China's Jiangsu reports 31 new COVID-19 locally transmitted confirmed cases
East China's Jiangsu Province on Monday reported 31 locally transmitted confirmed cases of COVID-19, all registered in the provincial capital Nanjing, local authorities said on Tuesday.
Seven of the cases were previously categorized as asymptomatic, the provincial health commission said.
Jiangsu also reported three imported confirmed cases on Monday.
By the end of Monday, there were 119 confirmed cases (107 locally transmitted) being treated in hospitals in Jiangsu, while 24 asymptomatic cases (six locally transmitted) were under medical observation, the commission said.
The province has seen daily increases of locally transmitted COVID-19 cases, mostly in Nanjing, since a few airport workers tested positive for the coronavirus last week.
The city's center for disease control and prevention said the COVID-19 cases in Nanjing have been identified as being infected by the highly contagious Delta variant.
Nanjing, a megacity with a population of more than 9.3 million, has launched its second all-inclusive nucleic acid testing campaign and urged residents not to leave the city unless necessary.
On Tuesday, another 11 villages and residential complexes in Nanjing were added to the list of medium-risk areas for COVID-19. The city now has four high-risk areas and 36 medium-risk areas.
