Shanghai launched a new round of nucleic acid testing or antigen testing yesterday. What is the significance of this round of screening in Shanghai? How to understand this number scientifically?
From April 1st, Shanghai began the first round of city-wide nucleic acid screening, with the aim of passing the screening to the greatest extent possible. , Screen out possible latent infections as quickly as possible. Shanghai, in line with the four principles of inspection, quarantine, collection, and treatment, should find out the source of infection and the source of infection as soon as possible, and treat and isolate them as soon as possible, so as to effectively manage and Control, block the source of transmission, the source of infection, and cut off the chain of transmission. This is extremely critical and extremely effective in respiratory infectious diseases.
On April 6, Shanghai launched a new round of nucleic acid testing or antigen testing. It is understood that the new round of testing is mainly for areas where no positive cases have been found before, and antigen testing is used for screening. If the antigen test is positive, a single tube of nucleic acid will be confirmed immediately, and the possible infected persons in the low-risk area will be screened out as efficiently and in a timely manner as possible, and the society in Shanghai will be cleared to the greatest extent and as quickly as possible.
Qu Jieming, Secretary of the Party Committee of Shanghai Ruijin Hospital, said in an interview that the new crown epidemic was mainly caused by the mutant strain of Omicron. The Omicron variant has a very strong ability to replicate. More than 95% of the respiratory tract infections caused by the Omicron variant, especially in Shanghai, are basically asymptomatic infections. A full-scale test can immediately hide the infection. Screening out asymptomatic infections in the population. With the launch of nucleic acid for all staff on April 1, the number of newly infected people has been increasing in recent days, which is in line with the characteristics of active screening and early detection.
Qu Jieming reminded the vast number of Shanghai citizens not to panic, it is still a platform period for the active detection of infectious diseases, and it is normal for the number of short-term cases to increase significantly.
