WHO Expert Calls For Patience Over Sensitive Wuhan Probe By Laurie CHEN 02/03/21 AT 1:33 AM There will be no quick answers into the origins of the coronavirus, one of the World Health Organization experts on a mission to the Covid-19 ground zero in central China told AFP. Hung Nguyen-Viet, who is visiting various virus-linked sites in the city of Wuhan with the team, said starting the investigation more than one year after the pandemic began was not ideal, but added that the mission was progressing well. The politically sensitive trip -- which Beijing had delayed throughout the first year of the pandemic -- aims to explore how the virus first jumped from animals to humans before killing millions worldwide since it first emerged in Wuhan in late 2019.
