上海对哈尔滨来沪人员韩某某进行流调 - 2020年04月22日

The neighbor of an asymptomatic coronavirus carrier in northeast China, a woman surnamed Han, stayed in Shanghai for three days earlier this month and had been to a hotel and a beauty salon during that time, the local health commission said on Tuesday.
It said the health authority in Heilongjiang Province had tested Han five times between April 3 and 15, all with negative results.
After news reports that Han, who is related to a clustering infection case in Heilongjiang’s Harbin City, had visited Shanghai, the city's health commission immediately contacted Heilongjiang's health authority and was told that Han, a student of New York University student, had flown from New York on March 18 and made transfers in Hong Kong and Beijing to Harbin.
