator on their progress in implementing this section, including any categorical exceptions established under subsection (c) of this section, within 7 days of the date of this order and regularly thereafter.  The heads of agencies are encouraged to bring to the attention of the COVID-19 Response Coordinator any questions regarding the scope or implementation of this section.

Sec. 3.  Action to Implement Additional Public Health Measures for Domestic Travel. 

(a)  Recommendations.   The Secretary of Transportation (including through the Administrator of the FAA) and the Secretary of Homeland Security (including through the Administrator of the TSA and the Commandant of the Coast Guard), in consultation with the Director of CDC, shall promptly provide to the COVID-19 Response Coordinator recommendations concerning how their respective agencies may impose additional public health measures for domestic travel.

(b)  Consultation.   In implementing this section, the Secretary of Transportation and the Secretary of Homeland Security shall engage with interested parties, including State, local, Tribal, and territorial officials; industry and union representatives from the transportation sector; and consumer representatives.  

Sec. 4.  Support for State, Local, Tribal, and Territorial Authorities.  The COVID-19 Response Coordinator, in coordination with the Secretary of Transportation and the heads of any other relevant agencies, shall promptly identify and inform agencies of options to incentivize, support, and encourage widespread mask-wearing and physical distancing on public modes of transportation, consistent with CDC guidelines and applicable law.

Sec. 5.  International Travel. 

(a)  Policy.   It is the policy of my Administration that, to the extent feasible, travelers seeking to enter the United States from a foreign country shall be: 

(i)   required to produce proof of a recent negative COVID-19 test prior to entry; and 

(ii)  required to comply with other applicable CDC guidelines concerning international travel, including recommended periods of self-quarantine or self-isolation after entry into the United States.

(b)  Air Travel.  

(i)    The Secretary of HHS, including through the Director of CDC, and in coordination with the Secretary of Transportation (including through the Administrator of the FAA) and the Secretary of Homeland Security (including through the Administrator of the TSA), shall, within 14 days of the date of this order, assess the CDC order of January 12, 2021, regarding the requirement of a negative COVID-19 test result for airline passengers traveling into the United States, in light of subsection (a) of this section.  Based on such assessment, the Secretary of HHS and the Secretary of Homeland Security shall take any further appropriate regulatory action, to the extent feasible and consistent with CDC guidelines and applicable law.  Such assessment and regulatory action shall include consideration of: 

(A)  the timing and types of COVID-19 tests that should satisfy the negative test requirement, including consideration of additional testing immediately prior to departure; (B)  the proof of test results that travelers should be required to provide; (C)  the feasibility of implementing alternative and sufficiently protective public health measures, such as testing, self-quarantine, and self-isolation on arrival, for travelers entering the United States from countries where COVID-19 tests are inaccessible, particularly where such inaccessibility of tests would affect the ability of United States citizens and lawful permanent residents to return to the United States; and (D)  measures to prevent fraud.

(ii)   The Secretary of HHS, in coordination with the Secretary of Transportation (including through the Administrator of the FAA) and the Secretary of Homeland Security (including through the Administrator of the TSA), shall promptly provide to the President, through the COVID-19 Response Coordinator, a plan for how the Secretary and other Federal Government actors could implement the policy stated in subsection (a) of this section with respect to CDC-recommended periods of self-quarantine or self-isolation after a flight to the United States from a foreign country, as he deems appropriate and consistent with applicable law.  The plan shall identify agencies’ tools and mechanisms to assist travelers in complying with such policy.

(iii)  The Secretary of State, in consultation with the Secretary of HHS (including through the Director of CDC), the Secretary of Transportation (including through the Administrator of the FAA), and the Secretary of Homeland Security, shall seek to consult with foreign governments, the World Health Organization, the International Civil Aviation Organization, the International Air Transport Association, and any other relevant stakeholders to establish guidelines for public health measures associated with safe international travel, including on aircraft and at ports of entry.  Any such guidelines should address quarantine, testing, COVID-19 vaccination, follow-up testing and symptom-monitoring, air filtration requirements, environmental decontamination standards, and contact tracing.  

(c)  Land Travel.  The Secretary of State, in consultation with the Secretary of HHS, the Secretary of Transportation, the Secretary of Homeland Security, and the Director of CDC, shall immediately commence diplomatic outreach to the governments of Canada and Mexico regarding public health protocols for land ports of entry.  Based on this diplomatic engagement, within 14 days of the date of this order, the Secretary of HHS (including through the Director of CDC), the Secretary of Transportation, and the Secretary of Homeland Security shall submit to the President a plan to implement appropriate public health measures at land ports of entry.  The plan should implement CDC guidelines, consistent with applicable law, and take into account the operational considerations relevant to the different populations who enter the United States by land.

(d)  Sea Travel.  The Secretary of Homeland Security, through the Commandant of the Coast Guard and in consultation with the Secretary of HHS and the Director of CDC, shall, within 14 days of the date of this order, submit to the President a plan to implement appropriate public health measures at sea ports.  The plan should implement CDC guidelines, consistent with applicable law, and take into account operational considerations.  

(e)  International Certificates of Vaccination or Prophylaxis.  Consistent with applicable law, the Secretary of State, the Secretary of HHS, and the Secretary of Homeland Security (including through the Administrator of the TSA), in coordination with any relevant international organizations, shall assess the feasibility of linking COVID-19 vaccination to International Certificates of Vaccination or Prophylaxis (ICVP) and producing electronic versions of ICVPs.  

(f)  Coordination.  The COVID-19 Response Coordinator, in consultation with the Assistant to the President for National Security Affairs and the Assistant to the President for Domestic Policy, shall coordinate the implementation of this section.  The Secretary of State, the Secretary of HHS, the Secretary of Transportation, and the Secretary of Homeland Security shall update the COVID-19 Response Coordinator on their progress in implementing this section within 7 days of the date of this order and regularly thereafter.  The heads of all agencies are encouraged to bring to the attention of the COVID-19 Response Coordinator any questions regarding the scope or implementation of this section.

Sec. 6.  General Provisions.   (a)  Nothing in this order shall be construed to impair or otherwise affect:

(i)   the authority granted by law to an executive department or agency, or the head thereof; or

(ii)  the functions of the Director of the Office of Management and Budget relating to budgetary, administrative, or legislative proposals.

(b)  This order shall be implemented consistent with applicable law and subject to the availability of appropriations.

(c)  This order is not intended to, and does not, create any right or benefit, substantive or procedural, enforceable at law or in equity by any party against the United States, its departments, agencies, or entities, its officers, employees, or agents, or any other person.

Need travel vaccines? Plan ahead.

International travel increases your chances of getting and spreading diseases that are rare or not found in United States. Find out which travel vaccines you may need to help you stay healthy on your trip.

Before Travel

Make sure you are up to date on all of your routine vaccines . Routine vaccinations protect you from infectious diseases such as measles that can spread quickly in groups of unvaccinated people. Many diseases prevented by routine vaccination are not common in the United States but are still common in other countries.

Check CDC’s destination pages for travel health information . Check CDC’s webpage for your destination to see what vaccines or medicines you may need and what diseases or health risks are a concern at your destination.

Make an appointment with your healthcare provider or a travel health specialist  that takes place at least one month before you leave. They can help you get destination-specific vaccines, medicines, and information. Discussing your health concerns, itinerary, and planned activities with your provider allows them to give more specific advice and recommendations.

Because some vaccines require multiple doses, it’s best to see your health care provider as soon as possible.

Medicines to prevent malaria are pills that you start to take before travel. Take recommended medicines as directed. If your health care provider prescribes medicine for you, take the medicine as directed before, during, and after travel. 

Where can I get travel vaccines?

You may be able to get some travel vaccines from your primary healthcare provider. If you or your healthcare provider need help finding a location that provides certain vaccines or medicines, visit CDC’s Find a Clinic page.

If yellow fever vaccine is recommended or required for your destination, you’ll need to go to a vaccine center authorized to give yellow fever vaccinations. Many yellow fever vaccine centers also provide other pre-travel health care services. Find an  authorized US yellow fever vaccine center .

Examples of Vaccines

Here is a list of possible vaccines that you may need to get for the first time or boosters before you travel.

• Cholera 
• Flu (Influenza)
• Hepatitis A   
• Hepatitis B   
• Japanese encephalitis   
• MMR (Measles, Mumps, Rubella)
• Meningococcal   
• Pneumococcal   
• Polio   
• Rabies   
• Tdap (Tetanus, Diphtheria, Pertussis)
• Typhoid   
• Yellow fever

I’m a U.S. Citizen. Where in the World Can I Go?

For Americans eager to resume international travel, here are the countries that currently allow U.S. citizens to enter, though there may be restrictions, including vaccine requirements.

By Paige McClanahan

This list is no longer being updated. Find the latest coronavirus updates here .

Most of the world’s countries are open to travelers from the United States, and many nations are easing their requirements for visitors to test or quarantine. Some countries that had fully closed to foreign tourists — including Israel, Morocco, Bhutan, Australia and New Zealand — have now reopened to U.S. visitors, although they may continue to impose testing, vaccination or quarantine requirements.

In Europe, a growing number of nations — including Germany, Greece, Italy, Ireland, Switzerland and the United Kingdom, among many others — have eliminated their Covid-related travel restrictions for the summer travel season. Meanwhile, several Southeast Asian nations that had closed their borders to tourists have now reopened. Laos, Thailand, Vietnam, Indonesia, Malaysia, Myanmar and Cambodia are once again welcoming American visitors, although vaccine or testing requirements are in force in most cases.

For its part, the United States has lifted the requirement that inbound passengers, including returning Americans, provide a negative test result taken within one day of departure. The decision to lift the test requirement will be re-evaluated in September; the rule could be reinstated if authorities deem it necessary.

The Centers for Disease Control and Prevention, meanwhile, continues advising Americans not to travel internationally until they are fully inoculated against Covid-19.

Those wanting to learn about the coronavirus risk in a specific country can visit the C.D.C. website where a four-tier ranking system provides guidance. The agency reserves the highest “Level 4” ranking for countries with “special circumstances” that include spiking case numbers, the emergence of worrying variants, or threats to the viability of health care infrastructure. (Levels 1 to 3 are still based primarily on Covid-19 case counts.) At the moment, no countries are classified at Level 4; those at Level 3, which have a “high” incidence of Covid-19, are indicated in the list below. For information on entry requirements like testing and quarantine, as well as curfews and movement restrictions, the State Department’s website offers detailed information by country.

What follows is a list of countries that are open to tourists from the United States. Many require visitors to complete a health form, provide proof of vaccination, and present a recent negative Covid-19 test result. To qualify as fully vaccinated in places such as France, Spain and the Netherlands, a visitor must have received either a booster shot or a second dose within a specified period.

As of May 1, visitors are no longer required to provide a negative test result or proof of vaccination. The C.D.C. risk assessment for Covid-19 is Level 3: High.

Travel to Andorra is over land from Spain or France, so check the entry requirements for those countries first. There are no limits on movement between Spain and Andorra, nor for travelers entering Andorra from France. Travelers 12 and over departing Andorra for France must provide proof of full vaccination, a certificate of recent recovery, or a negative antigen test result from the previous 24 hours. The C.D.C. risk assessment for Covid-19 is Level 3: High.

Visitors must complete a registration form before travel. They must also present a negative result from an R.T.-P.C.R. test administered no more than 72 hours before departure and pay about $20 on arrival to undergo a rapid antigen test at the airport. The C.D.C. risk assessment for Covid-19 is “Level Unknown”; the agency recommends that those who are unvaccinated avoid travel to Angola.

All adult visitors must be vaccinated. Arriving passengers must also carry a negative result from a Covid-19 test. The result may be either from a rapid test taken within two days of arrival, or from an R.T.-P.C.R. test, N.A.A.T. test, or other molecular test administered within three days of arrival. Visitors who completed their primary course of vaccination more than six months previously and who have not received a booster are also required to test on arrival, at their own expense. Guests staying for more than eight days may undergo a free test on day 4 of their visit. The C.D.C. risk assessment for Covid-19 is Level 3: High.

ANTIGUA and BARBUDA

Vaccinated travelers are no longer required to test before travel, provided they are asymptomatic. Unvaccinated visitors must present either a negative result from a P.C.R. test conducted no more than three days before arrival, or a negative result from an antigen test from the previous 24 hours; they must also be without symptoms.

Fact Sheet: Guidance for Travelers to Enter the U.S. at Land Ports of Entry and Ferry Terminals

Updated Date: May 1, 2023

DHS Statement on the Lifting of Title 19 Requirements

Beginning May 12, 2023, DHS will no longer require non-U.S. travelers entering the United States via land ports of entry and ferry terminals to be fully vaccinated against COVID-19 and provide related proof of vaccination upon request. DHS intends to rescind these Title 19 travel restrictions in alignment with the end of the Public Health Emergency and the termination of the Presidential Proclamation on air travel .

Updated Date: April 21, 2022

As of Thursday, April 21, 2022, DHS will extend COVID-19-related land border entry requirements. Non-U.S. travelers seeking to enter the United States via land ports of entry and ferry terminals at the U.S.-Mexico and U.S.-Canada borders are required to be fully vaccinated against COVID-19 and provide proof of vaccination upon request.  

These restrictions apply to non-U.S. travelers who are traveling for essential or non-essential reasons. They do not apply to U.S. citizens, Lawful Permanent Residents, or U.S. nationals. 

This announcement does not affect requirements for entry into the United States by air.

What To Expect

As travel returns to pre-pandemic levels, wait times are expected to increase. The resources below are intended to prepare travelers to improve the cross-border travel experience. Travelers should plan for longer than normal wait times and longer lines at U.S. land border crossings when planning their trip and are reminded to exercise patience.

To help reduce wait times and long lines, travelers arriving or departing from air, sea or land ports of entry are encouraged to opt in to using Simplified Arrival or Mobile Passport Control , which can make the inspection process touchless and more expedient with the use of facial comparison technology . Documented non-citizens may also apply for and manage their I-94s through the CBP One TM mobile application, which serves as a single portal for individuals to access CBP mobile applications and services.

Arrival at Land Port of Entry or Ferry Terminal

Since January 22, 2022, DHS has allowed inbound non-U.S. travelers (non-U.S. citizens who are neither U.S. nationals nor lawful permanent residents) to seek to enter the United States via a land port of entry (POE) or ferry terminal if they are fully vaccinated and have appropriate documentation.

Non-U.S. individuals traveling to the United States via land ports of entry or ferry terminals, whether for essential or non-essential reasons, must: 

• verbally attest to their COVID-19 vaccination status;
• provide, upon request, proof of a CDC-approved COVID-19 vaccination, as outlined on the CDC website ;  
• present a valid  Western Hemisphere Travel Initiative  (WHTI)-compliant document, such as a valid passport, Trusted Traveler Program Card, or Enhanced Tribal Card;   
• be prepared to present any other relevant documents requested by a U.S. Customs and Border Protection (CBP) officer during a border inspection; and   

COVID-19 testing is not required for entry via a land or ferry port of entry.

In March 2020, to prevent the further spread of COVID-19, the U.S. government issued restrictions on travel into the United States. DHS implemented temporary restrictions, limiting entry at the U.S. northern and southern land borders to persons engaged in essential travel, including lawful trade, emergency response, and public health purposes. The White House also suspended entry to foreign nationals who had recently been in certain countries.

In October 2021, the White House  announced  that, starting November 8, 2021, the U.S. government would move away from the country-by-country restrictions previously applied during the COVID-19 pandemic and adopt travel policies that rely primarily on vaccination to advance the safe resumption of travel. Since January 22, 2022, DHS has imposed a vaccination requirement on non-U.S. individuals seeking to cross into the United States at land ports of entry or ferry terminals.

COVID-19, also called coronavirus disease 2019, is an illness caused by a virus. The virus is called severe acute respiratory syndrome coronavirus 2, or more commonly, SARS-CoV-2. It started spreading at the end of 2019 and became a pandemic disease in 2020.

• Coronavirus

Coronaviruses are a family of viruses. These viruses cause illnesses such as the common cold, severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS) and coronavirus disease 2019 (COVID-19).

The virus that causes COVID-19 spreads most commonly through the air in tiny droplets of fluid between people in close contact. Many people with COVID-19 have no symptoms or mild illness. But for older adults and people with certain medical conditions, COVID-19 can lead to the need for care in the hospital or death.

Staying up to date on your COVID-19 vaccine helps prevent serious illness, the need for hospital care due to COVID-19 and death from COVID-19 . Other ways that may help prevent the spread of this coronavirus includes good indoor air flow, physical distancing, wearing a mask in the right setting and good hygiene.

Medicine can limit the seriousness of the viral infection. Most people recover without long-term effects, but some people have symptoms that continue for months.

Typical COVID-19 symptoms often show up 2 to 14 days after contact with the virus.

Symptoms can include:

• Shortness of breath.
• Loss of taste or smell.
• Extreme tiredness, called fatigue.
• Digestive symptoms such as upset stomach, vomiting or loose stools, called diarrhea.
• Pain, such as headaches and body or muscle aches.
• Fever or chills.
• Cold-like symptoms such as congestion, runny nose or sore throat.

People may only have a few symptoms or none. People who have no symptoms but test positive for COVID-19 are called asymptomatic. For example, many children who test positive don't have symptoms of COVID-19 illness. People who go on to have symptoms are considered presymptomatic. Both groups can still spread COVID-19 to others.

Some people may have symptoms that get worse about 7 to 14 days after symptoms start.

Most people with COVID-19 have mild to moderate symptoms. But COVID-19 can cause serious medical complications and lead to death. Older adults or people who already have medical conditions are at greater risk of serious illness.

COVID-19 may be a mild, moderate, severe or critical illness.

• In broad terms, mild COVID-19 doesn't affect the ability of the lungs to get oxygen to the body.
• In moderate COVID-19 illness, the lungs also work properly but there are signs that the infection is deep in the lungs.
• Severe COVID-19 means that the lungs don't work correctly, and the person needs oxygen and other medical help in the hospital.
• Critical COVID-19 illness means the lung and breathing system, called the respiratory system, has failed and there is damage throughout the body.

Rarely, people who catch the coronavirus can develop a group of symptoms linked to inflamed organs or tissues. The illness is called multisystem inflammatory syndrome. When children have this illness, it is called multisystem inflammatory syndrome in children, shortened to MIS -C. In adults, the name is MIS -A.

When to see a doctor

Contact a healthcare professional if you test positive for COVID-19 . If you have symptoms and need to test for COVID-19 , or you've been exposed to someone with COVID-19 , a healthcare professional can help.

People who are at high risk of serious illness may get medicine to block the spread of the COVID-19 virus in the body. Or your healthcare team may plan regular checks to monitor your health.

Get emergency help right away for any of these symptoms:

• Can't catch your breath or have problems breathing.
• Skin, lips or nail beds that are pale, gray or blue.
• New confusion.
• Trouble staying awake or waking up.
• Chest pain or pressure that is constant.

This list doesn't include every emergency symptom. If you or a person you're taking care of has symptoms that worry you, get help. Let the healthcare team know about a positive test for COVID-19 or symptoms of the illness.

COVID-19 is caused by infection with the severe acute respiratory syndrome coronavirus 2, also called SARS-CoV-2.

The coronavirus spreads mainly from person to person, even from someone who is infected but has no symptoms. When people with COVID-19 cough, sneeze, breathe, sing or talk, their breath may be infected with the COVID-19 virus.

The coronavirus carried by a person's breath can land directly on the face of a nearby person, after a sneeze or cough, for example. The droplets or particles the infected person breathes out could possibly be breathed in by other people if they are close together or in areas with low air flow. And a person may touch a surface that has respiratory droplets and then touch their face with hands that have the coronavirus on them.

It's possible to get COVID-19 more than once.

• Over time, the body's defense against the COVID-19 virus can fade.
• A person may be exposed to so much of the virus that it breaks through their immune defense.
• As a virus infects a group of people, the virus copies itself. During this process, the genetic code can randomly change in each copy. The changes are called mutations. If the coronavirus that causes COVID-19 changes in ways that make previous infections or vaccination less effective at preventing infection, people can get sick again.

The virus that causes COVID-19 can infect some pets. Cats, dogs, hamsters and ferrets have caught this coronavirus and had symptoms. It's rare for a person to get COVID-19 from a pet.

Risk factors

The main risk factors for COVID-19 are:

• If someone you live with has COVID-19 .
• If you spend time in places with poor air flow and a higher number of people when the virus is spreading.
• If you spend more than 30 minutes in close contact with someone who has COVID-19 .

Many factors affect your risk of catching the virus that causes COVID-19 . How long you are in contact, if the space has good air flow and your activities all affect the risk. Also, if you or others wear masks, if someone has COVID-19 symptoms and how close you are affects your risk. Close contact includes sitting and talking next to one another, for example, or sharing a car or bedroom.

It seems to be rare for people to catch the virus that causes COVID-19 from an infected surface. While the virus is shed in waste, called stool, COVID-19 infection from places such as a public bathroom is not common.

Serious COVID-19 illness risk factors

Some people are at a higher risk of serious COVID-19 illness than others. This includes people age 65 and older as well as babies younger than 6 months. Those age groups have the highest risk of needing hospital care for COVID-19 .

Not every risk factor for serious COVID-19 illness is known. People of all ages who have no other medical issues have needed hospital care for COVID-19 .

Known risk factors for serious illness include people who have not gotten a COVID-19 vaccine. Serious illness also is a higher risk for people who have:

• Sickle cell disease or thalassemia.
• Serious heart diseases and possibly high blood pressure.
• Chronic kidney, liver or lung diseases.

People with dementia or Alzheimer's also are at higher risk, as are people with brain and nervous system conditions such as stroke. Smoking increases the risk of serious COVID-19 illness. And people with a body mass index in the overweight category or obese category may have a higher risk as well.

Other medical conditions that may raise the risk of serious illness from COVID-19 include:

• Cancer or a history of cancer.
• Type 1 or type 2 diabetes.
• Weakened immune system from solid organ transplants or bone marrow transplants, some medicines, or HIV .

This list is not complete. Factors linked to a health issue may raise the risk of serious COVID-19 illness too. Examples are a medical condition where people live in a group home, or lack of access to medical care. Also, people with more than one health issue, or people of older age who also have health issues have a higher chance of severe illness.

Complications

Complications of COVID-19 include long-term loss of taste and smell, skin rashes, and sores. The illness can cause trouble breathing or pneumonia. Medical issues a person already manages may get worse.

Complications of severe COVID-19 illness can include:

• Acute respiratory distress syndrome, when the body's organs do not get enough oxygen.
• Shock caused by the infection or heart problems.
• Overreaction of the immune system, called the inflammatory response.
• Blood clots.
• Kidney injury.

Post-COVID-19 syndrome

After a COVID-19 infection, some people report that symptoms continue for months, or they develop new symptoms. This syndrome has often been called long COVID, or post- COVID-19 . You might hear it called long haul COVID-19 , post-COVID conditions or PASC. That's short for post-acute sequelae of SARS -CoV-2.

Other infections, such as the flu and polio, can lead to long-term illness. But the virus that causes COVID-19 has only been studied since it began to spread in 2019. So, research into the specific effects of long-term COVID-19 symptoms continues.

Researchers do think that post- COVID-19 syndrome can happen after an illness of any severity.

Getting a COVID-19 vaccine may help prevent post- COVID-19 syndrome.

• Long-term effects of COVID-19

The Centers for Disease Control and Prevention (CDC) recommends a COVID-19 vaccine for everyone age 6 months and older. The COVID-19 vaccine can lower the risk of death or serious illness caused by COVID-19.

The COVID-19 vaccines available in the United States are:

2023-2024 Pfizer-BioNTech COVID-19 vaccine. This vaccine is available for people age 6 months and older.

Among people with a typical immune system:

• Children age 6 months up to age 4 years are up to date after three doses of a Pfizer-BioNTech COVID-19 vaccine.
• People age 5 and older are up to date after one Pfizer-BioNTech COVID-19 vaccine.
• For people who have not had a 2023-2024 COVID-19 vaccination, the CDC recommends getting an additional shot of that updated vaccine.

2023-2024 Moderna COVID-19 vaccine. This vaccine is available for people age 6 months and older.

• Children ages 6 months up to age 4 are up to date if they've had two doses of a Moderna COVID-19 vaccine.
• People age 5 and older are up to date with one Moderna COVID-19 vaccine.

2023-2024 Novavax COVID-19 vaccine. This vaccine is available for people age 12 years and older.

• People age 12 years and older are up to date if they've had two doses of a Novavax COVID-19 vaccine.

In general, people age 5 and older with typical immune systems can get any vaccine approved or authorized for their age. They usually don't need to get the same vaccine each time.

Some people should get all their vaccine doses from the same vaccine maker, including:

• Children ages 6 months to 4 years.
• People age 5 years and older with weakened immune systems.
• People age 12 and older who have had one shot of the Novavax vaccine should get the second Novavax shot in the two-dose series.

Talk to your healthcare professional if you have any questions about the vaccines for you or your child. Your healthcare team can help you if:

• The vaccine you or your child got earlier isn't available.
• You don't know which vaccine you or your child received.
• You or your child started a vaccine series but couldn't finish it due to side effects.

People with weakened immune systems

Your healthcare team may suggest added doses of COVID-19 vaccine if you have a moderately or seriously weakened immune system. The FDA has also authorized the monoclonal antibody pemivibart (Pemgarda) to prevent COVID-19 in some people with weakened immune systems.

Control the spread of infection

In addition to vaccination, there are other ways to stop the spread of the virus that causes COVID-19 .

If you are at a higher risk of serious illness, talk to your healthcare professional about how best to protect yourself. Know what to do if you get sick so you can quickly start treatment.

If you feel ill or have COVID-19 , stay home and away from others, including pets, if possible. Avoid sharing household items such as dishes or towels if you're sick.

In general, make it a habit to:

• Test for COVID-19 . If you have symptoms of COVID-19 test for the infection. Or test five days after you came in contact with the virus.
• Help from afar. Avoid close contact with anyone who is sick or has symptoms, if possible.
• Wash your hands. Wash your hands well and often with soap and water for at least 20 seconds. Or use an alcohol-based hand sanitizer with at least 60% alcohol.
• Cover your coughs and sneezes. Cough or sneeze into a tissue or your elbow. Then wash your hands.
• Clean and disinfect high-touch surfaces. For example, clean doorknobs, light switches, electronics and counters regularly.

Try to spread out in crowded public areas, especially in places with poor airflow. This is important if you have a higher risk of serious illness.

The CDC recommends that people wear a mask in indoor public spaces if you're in an area with a high number of people with COVID-19 in the hospital. They suggest wearing the most protective mask possible that you'll wear regularly, that fits well and is comfortable.

Travel and COVID-19

Travel brings people together from areas where illnesses may be at higher levels. Masks can help slow the spread of respiratory diseases in general, including COVID-19 . Masks help the most in places with low air flow and where you are in close contact with other people. Also, masks can help if the places you travel to or through have a high level of illness.

Masking is especially important if you or a companion have a high risk of serious illness from COVID-19 .

Protect yourself and others from Flu, COVID-19, and RSV

Respiratory viruses commonly cause illness such as flu , COVID-19 , and respiratory syncytial virus (RSV) , especially in the fall and winter. There are actions you can take to protect yourself and others. Learn about how to reduce your risk of getting sick from these viruses, and if they are spreading in your community.

• If you are at high risk of getting very sick from COVID-19, talk with a healthcare provider about additional prevention actions.
• If you are at high risk of getting very sick , wear a high-quality mask or respirator (e.g., N95) when indoors in public.
• If you have household or social contact with someone at high risk for getting very sick, consider self-testing to detect infection before contact, and consider wearing a high-quality mask when indoors with them.
• Wear a high-quality mask or respirator .
• If you are at high risk of getting very sick , consider avoiding non-essential indoor activities in public where you could be exposed.
• For most people that means getting a current flu vaccine and a current COVID-19 vaccine . Find a vaccine at vaccines.gov .
• An RSV vaccine given to the mother during pregnancy
• An RSV immunization given to infants and some older babies
• Adults 60 years and older should talk to their healthcare provider about whether a single dose of RSV vaccine is right for them.

Classifications based on data representing the week ending 11/25/23 (Activity Levels, Illness Trends), using data as of 11/29/23 (Illness Trends) and 11/30/23 (Activity Levels).

Overall levels of respiratory illness are determined weekly based on the percentage of visits to emergency departments and primary care clinics for fever and cough or sore throat reported to ILINet ; therefore, a variety of respiratory pathogens that cause similar symptoms may be included. Colors used for levels of respiratory illness were selected to represent the overarching ILINet categories and may not match colors displayed elsewhere.

For illness trends based on visits to emergency departments, trajectory classifications (increasing, stable, or decreasing) are based on a 3-week moving average to smooth week-to-week fluctuations. For example, a jurisdiction could see an increase in the most recent week, but still be classified as “stable” based on trends over the past three weeks. Learn more about respiratory illness data.

As of May 10, 2024, COVID-19 hospitalization level data are no longer included on this page, as, effective May 1, 2024, hospitals are no longer required to report COVID-19 hospital admissions data to HHS through CDC's National Healthcare Safety Network (NHSN). Data voluntarily reported to NHSN after May 1, 2024 will be available starting May 10, 2024 on COVID Data Tracker Hospitalizations and data.cdc.gov .

What to make of the new COVID variants, FLiRT

Ailsa Chang

As much as we would all love to ignore COVID, a new set of variants that scientists call “FLiRT” is here to remind us that the virus is still with us.

The good news: as of last Friday, the CDC says that the amount of respiratory illness in the U.S. is low.

The not-so-great news: the U.S. has often flirted with summer COVID waves because of travel and air-conditioned gatherings.

Dr. Ashish Jha, the dean of the Brown University School of Public Health and former White House COVID-19 response coordinator, returned to All Things Considered to speak with host Ailsa Chang about what the new variants could bring.

This interview has been lightly edited for length and clarity.

Interview highlights

Ailsa Chang: So how concerned would you say scientists are about whether these FLiRT variants come with increased transmissibility or increased disease severity, compared to previous variants?

Ashish Jha: We're seeing exactly what we have expected: The virus continues to evolve to try to escape the wall of immunity we have built up through vaccines and infections. Is this more transmissible? It is. That's why it has become more dominant. But the really important question is, is it going to get people to become more sick than previous versions? And all the evidence right now we have is no. If you have been vaccinated, or you had previous infections – or you’re one of the majority of Americans who have had both – you are likely to have a mild infection and not get particularly sick. Obviously, we have to continue monitoring every new variant, but this is pretty expected.

Chang: Do you expect some sort of summer surge is on the way? And if so, do you have any advice for people who don't want COVID to disrupt their summer plans, even if they get a mild infection?

Jha: Every summer since the beginning of this pandemic, we have seen a summer wave. And therefore, my expectation is we probably will get a summer wave. We spend a lot more time indoors in the summer – especially in the South, where it gets very hot – so we tend to see those waves to be a bit bigger down in the southern parts of the country. When I think about who's at risk of having complications from these infections, it's older Americans. It's immunocompromised Americans. For them, the two big things are: first, making sure they're up to date on their vaccines. Second, if they do get an infection, we have widely available treatments. Obviously, if you're worried about getting infected at all, avoid crowded indoor spaces. You can wear a mask. Those things still work.

How the pandemic gave power to superbugs

Chang: We've now had four and a half years to observe this virus as it has spread. I'm wondering what are some key patterns that you have seen over that time?

Jha: We are seeing pretty typically about two waves a year: one in the summer, one in the winter, all caused by ongoing evolution of the virus. We're seeing the people who are landing in the hospital. There's still a lot of people getting very sick from this. The other thing that's worth thinking about is there's always a chance that this virus could evolve in some very substantial way, so that it could really cause more disruption and more illness. We've got to continue monitoring and paying attention to that. I don't expect that to happen. But if it does, we've got to be ready.

It's Been a Minute

Bumble & the trap of modern dating; plus, living ethically in covid's aftermath.

Chang: In the long run do you think we'll be treating COVID much like we treat other seasonal respiratory illnesses? Like, there will be a new vaccine formulation every fall for expected seasonal surges and this is just what we are going to have to live with for the rest of time?

Jha: Yeah. The way I have thought about this is every year I go and get my flu shot. We have a new formulation. I will probably continue doing that for COVID. So I'm going to have flu and COVID shots. And at some point as I get older, I will probably need an RSV shot every year as well. It's inconvenient. It can be a little bit annoying. But the bottom line is these are life-saving things and people should be doing them.
