Original title: Yangzhou Disease Control: No new additions to the society in 14 days, medium and high-risk areas can be reduced to low-risk areas
In recent days, Yangzhou has lowered the risk levels in many areas. So, what are the basis and standards for risk level adjustment?
In this regard, at a regular press conference on epidemic prevention and control in Yangzhou on August 26, Zhang Jun, deputy director of the Yangzhou Center for Disease Control and Prevention, stated that according to the current general standards, there are no new cases in society within 14 days in low-risk areas. . Regardless of the original high-risk or medium-risk, as long as there are no new cases in society in the past 14 days, it can be lowered to low risk.
Zhang Jun mentioned that the determination of the regional risk level should be considered based on three dimensions: one is the region, which is generally based on streets and towns; the second is time. The current consensus is to refer to the 14 days determined by the incubation period; and the third is the epidemic situation. , How many cases are there, and whether there are clusters of epidemics. The specific classification criteria will be dynamically adjusted according to the situation and changes of the epidemic.
Specific to the outbreak in Yangzhou, in terms of time and epidemic situation, according to the current general standards in the local area, there are no new cases in the society within 14 days are low-risk areas, and there are no more than 10 cases or 1 cluster of epidemics. Medium-risk areas, more than 10 cases or 2 or more clusters of epidemics are high-risk areas.
According to Zhang Jun’s explanation, a clustered epidemic refers to the occurrence of more than 5 cases in a small area within 14 days.
The above standards apply both upward and downward adjustments. For example, if there are new cases in low-risk areas within 14 days, they can be raised to medium-risk; on the contrary, regardless of the original high-risk or medium-risk, as long as there are no new cases in the society in the past 14 days, it is fine. Downgrade to low risk.
Talking about the regional dimension, Zhang Jun said that in the early stage of the epidemic, the number of cases was small, and the travel trajectory was simple, the expert group studied and reported to the superior for the purpose of precise prevention and control and controlling the impact of the epidemic on society as much as possible. The risk area is delineated based on the community as a unit.
However, the number of new cases in Yangzhou remained in the double digits every day for several consecutive days. Multi-point continuous community transmission and family cluster transmission made the trajectory of cases complicated and the risk of transmission in the coverage area greatly increased. In order to control the flow of people as soon as possible In order to limit the spread of the virus, Yangzhou merged similar risk areas, and in principle divided them into streets (townships).
“In recent days, the number of new cases in Yangzhou has reached zero, but it does not mean that there is no risk.” Zhang Jun reminded that if you are in a medium-risk area, please continue to abide by the relevant prevention and control regulations. If you insist, you can return to normal as soon as possible. Being in a low-risk area does not mean that there is no risk. It is still necessary to take personal protection, wear masks, wash hands frequently, gather less, and develop healthy lifestyle habits.
