Gu said Shanghai was divided into 7,624 areas that are still sealed off, with a group of 2,460 now subject to "controls" after a week of no new infections, and 7,565 "prevention areas" to be opened up after two weeks without a positive case.
Those in "prevention areas" who move around their neighbourhoods must observe social distancing and could be sealed off again if there are new infections, Gu added.
One of the first districts to release its list was the industrial area of Jinshan on Shanghai's southwestern edge, which posted the names of residential sites still in high- and medium-risk categories.
