    Identifying and Tracking New Viral Variants Among International Travelers

    Travelers are an important population to consider when tracking new and emerging infectious diseases. Travelers move from place to place quickly and can get and spread infectious diseases. U.S. airports are visited by more than 1 billion travelers each year and can serve as the front line for public health officials to detect variants of SARS-CoV-2, the virus that causes COVID-19, in arriving international travelers. Learn more about genomic surveillance for SARS-CoV-2.

    The Traveler Genomic Surveillance program (TGS), run by the Travelers’ Health Branch at CDC in partnership with Ginkgo Bioworks and XpresCheck, plays an important role in U.S. national surveillance by testing travelers to detect new variants entering the country and fill gaps in global surveillance.

    In September 2021, during the Delta wave, the program began collecting samples from travelers arriving at three major U.S. international airports, John F. Kennedy in New York City, Newark Liberty, and San Francisco. In November 2021, in response to the emergence of the Omicron variant, TGS quickly scaled up by adding a fourth airport, Hartsfield-Jackson in Atlanta. Between 2022 and early 2023, the program expanded to three additional airports, Los Angeles, Seattle, and Washington, D.C.-Dulles. The program currently targets hundreds of flights per week from select countries representing all WHO regions.
