Authorities of the eastern Chinese metropolis of Shanghai announced on Tuesday that, after more than a month and a half – in some areas, more than two months – of strict lockdowns, it has managed to cut the chain of community Covid-19 transmission in all of its 16 districts.

The deputy director of the Shanghai Municipal Health Commission, Zhao Dandan, assured at a press conference that all the city's districts have entered the phase called "zero social transmission," reported state news agency Xinhua.

This term refers to a situation in which, for three consecutive days, less than one case is detected among every 100,000 residents of "precautionary" and "controlled" areas, as well as in those that have already been unconfined.
