China Covid: experts estimate 9,000 deaths a day as US says it may sample wastewater from planes

Infectious disease experts believe strategy more effective in slowing virus spread than new travel restrictions, as health data firm says thousands are likely dying daily in China

The United States is considering sampling wastewater taken from international aircraft to track any emerging new Covid-19 variants as infections surge in China, as UK-based health experts estimate about 9,000 people a days are now dying of the disease in China.

The proposed of testing wastewater by the US Centers for Disease Control and Prevention would provide a better solution to tracking the virus and slowing its entry into the US than new travel restrictions announced this week, three infectious disease experts said.
