Close contacts are isolated at home for a few days and taken to a centralized isolation point. Is the corridor about to be unsealed?

The unsealing of corridors, including residential areas, should be notified according to the specific announcement of this area, not based on personal random speculation. You can only leave the isolation place after specific notice, otherwise it will only cause more unnecessary indirect infections.

In addition to close contacts, sub-close contacts also need to be isolated, so how long do sub-close contacts need to be isolated, 7 days or 14 days, as the case may be.
