Authorities have yet to announce Covid deaths, but hospital workers have described a dire situation.
Authorities in Shanghai are struggling to deal with a suspected wave of Covid infections at a large hospital for the elderly, in a sign of how serious the outbreak is in China's biggest city.
A nurse told the BBC that the first positive cases were discovered at the facility - one of the biggest of its kind in Shanghai - three weeks ago. But workers say that it is hard to tell if the victims had died from Covid as there have been many infections. She told the BBC: "At first, we just kept working as usual, but later they started to block each department and the manager told us the real situation was much worse."A care worker who has been working at the hospital this week told the BBC that "sanitary conditions were pretty bad" when she arrived.
He says he has not been able to speak to his grandmother on the phone since shortly after the lockdown began on Monday. Staff who picked up when he called were unable to give any details about what she was being given to eat, or any medication administered, he said.
