The COVID-19 outbreak in China’s largest and busiest city of Shanghai remains “extremely serious” amid an ongoing lockdown confining around 26 million people to their homes, a city official said Tuesday. Director of Shanghai’s working group on epidemic control, Gu Honghui, was quoted by state media as saying that the outbreak in the city was “still running at a high level.” “The situation is extremely grim,” Gu said.

China has sent more than 10,000 health workers from around the country to aid the city, including 2,000 from the military, and is mass testing residents, some of whom have been locked down for weeks. Most of eastern Shanghai, which was supposed to reopen last Friday, remained locked down along with the western half of the city.

Officials would reevaluate preventative measures after the results of tests on all city residents are analyzed, Gu said. “Before that, citizens are asked to continue following the current lockdown measures and stay in their homes except for medical and other emergency situations,” Gu said. Shanghai has reported more than 73,000 positive COVID-19 infections since the resurgence(复苏) of the highly contagious omicron variant in March.

Shanghai recorded another 13,354 cases on Monday—the vast majority of them asymptomatic(无症状的) — bringing the city’s total to more than 73,000 since the latest wave of infections began last month. No deaths have been ascribed to the outbreak driven by the omicron BA.2 variant, which is much more infectious but also less lethal(致死的) than the previous delta strain. Gu said about 47,700 beds are available for COVID-19 patients, with another 30,000 beds to be ready soon. It wasn’t clear how many beds were available for patients placed under observation, who number more than 100,000 according to city health authorities.
