Coronavirus: another Chinese city starts mass Covid-19 tests

A city in northeast China has started testing all of its residents for the coronavirus, becoming the second in the country to embark on such a mass screening programme.
Mudanjiang in Heilongjiang province near the border with Russia is conducting nucleic acid tests for all residents and plans to complete them all within a week, according to the municipal health commission.
Mudanjiang was under tremendous pressure from imported cases in April as an influx of Chinese nationals arrived from Russia overland through the border town of Suifenhe. While all of these patients have recovered, dozens of asymptomatic cases linked to those cases have been detected since.
