Health official: All confirmed cases in Shanghai linked

Chen Xiaojie, vice-governor of north Shanghai's Baoshan district, said that authorities have been assisting residents from the district's No 1 and No 2 section of Linjiang Xincun residential neighborhood, which was categorized as a medium-risk area on Saturday after a couple was found to be infected.

"Food, drugs, articles for daily life, and trash collecting service are provided in a timely manner to the residents under home quarantine. For some senior and disabled residents who live on their own, neighborhood workers also provide additional help such as delivering three meals to them every day," she said.
