The U.S. Centers for Disease Control and Prevention is expanding surveillance for infectious diseases at four major airports to track pathogens, including coronavirus and the flu. in 2021 during the coronavirus outbreak to detect new variants of the disease and other infectious pathogens by collecting samples of nasal swabs and wastewater from arriving international travelers. The program is currently operating at six U.S.
The program involves passengers arriving from out of the country and volunteering for a sample to be taken and recorded anonymously. TGS has tested over 370,000 travelers through nasal swab sampling as of October “from over 135 countries from all World Health Organization regions.” “One sample from an aircraft coming from a geographic destination afar can give us information potentially about 200 to 300 people that were on that plane,” said Friedman.
