XpresCheck and Gingko Bioworks, Inc

CDC, XpresCheck, and Ginkgo Bioworks, Inc. are collaborating on an enhanced SARS-CoV-2 surveillance project that involves voluntary testing of arriving international travelers at select US airports. Arriving air passengers are offered pooled testing conducted in the airport and at-home RT-PCR kits for saliva testing 3-5 days after arrival. All positive tests are sequenced, enabling near-real-time detection of novel COVID-19 variant strains among travelers entering the United States.
