What are the three epidemic districts The epidemic area refers to the city or the district

The three epidemic zones are the closure and control area, the control area, and the prevention area.

After the outbreak of the new crown epidemic, according to the level of the risk of epidemic transmission, the community prevention and control will be accurately divided into three areas, and classified management will be implemented.

Staff in the prevention zone, guards in the control area, public security police, grid personnel, patrol personnel, material distribution personnel and other volunteers should wear medical surgical masks, wear medical gloves if necessary, keep a distance of one meter, use hand sanitizer, and do hand hygiene at all times.

It is divided into a closure and control area, a control area, and a prevention area.

1. The closure and control area adheres to the principle of "regional closure, staying at home, and door-to-door service", and strictly implements home isolation.

Measures, all the exits of the closed and controlled communities are on duty by police, there are special personnel on duty at the entrance of the building, and there are electronic "door magnets" at the door of the residents, so that residents can truly stay at home and strictly prevent the risk of epidemic spillover;

2. The control area adheres to the principle of "people do not go out of the community, it is strictly forbidden to gather", each household can go out of the house once a day to buy or pick up items at the designated place in the community, all people out of the house implement temperature measurement, verification and registration, arrange staff to be on duty 24 hours a day at the exit of the community, and arrange police patrols around the area to implement relevant control policies;

3. The prevention zone adheres to the principle of "strengthening social control and strictly restricting the gathering of people", and residents do a good job of self-health monitoring, minimize going out, and conduct regular nucleic acid testing.

Classification Criteria:

Cases and asymptomatic infections.

The residential area where the residence is located and the surrounding area with frequent activities can be classified as a closed and controlled area. 2 days before the onset of the case or 2 days before the asymptomatic infected person tested positive to the isolation management, if there is a high possibility of transmission to people in the workplace, activity and other areas, and close contacts.

It is difficult to determine the close contact tracking of close contact, and the relevant area can also be divided into closed and controlled areas.

The above content reference: People's Daily Online-Jinnan District of Tianjin Municipality strengthened the management of the "three zones" to curb the spread of the epidemic.

The three epidemic zones are the closure and control area, the control area, and the prevention area.

After the outbreak of the new crown epidemic, according to the level of the risk of epidemic transmission, the community prevention and control will be accurately divided into Sanmina District, and classified management will be implemented.

Workers in the prevention area, guards in the control area, public security police, grid personnel, patrol personnel, material distribution personnel and other volunteers should wear medical surgical masks, wear medical gloves if necessary, keep a distance of one meter, use hand sanitizer, and do a good job of hand hygiene at all times.

The definition of the key areas of the epidemic is not uniform in different regions. For example, Yangzhou and Wuxi not only clearly define seven provinces as key areas for the epidemic, but also have a "wait" word, which means that other provinces and cities may also be classified as key areas for the epidemic. Another example is that some cities have identified more than 1,000 confirmed cases as high-incidence areas.

Obviously, the number of confirmed cases is the main indicator for identifying the priority areas of the epidemic. At present, Hubei Province has the largest number of confirmed cases and is recognized as a key area for the epidemic. However, there does not seem to be a unified standard for which other provinces should be classified as key epidemic areas, and if more than 1,000 cases are used as the criterion, only four provinces are currently key or high-risk areas.

However, Yangzhou and Wuxi have stricter identification standards.

a.Low-risk areas.

Implement the strategy of preventing foreign imports, fully restore the order of production and life, cancel road traffic restrictions, help enterprises solve problems and problems in terms of employment, raw materials, capital and equipment, etc., and set conditions for enterprises to resume work and restore production without delay, and shall not delay the time for enterprises to resume work and production under the pretext of approval, filing, etc.

b.Medium-risk areas.

Implement the strategy of preventing the import of external and internal proliferation, restore normal production and life order as soon as possible and in an orderly manner, organize personnel to return to work in an orderly manner, guide employing enterprises to strictly implement requirements such as disinfection, ventilation, and temperature measurement, reduce personnel density, reduce personnel gathering, strengthen personnel prevention and protection, and eliminate risks and hidden dangers, so that epidemic prevention and control and enterprise resumption of work and production are promoted simultaneously.

c.High-risk areas.

Implement the strategy of internal prevention of proliferation, external prevention of export, and strict control and control. We must continue to concentrate on epidemic prevention and control. After the epidemic is effectively controlled, the scope of resumption of work and production will be expanded in an orderly manner.

There is a premise that high-risk areas should also ensure the normal operation of epidemic prevention and control, the operation of public utilities, the necessities of people's lives, and other enterprises that involve important national economy and people's livelihood.

An endemic area is an area where a virus or pathogen can be transmitted, and the size of an endemic area is limited by the mode of transmission and environmental conditions. When the number of infectious diseases reaches a certain number, and they intersect, expand, or overlap with each other, an epidemic area is formed.

In China, the "epidemic area" refers to the World Health Organization.

WHO) or the World Organisation for Animal Health (OIE) or the International Plant Protection Convention (IPPC) and recognized by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, as infectious diseases.

Epidemiological characteristics or epidemiological characteristics of animal and plant diseases, countries or regions where infectious diseases or other outbreaks occur. The epidemic area is divided into animal infectious disease epidemic area, plant infectious disease epidemic area, and human infectious disease epidemic area.

Causes of formation

The formation of epidemic areas is caused by the generation of epidemics, and epidemics often occur in humans, animals, or plants, and are contagious, generally by parasites.

Caused by bacteria, viruses and other microorganisms.

It is a class of epidemic diseases that cause serious harm to humans and animals and require urgent and severe compulsory prevention, control, and extinguishing measures. It may cause major economic losses, and it is necessary to take strict control and extinguishing measures to prevent the spread of Class II epidemics. Common and frequent, hail and reed may cause major economic losses and losses, and there are three types of diseases that need to be controlled and purified.
