Shanghai on Covid-19 alert as new cluster closes bubble tea shop
- Infections believed to have spread from an imported case, giving Shanghai its first symptomatic cases in a month
- City tightens its rules for people undergoing health monitoring at home after their quarantine

The city’s health department reported two new local symptomatic cases and three asymptomatic cases. It had not reported a symptomatic case since December 17, and its previous asymptomatic case was on Friday last week.
It was found that all five new cases shared the same transmission chain as an imported asymptomatic case reported on Tuesday – that of a Chinese student studying in the United States who had arrived in China on December 21.
The two symptomatic cases were close contacts of the student and worked at the bubble tea shop. The asymptomatic cases were another employee of the shop, a relative of one of the employees, and another close contact of the student. All but one were fully vaccinated, the Shanghai health department said.
The bubble tea shop, in Jingan district in downtown Shanghai, has been closed.
