Nearly a third of the patients in the city of Tianjin were tied to a single mall. Officials estimated that nearly 12,000 people had been there in late January.
Nearly a third of the confirmed coronavirus cases in Tianjin, a city of more than 15 million about 70 miles southeast of Beijing, have been linked to one department store, adding to fears about rapid transmission in tightly clustered communities.
Of 102 confirmed cases in the city, at least 33 patients worked or shopped at a department store in the Baodi district, or had close contact with employees or customers, according to the Tianjin health authorities. Many of them had no history of travel to Wuhan, the city where the outbreak emerged.
Officials estimated that 11,700 customers had visited the shopping complex during a period in late January. The authorities said that those customers would be quarantined, and that the store itself, which they did not identify, had been sealed and disinfected.
It was not immediately clear how the authorities had tracked the shoppers, but health officials in the city have put out alerts on social media and on state news outlets urging residents to contact the government if they visited the store recently. News reports also said residents had been asked at various checkpoints in the city if they had been there.
In addition, emergency measures were imposed over sections of Baodi — home to nearly one million people — with all but two entrances and exits for certain residential areas sealed off and security personnel on round-the-clock patrols. Some residents were allowed to leave their homes only once every two days.
