SUPPLEMENTARY INFORMATION:

This Notice and Order prohibit the introduction into the United States of any aircraft passenger departing from any foreign country unless the passenger: (1) Has a negative pre-departure test result for SARS-CoV-2, the virus that causes COVID-19 (Qualifying Test); or (2) written or electronic documentation of recovery from COVID-19 after previous SARS-CoV-2 infection in the form of a positive viral test result and a letter from a licensed health care provider or public health official stating that the passenger has been cleared for travel (Documentation of Recovery). The negative pre-departure test must be a viral test that was conducted on a specimen collected during the 3 calendar days preceding the flight's departure from a foreign country (Qualifying Test). Alternatively, if the passenger has recovered from COVID-19, the passenger may instead travel with written or electronic documentation of a positive viral test result that confirms previous SARS-CoV-2 infection and a letter from a licensed health care provider or public health official stating that the passenger has been cleared for travel (Documentation of Recovery). A passenger must retain written or electronic documentation reflecting the negative Qualifying Test result or Documentation of Recovery presented to the airline or other aircraft operator. A passenger must also produce such Qualifying Test result or Documentation of Recovery upon request to any U.S. government official or a cooperating state or local public health authority.

This Notice and Order constitute a controlled free pratique to any airline or other aircraft operator with an aircraft arriving into the United States. Pursuant to this controlled free pratique, the airline or other aircraft operator must comply with the following conditions to receive permission for the aircraft to enter and disembark passengers in the United States:

• Airline or other aircraft operator must verify that every passenger—2 years of age or older—onboard the aircraft has attested to receiving a negative Qualifying Test result or to having recovered from COVID-19 after previous SARS-CoV-2 infection and being cleared to travel by a licensed health care provider or public health official.
• Airline or other aircraft operator must confirm that every passenger onboard the aircraft has documentation of a negative Qualifying Test result or Documentation of Recovery from COVID-19.

This Order establishes requirements for (1) airlines arriving into the United States from any foreign country and (2) passengers departing any foreign country with a final destination in the United States.

Background

The COVID-19 pandemic has spread throughout the world. Individuals who travel may be at risk for exposure to SARS-CoV-2 before, during, and after travel. This could result in U.S.-bound travelers further spreading the virus to others during travel, upon arrival in the United States, and at their destinations.

Over the last few weeks, the United Kingdom (UK) has faced a rapid increase in COVID-19 cases in South East England, leading to enhanced epidemiological and virological investigations. On December 14, 2020, Public Health England announced that a new variant of SARS-CoV-2 had been identified across the southeast of England.^[6] Preliminary analysis in the UK suggests that this SARS-CoV-2 variant may be more transmissible than previously circulating variants, with an estimated potential to increase the reproductive number (R₀) by 0.4-0.7 or greater with an estimated increased transmissibility of up to 70 percent.^[7]

On December 19, 2020, in response to the emergence of the UK variant, the countries comprising the UK announced stricter measures to be applied from December 20 and over the coming weeks, with affected areas entering a `Tier 4' level with movement restrictions within and between more and less heavily affected areas. These measures have included recommendations for residents of the most affected areas to restrict movements and travel, including international travel, outside of these areas. The government of Scotland announced a travel ban between Scotland and the rest of the UK. In addition, the Netherlands issued a travel ban from the UK effective through January 1, 2021, and Belgium temporarily halted flight and train travel from the UK. Other countries took similar measures to restrict travel from the UK.

A second new variant of SARS-CoV-2 was reported in the Republic of South Africa (RSA) on December 18, 2020, that also appears to spread more rapidly than earlier variants of the virus. The RSA variant is distinct from the UK variant but shares a mutation in the spike protein that appears to increase transmissibility. Since being identified, the new variant has spread inland from coastal regions of RSA and has become the predominant variant in some areas of the country.

During December 21-26, 2020, several countries implemented restrictions on travel from South Africa, including China, El Salvador, Germany, Guatemala, Israel, Panama, Sudan, Switzerland, Turkey, and the UK. The Netherlands imposed a ban on travel from RSA on December 21 but lifted the ban for both the UK and RSA on December 23, stating that travelers will instead need to present a negative COVID-19 test result obtained within 72 hours of their scheduled arrival in the Netherlands, followed by 10 days of self-quarantine. On December 28, Japan imposed a ban on entry of all foreign nationals through the end of January 2021. On December 28, the Government of South Africa announced new restrictions on businesses and public movement. As of January 7, 2021, Canada requires air passengers 5 years of age or older to test negative for COVID-19 before arrival. On January 8, the United Kingdom announced a pre-departure testing requirement for all inbound international travelers with limited exceptions; a 10-day post-arrival quarantine will still be required.

On December 25, 2020, CDC issued an Order requiring proof of a negative Qualifying Test result for all airline passengers arriving from the UK to the United States. Since then, cases of the UK and RSA variants have been discovered in four Canadian provinces, including in individuals with no travel history indicating spread in Canada. The UK variant has also been found in at least 50 countries and the RSA variant has also been detected in at least 15 countries. The first case of the UK variant in the United States was found in Colorado on December 29, in an individual with no known travel history. On December 30, a second case was reported in California. Since then, the UK variant strain has accounted for 72 cases in 10 U.S. states. Another new variant strain of concern initially detected in South America in March 2020 has been detected in at least 19 countries on 5 continents through late December and has mutations in the spike protein that raise concerns of increased infectivity.

While it is known and expected that viruses constantly change through mutation leading to the emergence of new variants, these new variants have emerged at a time when numbers of new cases in the United States have continued to increase at alarming rates. Additional new virus variants are also likely to emerge as the virus continues to evolve and mutate. Accordingly, further action is needed to help mitigate the spread of these and other new virus variants into the United States.

Based on increased transmissibility and spread of these new variants of SARS-CoV-2, and to reduce introduction and spread of these and future SARS-CoV-2 variants into the United States, expanding current UK pre-departure testing requirements to all foreign countries and U.S.-bound passengers is warranted. This approach to testing-based risk assessment has been addressed in CDC guidance and the Runway to Recovery guidance jointly issued by the Departments of Transportation, Homeland Security, and Health and Human Services.^[8] Testing for SARS-CoV-2 infection is a proactive approach and not dependent on the infecting strain. Approximately 120 countries now use testing in some form to monitor risk and control introduction and spread. With case counts and deaths due to COVID-19 continuing to increase around the globe and the high proportion of infected people with asymptomatic or pre-symptomatic infections, the United States must take a dual approach to combatting the virus. This means concurrently mitigating and slowing the introduction and spread of SARS-CoV-2 and controlling transmission within U.S. communities that are currently being overwhelmed by a surge in infections, hospitalizations, and deaths.

Pre-departure testing may detect travelers infected with SARS-CoV-2 before they initiate their travel. CDC recommends viral testing and receipt of results 1-3 days ^[9] before departure for international travelers, particularly those traveling long distances or passing through transportation hubs such as airports where social distancing may be challenging. CDC modeling indicates that pre-departure testing is most effective when combined with self-monitoring.^[10] Testing before departure results in the greatest reduction of transmission risk during travel when the specimen is collected close to the time of departure. Earlier testing (i.e., more than 3 days before travel) provides little benefit beyond what self-monitoring alone can provide.

For persons previously diagnosed with COVID-19 who remain asymptomatic after recovery, CDC does not recommended retesting within 3 months after the date of symptom onset (or the date of first positive viral diagnostic test if their infection was asymptomatic) for the initial SARS-CoV-2 infection.^[11] Persons who develop any symptoms of COVID-19 during this time period should not travel and seek care for testing and evaluation. This guidance may be updated as additional information about people who have recovered from COVID-19 becomes available.

Pre-departure testing does not eliminate all risk. However, when pre-departure testing is combined with other measures such as self-monitoring for symptoms of COVID-19, wearing masks, social distancing, and hand hygiene, it can make travel safer by reducing spread on conveyances, in transportation hubs, and at destinations. For international air travelers and others with higher risk of exposure, CDC additionally recommends a post-arrival test 3-5 days after arrival at destination, combined with self-monitoring and a 7-day period of staying home (or in a comparable location such as a hotel room) to further reduce the risk of translocating the virus into destination communities.^[12]

As cases of COVID-19 continue to rise across the globe and travel volume increases, routine pre-departure testing of all U.S.-bound aircraft passengers is needed not only to reduce introduction of the two known SARS-CoV-2 variants from UK and RSA, but also future variants that might be more transmissible and cause more severe illness.

Action

For these reasons, I hereby determine that passengers covered by this Order are at risk of transmitting the new SARS-CoV-2 virus variants or other potential variants and that requiring such passengers to demonstrate either negative COVID-19 test results or recovery from COVID-19 after previous SARS-CoV-2 infection is needed as a public health measure to protect the health of fellow travelers and U.S. communities.

Attachment A

Passenger Disclosure and Attestation to the United States of America

All airlines or other aircraft operators covered by the Order must provide the following disclosure to their passengers and collect the attestation prior to embarkation.

Airline and Aircraft Operator Disclosure Requirement

As required by United States federal law, all airlines or other aircraft operators must confirm either a negative COVID-19 test result or recovery from COVID-19 and clearance to travel and collect a passenger attestation on behalf of the U.S. Centers for Disease Control and Prevention (CDC) for certain passengers on aircraft departing from a foreign country and arriving in the United States.

Each individual 2 years of age or older must provide a separate attestation. Unless otherwise permitted by law, a parent or other authorized individual should attest on behalf of a passenger aged 2 to 17 years. An individual may attest on behalf of another passenger for whom the individual is authorized to submit the required information (for example, immediate family member(s), legal guardian, or travel agent), if that person is unable to attest on his or her own behalf (e.g., because of physical or mental impairment).

The information provided must be accurate and complete to the best of the individual's knowledge.

Under United States federal law, each passenger must provide this attestation. Failure to provide this attestation, or submitting false or misleading information, could result in delay of travel, denial of boarding, denial of boarding on future travel, or put the passenger or other individuals at risk of harm, including serious bodily injury or death. Any passenger who fails to comply with these requirements may be subject to criminal penalties under, among others, 42 U.S.C. 271 and 42 CFR 71.2, in conjunction with 18 U.S.C. 3559 and 3571. Willfully providing false or misleading information may lead to criminal fines and imprisonment under, among others, 18 U.S.C. 1001. Providing this information can help protect you, your friends and family, your communities, and the United States. CDC appreciates your cooperation.

Passenger Attestation Requirement

I [name of passenger or authorized representative] have read the disclosure pertaining to my obligation to obtain a negative pre-departure test result for COVID-19 or to having recovered from COVID-19 after previous SARS-CoV-2 infection and being cleared to travel in order to board an aircraft departing from a foreign country and arriving in the United States.
