BEIJING/SHANGHAI (Reuters) – Some key industries in Wuhan, the Chinese city at the epicenter of the coronavirus epidemic, were told they can resume work on Wednesday, a day after President Xi Jinping visited the city for the first time since the outbreak began. The city of 11 million has been in lockdown since late January, but Xi’s visit signaled the tide was turning in the government’s favor as it fights to contain a virus that as of Tuesday had infected 80,778 people in China and killed 3,158. Drawing confidence from Xi’s visit and falling new infections, the Hubei provincial government posted a notice on its website saying public transport workers in Wuhan, and workers engaged in making medical supplies and producing daily necessities would be allowed to return to work.
