Airport Screeners Are Likely Missing 2 Out of 3 COVID-19 Carriers, Researchers Warn

According to the World Health Organization (WHO), there are now more than 80,000 confirmed cases of COVID-19 worldwide, about 78,000 of them in China. The WHO categorizes the global risk from the virus as high, recognizing the potential for the outbreak to spread further.

One way that governments have been trying to prevent that is via screening travelers at airports, but researchers estimate that those airport screenings won't catch two-thirds of people carrying the SARS-CoV-2 virus. It can take up to 14 days for a person who is infected with the virus to show symptoms of COVID-19, meaning they could travel unnoticed during that incubation period.

Using computer models, researchers from the U.K. and the U.S. have estimated that even under best-case scenarios, airport screeners will miss 53% of cases. The study's lead author, Katelyn Gostic, a postdoctoral fellow at the University of Chicago, says that screenings may not be effective and that "governments should be thinking about pandemic mitigation." The Centers for Disease Control and Prevention is already warning Americans that they should expect the virus to spread across the U.S., and that it could cause significant disruption.
