As of the end of Thursday, 1,001 Covid-19 patients were receiving treatment in hospital and 618 asymptomatic cases, which are not included in the tally, were under medical observation.
The Chinese government first resorted to lockdown measures to stop the spread of the coronavirus about a year ago in Wuhan. Most people knew little about the virus at that time and hundreds of people died every week as hospitals became overwhelmed and doctors and scientists struggled to find a cure.
