What is a close contact?
How to determine close contacts?
According to the "Prevention and Control Plan for the New Coronavirus Pneumonia" (Ninth Edition) close contact refers to: people who have close contact with suspected cases and confirmed cases starting 2 days before the onset of symptoms, or 2 days before the sampling of asymptomatic infected persons, but have not taken effective protection. If a later indicated case is found, the time limit for the determination of close contacts can be moderately extended; for cases discovered through high-frequency nucleic acid testing, the time limit for the judgment of close contacts is from the time of the last negative nucleic acid test to before isolation and control. The specific judgment principle shall be determined by public health professionals and technical personnel in accordance with the requirements of the "Guidelines for the Determination and Management of Close Contacts". Priority is given to determining and managing close contacts with high risk of infection such as frequent contact with cases and long duration. The scope of judgment of close contacts can be moderately expanded for cases with relatively dense and complex personnel.
What control measures should close contacts take
- Close contacts should be transferred to centralized isolation places within 8 hours after being discovered. 2 Take "7+3" management measures, conduct nucleic acid testing once every 123, 5 and 7 days of centralized isolation, and conduct nucleic acid testing once every 3rd day of home health monitoring. When the exposure time is clear, the isolation management period starts from the last exposure of the case or asymptomatic infected person; when there is continuous community transmission and the exposure time cannot be specified, the isolation management period starts from entering the isolation point. When a large-scale epidemic occurs in
- , in order to alleviate the resources of centralized isolation points, "5+5" measures can be taken, and nucleic acid testing will be carried out once every 1st, 2nd, 3rd, and 5th days of centralized isolation, and nucleic acid testing will be carried out once every 2nd and 5th days of home isolation medical observation.
- 14 children aged 414 and below, semi-self-care, no ability to take care of themselves, have serious underlying diseases and are in a stable period, pregnant women, mentally ill patients, and other special groups can take 7 days of home isolation medical observation.
When can close contacts lift the control? When the centralized isolation period expires, the items and environmental samples of
- are collected for nucleic acid testing, and they are all negative. Only after cross-infection of centralized isolation points is ruled out can centralized isolation be lifted. After the centralized isolation is lifted, the "point-to-point" closed loop will be returned to the residence. If the nucleic acid test for the item or environment is positive, the possibility of infection of the isolated subject needs to be further ruled out.
- The test results during home isolation medical observation can be lifted after all the test results are negative. After the suspected case is ruled out, close contacts can be released from isolation and medical observation.
What is "close connection"?
How to determine the close contacts of close contacts?
According to the "Prevention and Control Plan for the New Coronavirus Pneumonia" (Ninth Edition), close contacts of close contacts refer to close contacts that are judged as close contacts for a long time such as those with close contacts with high risk of infection. The principle of judgment is that for the first time the close contact and the case or asymptomatic infected person is exposed to the close contact before the close contact is isolated and managed, what control measures should be taken for close contacts of people who have close contacts but have not taken effective protection? Close contacts of close contacts of close contacts should be taken for 7 days of home isolation and medical observation, and nucleic acid tests should be carried out once each day, 4 and 7 days. The management period starts from the last contact with close contacts. If the corresponding close contact has positive results in the first two nucleic acid tests, it will be adjusted to be managed as close contacts.When can the close contacts of
close contacts be lifted?
If the close contacts are all negative during the isolation medical observation period, and the corresponding close contacts are both negative for the first two nucleic acid tests during the isolation period, they can be released from isolation on the 7th day; if the close contacts are released from the collection of isolation, the close contacts of the close contacts will also be released from isolation.
What are people exposed in the epidemic-related places?
How to expose people in the epidemic-related places?
If it is exposed to a densely populated and closed place such as suspected cases, confirmed cases and asymptomatic infections, in weddings (mourning) banquets, restaurants, supermarkets, shopping malls, agricultural trade (collective trade) markets, but does not meet the principle of determining close contacts and close contacts, it should be managed as an exposed person in the epidemic-related place.
What control measures should be taken for people exposed in epidemic-related places?
If the person who is evaluated as an exposed person in the site involved in the epidemic is high after infection, a nucleic acid test will be carried out on the first and third days after the judgment.
What should I do if other units in the same cell have
close contacts are controlled?
Try to minimize contact with others and pay attention to the health code status
- Before the seal (control) control is lifted, avoid going to the seal (control) control area or staying, wear masks throughout the process, and take personal protection and disinfection of the home environment.
- After contacting the unit elevator buttons, door handles and other public facilities, clean your hands in time. Do not touch your mouth and nose with your hands before doing hand cleaning.
- No dinner or parties, and no crowded public places.
- maintain a safe social distance, abide by respiratory etiquette, and use tissue or elbow to cover your mouth and nose when coughing or sneezing.
- Maintain good ventilation in the workplace and home, and try to ensure that the work/study place and residence are at the same time. If conditions permit, you can apply for online office or class to minimize contact with other people.
- If the health code becomes a yellow or red code, please report to the community immediately and follow the community's arrangements and handling.
cooperates with nucleic acid testing
cooperates with the community to do nucleic acid testing and take personal protection during the round-trip testing.
maintain a calm mind, actively report
maintain a calm mind, abide by the relevant community epidemic prevention regulations, attach importance to but not panic, and actively pay attention to the epidemic situation of the blocked (control) control unit. If you have close contact with key epidemic-related personnel in the blocked (control) control area, you should report to the community in a timely and proactive manner.
Do a good job in self-health monitoring
Maintain a regular daily routine, measure body temperature every morning and evening. Once you have symptoms of fever, sore throat, dry cough, fatigue, diarrhea, and loss of smell (taste), please wear a mask immediately, avoid taking public transportation, and go to the nearest fever clinic for medical treatment as soon as possible.
