Medical workers from outside Wuhan pose for pictures with a Chinese Communist Party flag at the Wuhan Railway Station before leaving the epicenter of the novel coronavirus disease (COVID-19) outbreak, in Hubei province, China, March 17, 2020.

The Chinese city at the center of the coronavirus pandemic has for the first time reported no new daily cases, saying Thursday that there were no new cases Wednesday.

Wuhan has spent about two months on lockdown as authorities tried to stop the spread of the virus, and in recent weeks the number of new infections there dwindled.

Elsewhere in China, though, with health officials reporting 34 total cases Thursday among people who came from elsewhere, there is continued concern about such imported cases threatening the substantial progress the country has made.

China has been the hardest hit by the novel coronavirus since it emerged in late December, with about 81,000 total cases and 3,200 deaths. Most people who became sick have recovered.
