It would make more sense to screen a plane's wastewater to look for new variants than to screen individual passenger volunteers, some researchers say. Others say any information is helpful.

The CDC recently expanded the program from five U.S. airports to seven — adding Seattle and Los Angeles because those West Coast hubs receive large numbers of travelers from Asia. The CDC also increased the number of flights being screened at Dulles and the other airports in the program from 300 to 500 each week, enabling the program to now collect samples from more than 4,000 passengers a week, she says.
"I can imagine if I were walking through an airport and I wasn't feeling well and I was asked if I wanted to participate in a COVID surveillance program — even if it were guaranteed that it would be anonymous — I don't think I would be likely to want to participate," says"You can imagine other travelers may want to test themselves privately and know the results before the government does," she says.
