On November 4, at the press conference on the prevention and control of new crown pneumonia in Gansu Province (the seventeenth session), Zhang Hong, chief physician and chief physician of the acute infectious disease prevention section of the Gansu Provincial Center for Disease Control and Prevention, pointed out what is "fluctuation", How should ordinary people respond with cooperation?

He said that the so-called "fluid regulation" is the abbreviation of epidemiological investigation, and it is one of the very important methods of controlling infectious diseases including new coronary pneumonia.

  In layman's terms, it is to show how the cases are transmitted through investigation, to find the source of the infection, the possible infections and the polluted environment.

In a word, the flow regulation is to extinguish the "fire" that may occur in the epidemic at an early stage, cut off the route of transmission, and prevent further spread.

  When carrying out the flow adjustment work, due to the long time span, the personnel cooperating with the investigation may not remember some things clearly.

Therefore, when inquiring about cases, we will use special time nodes (such as holidays), iconic characters and events to remind and help the patients themselves, or the treating doctors, family members, and insiders through observation, inquiries, and access to information. Case recall, including channels and information such as mobile payment records and communication records.

For key links that are difficult to identify, joint prevention and control mechanisms are used when necessary, with the support of public security, industry and information departments, and big data information to find out.

It is the legal obligation of every citizen to cooperate with epidemiological investigations and provide information truthfully.
