China reported on Tuesday just one new domestic coronavirus infection but found 20 more cases imported from abroad, threatening to spoil its progress against the disease.
The single case in Wuhan will boost China's view that it has "basically curbed" the spread of a disease that is believed to have emerged in a live animal market in the central city in December.
Wuhan and its 11 million people were placed under strict quarantine on January 23, with the rest of Hubei province going under lockdown in the following days.
Authorities tightened restrictions in the city even further on February 11, confining people to their homes as health workers faced a daily deluge of well over 1,000 cases a move officials say was critical in containing the virus.
Meanwhile, China on Tuesday began withdrawal of thousands of doctors and medical staff from Wuhan after the epicentre of the coronavirus outbreak reported just one confirmed case.
