Protective suit-clad inspectors in the epicentre of China's viral outbreak went door-to-door on Wednesday to find every infected person in the central city suffering most from an epidemic that is showing signs of waning as new cases fell for a second day.
Wuhan, where the new form of coronavirus emerged, is on the final day of a campaign to root out anyone with symptoms whom authorities may have missed so far.
"This must be taken seriously," said Wang Zhonglin, the city's newly minted Communist Party secretary. If a single new case is found (after Wednesday), the district leaders will be held responsible."
