Different nucleic acid detection strategies in different scenes are different?The Chinese disease control response is performed: clear source, clear communication chain, no community transmission, no need to conduct all -staff testing on the area where the epidemic is needed

On July 21, the State Council joint prevention and control mechanism held a press conference on the relevant situation of the prevention and control of the epidemic.

Mi Feng, a spokesman for the National Health and Health Commission and deputy director of the Propaganda Department, said at the press conference that at present, the global epidemic is still at a high level, and the number of new diagnosis cases has exceeded 1 million times. It has become the major popular plants in the world, and the pressure on foreign defense input is increasing.

"Recently, the local clustering epidemic has been reported in many places across the country. There are multiple transmission chains, and the situation of the epidemic prevention and control is severe and complicated. The epidemic. "Mi Feng emphasized.

The "New Coronatte Pneumonic Pneumonia Prevention Plan (Ninth Edition)" clarifies the regional nucleic acid detection strategy in different scenarios. What is the core of this strategy and what role does it play in the future? "Daily Economic News" reporter asked questions at the press conference.

Wang Liping, a researcher at the China Centers for Disease Control and Prevention, answered a question from the reporter of the Daily Economic News that the nucleic acid detection strategy in the ninth edition of the ninth edition clarified the regional nucleic acid detection strategy in different scenarios and different scenarios, and clarified the epidemic situation. Later and regional nucleic acid detection strategies under normalized prevention and control.

Higher requirements for professional technology

On June 28, the ninth version of the prevention and control plan was announced.

The prevention and control plan proposes that after the epidemic, on the basis of epidemiological survey, the regional population size, whether the source of infection sources is clear, whether the risk of community transmission and the clear chain of the transmission chain occur in the integrated epidemic survey. The principle of grading classification determines the scope and frequency of regional nucleic acid detection. Arrange sinking cadres and community staff to knock on the door by households, find out the number of personnel, organize and guide regional personnel to participate in nucleic acid testing in batches to ensure that "inspections should be inspected, one household, no one is leaked."

At this press conference, Wang Liping said that after the epidemic, the following conditions were judged to meet the following conditions: the source of the infection was clear, the dissemination chain was clear, and the community dissemination was not required. Risk areas and personnel who meet and sometimes intersection of space conduct nucleic acid screening. For example, after the underwriting and judgment, the dissemination chain is unclear, the risk places and risks are large, and the risk personnel are liquidity. When there is a risk of diffusion in the epidemic, the regional full -staff nucleic acid detection is required. The scope of regional nucleic acid testing, testing strategies and termination conditions in cities, general cities, and rural areas.

"The core of this strategy is based on rapid flow adjustment, and the scientific and precise prevention and control concept based on the comprehensive research and judgment of regional population infection risks has put forward higher requirements for professional technology. Doing so can minimize the epidemic situation to the economy and society. The impact of development has protecting the safety of people's lives and health to the greatest extent. "Wang Liping said.

The existing vaccine and non -drug prevention and control measures are still valid

Recently, Omikon variants have spread around the world, causing widespread attention from all walks of life. Why is the plasticity of the mutant strains so strong? Dong Xiaoping, chief expert of the China Centers for Disease Control and Prevention, said that the variation of virus mutations, especially the RNA virus, is the basic characteristic of virus survival.

"When the virus host (crowd) generates a certain group immunity to a certain kind of strain through natural infection and vaccination, the virus will be mutated through the existing immune barrier through part of the virus. Infectious diseases often show one of the causes of increased periodic incidence. "Dong Xiaoping introduced.

Regarding the mutation of the new coronal virus, Dong Xiaoping said that the new crown virus is indeed a "smart" and "cunning" virus. In just two and a half years, multiple mutant strains have appeared, forming a number of popular peaks.

"Regarding the mutation of the new crown virus, most scholars believe that it will exist for a long time. The mutant strains of Omikon should not be the last mutant strain. The influence will be the focus of our long -term attention. "Dong Xiaoping emphasized.

Faced with the branches of Omikon's mutant BA.4 and BA.5, how should the public do a good job of protection? Dong Xiaoping said that for the branches of the Omikon mutant BA.4 and BA.5 sub -Asia, on the one hand, we must pay attention to its enhanced communication power and severe cases of severe illness/critical condition, especially in high -risk people. It is important to discover and control in time. On the other hand, there is no need to over -interpret and panic, the disease has not changed significantly, and the existing vaccine and non -drug prevention and control measures are still very effective.

"For personal protection, the first is to complete the foundation of the vaccine as much as possible and strengthen inoculation, especially the elderly and basic disease patients, to avoid serious clinical consequences. The second is to persist in doing normal personal protection." Dong Xiaoping said Essence
