WUHAN, China (AP) — A World Health Organization team has emerged from quarantine in the Chinese city of Wuhan to start field work in a fact-finding mission on the origins of the virus that caused the COVID-19 pandemic. They were required to complete a 14-day quarantine after arriving in China. The mission has become politically charged, as China seeks to avoid blame for alleged missteps in its early response to the outbreak. A major question is where the Chinese side will allow the researchers to go and whom they will be able to talk to.
