How long will it take for the third-level secret contact to receive the notice?

Sub-close contacts refer to close contacts of close contacts of patients diagnosed in COVID-19, so they are called sub-close contacts. Generally, sub-close contacts need to be isolated for medical observation for about seven days. Generally, this happens, and the flow controller will call to inform you, usually within 12 hours.

The sub-secret receiver doesn't need to panic when he receives the call from the dispatcher. As long as he answers the dispatcher's questions truthfully and carefully reviews his recent trip, the dispatcher can trace the source as soon as possible, which is conducive to the development of epidemic prevention work.

According to the "novel coronavirus Prevention and Control Plan" issued by the National Bureau for Disease Control and Prevention on May, 20265438 (the eighth edition), when COVID-19 infection occurs, according to the principle of territorial management, the joint prevention and control mechanism at the county (district) level where the medical and health institutions reporting the cases and asymptomatic infections are located will organize the epidemiological investigation of the cases and asymptomatic infections within 24 hours as far as possible. According to the investigation results, the infected person was identified as A, and was divided into three groups according to the risk from high to low: close contact B, close contact C and general contact D of infected person A.

Close contacts refer to those who have had close contact with suspected cases and confirmed cases 2 days before symptoms appear (which can be extended to 4 days according to actual conditions in some areas), or those who have not taken effective protection since 2 days before asymptomatic infected persons are sampled.

Generally, it includes the following situations:

1. Family members sharing a room;

2. Direct nursing or providing medical care services;

3. Medical personnel who may carry out aerosol diagnosis and treatment activities in the same space;

4. In offices, workshops, teams, elevators, canteens, classrooms and other places where people are in close contact;

5. Persons who share meals, entertain together and provide catering and entertainment services in a closed environment;

6. Medical personnel, family members or other personnel who have close contact with the case;

8. Persons exposed to the environment and articles contaminated by cases or asymptomatic infected persons;

9. On-site investigators evaluate other personnel who meet the criteria for judging close contacts.

According to the results of epidemiological investigation, close contact B was transported to a centralized isolation place for medical observation within 12 hours. On the 4th, 4th, 7th, 1 4th day of centralized isolation medical observation, the close contacts were tested for nucleic acid. Nucleic acid detection was carried out on the second and seventh days after isolation.
