Do contacts of sub close contacts need to be quarantined?

According to the relevant regulations of the epidemic, sub-close contacts need to be quarantined for 7 days for medical observation. If the nucleic acid test results of the new crown pneumonia in the previous 7 days are all negative, and the nucleic acid test results of the new crown pneumonia of the close contact with them are also negative, the sub-close contact can be released from isolation.

After some areas are lifted, they need to be quarantined at home for 7 days, and nucleic acid testing will be done on the first day of home isolation. During health monitoring, it is recommended to reduce unnecessary movement and take personal protection when going out. It is best not to attend meetings, exhibitions, travel, dinners and other gatherings.

Contacts of sub-close contacts need to be quarantined. Sub-close contacts will first be quarantined for 7 days for observation, and samples will be taken every day for nucleic acid testing during these 7 days, and if they are all negative, the close contacts they are in contact with will be tested for nucleic acid testing.

It is also negative, and the centralized isolation can generally be lifted, but the isolation time may be different depending on the risk of the epidemic in different places. If the close contact is positive for the new crown nucleic acid, such sub-close contacts need to be managed according to the close contact, the isolation period should be extended and the new crown nucleic acid test should be taken every day.

Precautions during quarantineAll direct contact with the outside world is prohibited during the quarantine period, and all people must be quarantined at home.

The subject issues a notice, advocating the use of WeChat, text messages, and other means to make notices, and the person being informed should confirm receipt of the notification information, and the urban community should make an announcement on the first floor of the building unit where the home isolation subject is located. All subjects in home isolation must have their body temperature checked once a day in the morning and once in the evening, and the medical staff in the work team must make a registration record.

Need.

The close contacts of the sub-close contacts are generally the close contacts of the close contacts of the confirmed persons during the epidemic prevention and control period, and they are the sub-close contacts, and they are the people who have had frequent contact with the sub-close contacts and are at key risk.

The difference between sub-close contact and general contact1. Close contacts.

Sub-close contacts refer to those who have close contact with close contacts such as living together, working in the same confined environment, having meals and entertainment, but have not taken effective protection, and the key groups are family members and colleagues who have frequent contact with close contacts.

2. General contacts.

General contacts refer to persons who have been in contact with suspected cases, confirmed cases, and asymptomatic infected persons in the same means of transportation such as planes and trains, and in the process of living, studying, working, and receiving medical treatment, as well as those who have been exposed to public places such as shopping malls, bus stops, and subways, but do not meet the criteria for determining close contacts.

People who have been in contact with sub-close contacts need to be isolated, but they do not need to be centrally isolated, and they can be isolated at home. During the period of home isolation, strictly implement "one person, one household or one household", and take measures such as door-to-door magnetism or sealing, so as to "stay at home".

Nucleic acid testing will be conducted once a day for contact with sub-close contacts, and door-to-door sampling will be arranged by the territory. If there are people living in the same household, home isolation and corresponding frequency nucleic acid testing will be implemented together. On the 7th day of home isolation, the nucleic acid test result is negative before the home isolation can be ended.

Those who do not have the conditions for home isolation will continue to be quarantined for 7 days. On the 14th day, the sampling and testing of "people, objects, and environment" were carried out, and the results were all negative, and the isolation could only be released after the personal luggage was disinfected.

Handling of sub-close contacts.

If the nucleic acid test results of the new coronavirus are negative in the previous 7 days, and the nucleic acid test of the new coronavirus of the close contacts they have contacted is also negative, they will be released from isolation, and they must reduce their movement during the daily health monitoring period, do a good job of personal protection when going out, do not participate in meetings, exhibitions, travel, dinners and other gathering activities, and in principle, do not leave the county (city, district) where they are located until the end of daily health monitoring.

Yes, it needs to be quarantined. The sub-close contact of the new crown epidemic in Beijing spoke out in the "Nine Parties", "I was about to rest on Sunday night, and suddenly received a strange **, which was an unfamiliar number at the time, and I almost hung up (fortunately I didn't hang up). When I heard that the other party said that it was a disease control officer, I was startled and thought something was wrong.

When the other party said that I was identified as a sub-close contact, I was even more confused.

Although I have been paying attention to the news of the epidemic and the people in the epidemic recently, I feel that the epidemic is still very far away from me, and I am just a bystander standing in the distance. When I became an element of the epidemic news, I really felt the impact and anxiety. ”

Knowledge of new crown epidemic prevention and control:

1. If you work in a poorly ventilated and closed area, it is recommended to wear a mask when you go to work. The canteen is also a crowded place, and it is recommended that each unit can eat at a staggered peak to reduce the density of personnel.

2. When disinfecting the air with disinfectant, it must be an unmanned environment. Because if a person inhales the disinfectant, or if the disinfectant is sprayed repeatedly on the person's body, there is a potential risk.

Glad for your question. The quarantine period for close contacts is two weeks, or 14 days. The time to define this is also based on the data from the previous period and the characteristics of respiratory infections over the years.

Generally, the incubation period of respiratory viruses is mostly 3 7 days, so the time of the incubation period set in the guidelines, that is, if you are in close contact with a patient infected with the new coronavirus, if you are infected, the occurrence of clinical symptoms is generally 3 7 days. However, because there will be asymptomatic infections in people infected with the new coronavirus, a negative test for 14 days of isolation means a negative nucleic acid test for the new coronavirus to release the isolation, and it is still very necessary to isolate for 14 days.

Sub-close contacts need to be quarantined. If the nucleic acid test results of the new coronavirus in the previous 7 days are negative, and the nucleic acid test of the close contacts they have contacted is also negative, the centralized isolation medical observation will be lifted. If a close contact has tested positive in the previous two nucleic acid tests, the patients in close contact with him will be managed as close contacts.

According to relevant regulations, sub-close contacts will first be subject to 7-day centralized isolation medical observation, and if the nucleic acid test results of the new coronavirus in the previous 7 days are negative, and the new coronavirus nucleic acid test of the close contacts they have contacted is also negative, the centralized isolation medical observation will be lifted. If a close contact has tested positive in the previous two nucleic acid tests, the patients in close contact with him will be managed as close contacts.

Criteria for delineating risk areas1. Region: Take the street or township as the basic unit.

3. Epidemic situation: how many new crown cases have been accumulated and whether there is a cluster of epidemics.

The classification criteria for high, medium and low risk areas of the epidemic are based on whether there are confirmed cases of the new crown in the street or community within 14 days and how many new crown cases there are, and the specific classification standards need to be appropriately adjusted according to the changes of the new crown pneumonia epidemic.

Sub-close contacts need to be isolated and excavated in a centralized manner.

Close contacts: 14 days of centralized isolation medical observation, and nucleic acid testing will be conducted on the first and 14th days of centralized isolation medical observation. After the isolation is lifted, home health monitoring will be carried out for 7 days, during which body temperature and symptoms will be monitored, and no going out unless necessary, personal protection will be done when going out, and a nucleic acid test will be carried out on the first day of home health monitoring.

The Omicron variant has the following characteristics:

First, it carries 32 different mutations on the spike protein of the new coronavirus, while the spike protein mutation of the Delta strain has 16;

Second, the incubation period is short, the contagion is very strong, and the transmission speed is fast and simple. Some foreign data show that the intergenerational transmission days can be as short as 2-3 days is a generation, and the transmissibility is 5 times stronger than that of the Delta variant;

The third is that the spread of hidden friends is very strong. Symptoms are subtle and are more likely to be sporadic or concentrated.

Legal analysis: Sub-close contacts are quarantined for 14 days and home for 7 days. Persons who have close contact with suspected and confirmed cases but have not taken effective protection 4 days before the onset of symptoms, or 4 days before the sampling of asymptomatic infected persons, will be judged as close contacts by epidemiological investigation professionals based on the results of epidemiological investigations and the big data information provided by relevant departments.

For example, family members living together in the same room, people in close contact in the office, workshop, team, elevator, canteen, classroom, etc., people who eat together, play together, and provide catering and entertainment services in a closed environment, etc.

Legal basis: Article 40 of the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases When disease prevention and control institutions discover an epidemic situation of an infectious disease or receive a report of an epidemic situation of an infectious disease, they shall take the following measures in a timely manner: (1) Conduct an epidemiological investigation of the epidemic situation of the infectious disease, put forward suggestions for the demarcation of epidemic points and epidemic areas according to the investigation situation, carry out sanitary treatment of the contaminated places, and conduct medical observation and take other necessary preventive measures in the designated places for close contacts. and propose an epidemic control plan to the health administrative department; (2) When infectious diseases break out or become epidemic, carry out sanitary treatment of epidemic points and epidemic areas, propose epidemic control plans to the health administrative departments, and take measures in accordance with the requirements of the health administrative departments; (3) Guide lower-level disease prevention and control institutions to implement measures for the prevention and control of infectious diseases.

Legal Analysis: Quarantine Required. Because infectious diseases spread widely and widely. There is a high probability that there are potentially infected people, so anyone who has been in contact needs to be quarantined.

Legal basis: Measures for the Implementation of the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases Article 52 In areas where infectious diseases have broken out or are endemic in areas, local authorities shall, according to the needs of the epidemic control of infectious diseases, organize departments such as health, medicine, public security, industry and commerce, transportation, water conservancy, urban construction, agriculture, commerce, civil affairs, post and telecommunications, radio and television to take the following preventive and control measures: (1) Rescue and isolate patients**; (2) Strengthen fecal management and remove garbage and dirt; (3) Strengthen the management of tap water and other drinking water, and protect drinking water sources; (4) Eliminate vector insects, snails, rodents and other infected animals; (5) Strengthen the health management of activities that are prone to the spread of infectious diseases; (6) Carry out the publicity of disease prevention knowledge; (7) Organizing quarantine, preventive medication, emergency vaccination, etc., for patients with infectious diseases, pathogen carriers, and people in close contact with infected animals; (8) Drugs, biological products, disinfectants, equipment, etc. necessary for the prevention and control of the epidemic; (9) Guarantee the daily necessities of residents.

Regulations on Emergency Response to Public Health Emergencies Article 38 If an infectious disease patient or a suspected infectious disease patient is found on the vehicle in accordance with the provisions of the health administrative department and needs to take emergency control measures, the person in charge shall notify the stop ahead in the fastest way and report to the operator of the vehicle. The front stops and operating units of the means of transport shall immediately report to the administrative departments of the transport operators and the local people's health administrative departments at or above the county level. After receiving the report, the competent administrative department of health shall immediately organize relevant personnel to take corresponding medical measures.

For close contacts of infectious disease patients on the means of transport, the administrative departments of people's health at or above the county level or the administrative departments of railways, transportation, and civil aviation at the stopping points of the means of transport shall, in accordance with their respective duties, and in accordance with the provisions of the laws and administrative regulations on the prevention and treatment of infectious diseases, take control measures.

Where emergency control measures for infectious diseases need to be taken for personnel, means of transport, goods, containers, luggage, postal parcels, etc., involving border ports and entry and exit, it shall be handled in accordance with the provisions of border health and quarantine laws and administrative regulations.
