How will secret connections be notified?

Close contacts and close contacts of patients diagnosed in COVID-19 need to be transported to a centralized isolation place for medical observation within 12 hours. Generally, such people are notified by telephone, text message, etc. If the second close contact receives a call from the traffic controller, don't panic, carefully review the recent trip and truthfully answer the traffic controller's questions so that the traffic controller can trace the source of infection as soon as possible.

If the positive infected person is a strict static manager, that is, non-mobile personnel under strict management, including family members, if they live in all independent kitchen and bathroom conditions, they are closely related to the people they live with, while the residents on the same floor and the upper and lower floors are closely related. If the residence does not have independent kitchen and bathroom conditions, it should be judged as close contact with the people who live and work together, and the people who live on the same floor or village house with them in daily contact, while other residents in the building/village house are judged as sub-close contact.
