U.S. considers airline wastewater testing as Covid surges in China

CNBC

As Covid-19 infections surge in China, the U.S. Centers for Disease Control and Prevention is considering sampling wastewater taken from international aircraft to track any emerging new variants, the agency told Reuters.

Such a policy would offer a better solution to tracking the virus and slowing its entry into the United States than new travel restrictions announced this week by the U.S. and other countries, which require mandatory negative Covid tests for travelers from China, three infectious disease experts told Reuters.
