East China's Shanghai has upheld differentiated prevention and control measures in its fight against the current COVID-19 resurgence to realize the "dynamic zero-case" target as soon as possible.

The municipal government has divided the city into three types of areas — 7,624 "lockdown areas" that are still sealed off, 2,460 "controlled areas" that have had no new infections for a week, and 7,565 "prevention areas" that have been opened up after two weeks of no positive cases.
