Why did the same person get a call to prevent and control the epidemic?

At present, most of the information mainly comes from the following three aspects:

First, the investigation letter issued by the superior disease control department or administrative department, including close contacts (referred to as close contacts), close contacts of close contacts (referred to as sub-close contacts), general contacts, key risk personnel, etc. ;

The second is the list of epidemic-related personnel in key areas pushed by big data;

The third is the process adjustment of the case or close contact.

The sending time of investigation information is uncertain, which may be in the daytime or in the early morning. After receiving the investigation letter, the CDC staff need to complete the process adjustment or information verification immediately. If the information in the investigation letter is incomplete and there is no contact information, the public security system needs to cooperate.

If you receive a call from the CDC, it may be that you have had close contact with a confirmed case or asymptomatic infected person recently, or have had close contact with the case. For the health and safety of you and your family, so that people who may be infected can be investigated and treated as soon as possible, please provide information patiently and truthfully.

The CDC staff will first verify whether the contents in the investigation letter are accurate, whether I am in the jurisdiction and the specific location. If you are in the jurisdiction, continue to ask your basic information (name, ID number, current address, work unit, etc. ).

Next, I will ask you about your action track and specific time in recent days, who you contacted, where you went, your peers, your roommate and all the people you may contact. If the transferred person is not in the jurisdiction, it is necessary to find out his current position and report it to the superior disease control department, which will transfer it to the local disease control department for investigation.
