HARBIN -- Northeast China's Heilongjiang province now has no medium- or high-risk areas for COVID-19, after Wangkui County, where cluster infections were reported in early January, downgraded its risk level for the virus on Feb 22.

The anti-epidemic headquarters of Suihua city, which administers Wangkui, made the decision on Monday that Wangkui was downgraded to low-risk area as no new confirmed or asymptomatic cases were reported over the past two weeks.
