Disease control personnel are the frontline troops to fight the epidemic. In addition to sampling, testing and disinfection personnel, there are epidemiological professionals responsible for on-site investigation and epidemic analysis. They went to the scene to carry out investigations, communicate face to face with patients, ask patients about their exposure, contact, activity track and medical treatment before and after the onset of the disease, and look for clues related to the source of infection and the route of transmission. This can describe a clear transmission chain and provide a basis for judging close contacts, taking isolation measures and delineating disinfection scope.
Responsible for the health of oneself and others, let close contacts be investigated as soon as possible, provide real and detailed information to those involved in process adjustment, and let patients get treatment as soon as possible.
The purpose of "flow regulation"
The main purpose of "epidemic investigation" is to investigate the source of infection of cases, identify and track the risk groups such as close contacts, and investigate and analyze the transmission characteristics and chain of the epidemic. Through investigation and analysis, the disease control department can find out the virus source, infection route and transmission process of the epidemic, fill the loopholes in prevention and control in time, implement precise prevention and control, provide scientific basis for epidemic prevention and control, and block and control the spread of the epidemic.
In a word, Liu Diao is a Vlog, which depicts the life of the protagonist's eating, living, walking, eating, sitting and living ... and then find out whether there is the possibility of spreading diseases or the risk of being infected by diseases from the roads you have traveled, the people you met and what happened.
Who will get the call?
1, suspected case; 2. Confirmed cases; 3. Asymptomatic infected persons; 4. Risk personnel who have close contact with the above-mentioned personnel and may pollute the environment or * * * share the exposure.
What questions will Liu Diao ask?
With "people, cars, planes, networks and cards" as the key elements, the traffic controller will ask you the following information to track the spread path of the virus.
1. Personal information: name, age, place of residence, number of family members, vaccination history in COVID-19, etc.
2. Health status: whether you have been unwell recently, whether you have abnormal clinical symptoms such as fever, dry cough, fatigue, decreased sense of smell and taste, stuffy nose, runny nose, sore throat, conjunctivitis, myalgia, diarrhea, whether you have bought medicine or seen a doctor recently, whether you have done nucleic acid detection or lung CT screening, etc.
3. Life history of epidemic areas: whether you have been to high-risk areas or overseas recently, where you passed, and what you have done in these places;
4. Case contact history: mainly investigate people who have close contact with you, including passengers in the same car, close communicators, family members, colleagues and classmates, onlookers, etc. , and whether to wear a mask when touching;
5. Transportation: whether to take public transportation such as plane, train, car and ship; 6. Other necessary information: other information related to the epidemic situation or useful for epidemic prevention and control.
What if I get a call from the CDC?
People shouldn't be nervous when they receive calls from mobile phones. Being transferred does not mean being infected. It is possible that you have been exposed to positive cases recently, or the itinerary coincides with the trajectory of officially confirmed cases and close contacts in time and space. Please actively cooperate with professional investigators, carefully review recent health status and residence history, answer truthfully, and do not hide or lie.
Be sure to follow the advice of CDC staff, strengthen personal protection, and wait for the next steps such as isolation control or nucleic acid detection. Those who refuse to cooperate and deliberately conceal the situation and cause the spread of the epidemic will be investigated for responsibility according to law. Citizens' personal information and privacy are protected by law, and all information obtained by the disease control department is strictly confidential.
In a word, the formal transfer will not require or require the transfer object to provide information related to personal property and things for any reason. On the basis of learning to distinguish between regular telephone calls and fraudulent telephone calls by criminals, it is very important to actively cooperate with the telephone calls of disease control and public security departments, which is very important for epidemic disposal and prevention and control.
