BEIJING, CHINA - JULY 01: A Chinese epidemic control worker wears a protective suit as she performs a nucleic acid swab test for COVID-19 on a man at a government testing site on July 1, 2020 in Beijing, China. While Chinese government medical officials have said they believe they have contianed the outbreak, authorities are trying to control the spread of COVID-19 infections linked to the Xinfadi wholesale food market, Beijing's biggest supplier of produce and meat. More than 8 million people have undergone nucleic acid tests for COVID-19 at dozens of sites across the city in recent days, with officials using contact tracing to target high and middle risk areas and people who may have had contact with the market or food that came from there. Several neighborhoods have been locked down and a number of other food markets have been closed. (Photo by Kevin Frayer/Getty Images)
