Description: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.
