What is the significance of high-frequency screening of oligonucleotide in Shanghai? Why should continuous nucleic acid detection be carried out in a sealed area?

The significance of high-frequency nucleic acid detection and screening in Shanghai lies in screening more positive infected people as soon as possible, and at the same time, it can end the epidemic in Shanghai as soon as possible. In addition, it is necessary to carry out continuous nucleic acid detection in the closed control area, because the virus has been confined to a specific area at present, and the remaining positive infected people can always be detected through multiple tests.

At present, Shanghai implements the epidemic prevention and control policy of high-frequency nucleic acid detection and screening. The epidemic situation in Shanghai has actually stabilized, and the number of asymptomatic and mild infections has been declining for several days, which means that the turning point of the epidemic situation in Shanghai has arrived. Many netizens praised this screening policy in Shanghai. After all, this kind of screening can screen out infected people in the community as soon as possible.

Significance of high-frequency subnucleotide screening in Shanghai: ending the epidemic as soon as possible

It is limited to carry out high-frequency screening of nucleic acid detection in Shanghai. First of all, we can screen out the remaining positive infected people as soon as possible, help them recover as soon as possible, and reduce community transmission. Secondly, the number of epidemic cases in Shanghai has begun to decline, which proves that the war between epidemic situation and prevention and control is about to start. As long as Shanghai strictly controls the quantity and accuracy of nucleic acid testing this time, the epidemic situation in Shanghai will soon end. Finally, if this epidemic can be ended as soon as possible, it is of practical significance for the college entrance examination in May and June, and it is necessary for students to take the exam under the regression line. The epidemic has dragged on for too long.

Continuous nucleic acid detection is needed in the sealed area: the virus has been confined to a specific area for elimination.

It is also necessary to carry out continuous nucleic acid detection in the sealed area. First of all, the longest incubation period of virus infection is 28 days, which means that the longest time from the beginning of infection to the end of infection is only 28 days, and now it has reached the final stage of virus incubation period. Secondly, most of the infected people in COVID-19 are concentrated in a certain area, and the virus has been trapped in a specific area in the currently closed control area. Continuous testing can quickly and accurately detect who is COVID-19-positive, which will also help to end the epidemic as soon as possible. At present, the frequency of testing and screening in COVID-19 accords with the current situation, and the number of new people in COVID-19 shows a sharp downward trend. As long as the nucleic acid screening is done as soon as possible and the infected person is cured as soon as possible, the epidemic will end as soon as possible.
