The major eastern Chinese city of Nanjing recorded another 31 locally transmitted COVID-19 cases on Tuesday, as authorities announced more than 1.5 billion doses of vaccine have been administered around the country.
The new cases bring Nanjing’s total to more than 106 over recent days. The virus circulating in the city has been identified as the delta variant, according to local officials.
The city has been carrying out mass testing and placed tens of thousands of people under lockdown. Along with near-universal indoor mask wearing, China has utilized such practices to largely contain the domestic spread of the virus.
