Extended data:

The purpose of traffic adjustment is to understand: in the past period of time, the action trajectory of key people, the people they met and what happened. To find out the exposure, contact, activity track and medical treatment of the case or the person who is in close contact with the case. Search for clues related to the source and route of infection and clarify the transmission chain, so as to provide basis for judging close contacts, taking isolation measures and delineating disinfection scope. Therefore, the adjustment of the epidemic situation is also to protect others from infection and control the spread of the epidemic.

After identifying themselves, the staff will ask for detailed personal information, but will not ask for property and other issues unrelated to the spread of the disease. All the work of epidemic control does not involve the promotion of "anti-epidemic drugs" or money. As long as the call received involves product promotion and charging fees, it can be judged as fraud. They should hang up directly and provide clues to the public security organs.

All information obtained through traffic transfer is strictly confidential. Protecting personal privacy is the requirement of medical ethics and professional ethics, and it is also a clear provision of the law, and it is also the premise of all medical activities. Like clinicians, only by obtaining accurate disease information can we give a correct diagnosis and treatment plan; Only by obtaining real and effective crowd information can we scientifically evaluate the epidemic situation and take correct prevention and control measures! Therefore, please take the initiative, cooperate and trust when you encounter calls or chats on the phone or WeChat!
