The circuit breaker mechanism for inbound flights will be abolished, risk zones will be divided into "high and low" categories, unscientific practices such as "two tests a day" and "three tests a day" for nucleic acid testing will be corrected, and stocks of drugs related to COVID-19 treatment will be accelerated. After the announcement of the 20 optimization measures, the society has aroused wide concern.
Local governments have implemented 20 optimization measures. How is the risk zone delineated? How to determine the dense joint, space-time adjoint, etc.? Is it necessary to insist on nucleic acid? Focusing on hot issues of public concern in the process of implementation, relevant experts under the joint prevention and Control mechanism of The State Council made authoritative responses.
Q1. Do the 20 optimization measures mean easing up on prevention and control? Will it increase the risk of the outbreak spreading?
A: The optimization and adjustment of prevention and control measures does not mean to relax the prevention and control, still less to relax or "lie down". It means to adapt to the new situation of epidemic prevention and control and the new characteristics of the novel coronavirus mutation, adhere to the established prevention and control strategies and guidelines, and further make the prevention and control more scientific and precise.
These adjustments are based on the experience of epidemic prevention and control practices in multiple places and relevant assessment data. Over the past three years, China has optimized and adjusted prevention and control measures in light of the global epidemic situation and the mutation of the virus, as well as China's practical experience in epidemic prevention and control. Every adjustment and optimization has been evaluated repeatedly and scientifically to ensure that the risks are under control.
Twenty optimization measures are more scientific and accurate measures that seek progress while ensuring stability, take small steps without stopping, and are in line with China's national conditions. These adjustments call for more standardized and faster prevention and control, the control of key risks, the implementation of the implementation, the elimination of the elimination of the firm, the full use of resources, improve prevention and control efficiency.
Q2: When people respond, "community outbreak area" and "community transmission area" are proposed in their local areas. After twenty optimization measures are proposed, how to define the risk area?
A: Twenty optimization measures have adjusted risk areas from three categories of "high, medium and low" to two categories of "high and low". Under the premise of scientific and accurate control of risk areas, the control scope and personnel should be reduced to the minimum.
According to the practice application of the ninth version of the prevention and control protocol and the evaluation in July and August this year, the positive detection rate of the medium-risk area is about 3/100,000, which is very low risk. In order to reduce control areas and personnel as much as possible, the designation of medium-risk areas was cancelled.
According to the 20 optimization measures, in principle, the areas where the infected people live, work and activity places with frequent activities and high risk of epidemic transmission are designated as high-risk areas. High-risk areas are generally designated by units or buildings, and cannot be expanded at will. Other areas of the county (city, district, banner) where the high risk area is located shall be designated as the low risk area. No new infections were found in the high-risk area for five consecutive days, and the risk was reduced to a low-risk area. High risk areas that meet the conditions for unsealing should be unsealed in time.
Question 3: There is a response from the masses. At present, there are a variety of decisions such as dense connection and space-time conjoint. What kind of epidemic prevention measures should be taken according to different decisions?
A: Close contact is short for close contact, which generally refers to people who have had close contact with suspected or confirmed cases from 2 days before the onset of symptoms, or asymptomatic infected persons from 2 days before the sampling of samples, but did not take effective protection. The ninth edition of the prevention and control plan lists nine types of close contacts, including those who live together.
In Article 20 of the optimization measures, it is clear that for close contacts, the management measures of "7-day centralized quarantine + 3-day home health monitoring" will be adjusted to "5-day centralized quarantine + 3-day home quarantine", during which time they will be assigned management code and not allowed to go out. At the same time, it is required to determine the close contacts promptly and accurately, and no longer judge the close contact.
The time and space accompanying personnel are the exposed personnel in the epidemic site. According to the ninth version of the prevention and control plan, such personnel are required to conduct "two inspections in three days" after the transfer, and timely investigation.
Regardless of the control method, the control time is calculated from the time of the last exposure of personnel. For controlled times, the starting time should be based on the time judged to be the last exposure and should not be based on the time traced to this contact.
Question 4: At present, some cities require access to public places to issue a negative nucleic acid certificate while reducing nucleic acid testing sites. Many people are concerned about: Do we need to insist on nucleic acid testing?
A: According to the ninth version of the prevention and control plan, after the outbreak of the epidemic, based on the flow investigation and judgment, it is clear that the transmission chain is clear, and there is no community transmission, there is no need to carry out nucleic acid testing for all personnel in the region, but only need to carry out nucleic acid testing for the risk areas and key personnel at risk of infection, and carry out rapid epidemic treatment.
Article 20 Optimization measures further stress that areas without epidemic outbreaks should carry out nucleic acid testing for high-risk positions and key personnel in strict accordance with the scope determined in the ninth version of the prevention and control plan, and not expand the scope of nucleic acid testing. Generally, nucleic acid testing of all personnel is not carried out according to administrative region, but only when the source of infection and transmission chain are unclear, and the community transmission time is long and the epidemic situation is unclear.
The Article 20 optimization measures also require the formulation of specific implementation measures for standardizing nucleic acid testing, reiterating and refining relevant requirements, and correcting unscientific practices such as "two tests a day" and "three tests a day".
