What scope does the epidemic area refer to?

An epidemic area refers to an area where viruses or germs can spread, and the scope of the epidemic area is limited by the mode of transmission and environmental conditions. When the number of infectious diseases reaches a certain number, when they cross, expand and overlap, an epidemic area is formed.

In China, "epidemic area" refers to the countries or regions where infectious diseases or other epidemics occur, which are published by the World Health Organization (WHO) or the World Organization for Animal Health (OIE) or the International Plant Protection Convention (IPPC) and approved by the AQSIQ. Epidemic areas are divided into animal epidemic areas, plant epidemic areas and human epidemic areas.

Epidemic areas are caused by epidemics, which often occur in people, animals or plants. They are collectively referred to as infectious diseases and are generally caused by parasites, bacteria, viruses and other microorganisms.

It is an epidemic disease that is seriously harmful to people and livestock and needs urgent and severe compulsory prevention, control and extermination measures. It may cause great economic losses, and strict control and eradication measures are needed to prevent the spread of the disease. There are three kinds of diseases that are common, may cause great economic losses, and need to be controlled and purified.

The latest epidemic prevention and control policy in Sanya (updated on 202 1 10 2 1)

I. Current medium risk areas in domestic risk areas (5)

I. Medium-risk areas (5)

Interpretation of the policy: The personnel in the above-mentioned risk areas will be quarantined at the port of entry in Qiong for 14 days, and will be monitored at home for 7 days after the quarantine expires.

2. Epidemic-related areas: the current epidemic-related areas (17).

Policy interpretation:

Persons who have tracked the above epidemic areas within 1 and 14 days must pass two nucleic acid tests within 48 hours (the interval between sampling is more than 24 hours, and the time from the second test result to the take-off is within 48 hours. Assuming that the time of nucleic acid results in a city is within 24 hours and the departure time of a passenger flight is 10: 00 on the morning of 29th, then samples can be taken at 10: 00 on the morning of 26th and 27th, and the second results can be taken within 48 hours. It is also necessary to carry out landing nucleic acid testing, report to the community after arriving in Qiong and conduct "three days and two inspections". Those who fail to carry nucleic acid twice within 48 hours cannot board the plane.

2. Special circumstances: there is a track in Beijing within 14 days, but there is no track in Fengtai District, so it can pass normally after signing the letter of commitment.

3. travel itinerary reminds people who have lived in the provinces and cities where the risk area is located (divided by the epidemic areas announced by the district) to cooperate with the port prevention and control unit for verification after arriving in Qiong. The port prevention and control unit will check the relevant information of personnel epidemic situation and determine the follow-up disposal measures according to the prevention and control requirements of Sanya City. (e.g. verification of travel trajectory, information registration, detection and observation of landing nucleic acid and other related prevention and control measures)
