The Yangtze River Daily Da Wuhan Client September 5th (Reporter Jiang Mengqing) What are the characteristics of this round of epidemic? How should citizens cooperate? How to prevent virus hidden transmission? On September 4th, Professor Wei Sheng, Professor Wei Sheng of the School of Public Health of Tongji Medical College of Huazhong University of Science and Technology, was interviewed by reporters from the Yangtze River Daily on these issues.

As of now, the results of the virus gene sequencing of the Municipal Centers for Disease Control and Prevention show that the new coronary virus genomic genome infection in the city's this round of epidemic cases is listed as the Omikon mutant plant BA.2.76.

Judging from the recent domestic and foreign population characteristics of Omikon mutation strains, Wei Sheng introduced that the spread of the strain showed two major characteristics, which can easily cause cases to grow rapidly in a short time.

Infectious and faster transmission. Wei Sheng pointed out that from the analysis of this epidemic, the interval between the transmission of Omikon mutation strains was about 2 days, and the latest research showed that the Omikon mutant strain can enter the host cells in about 2 minutes, and soon in the upper respiratory tract Showing index replication, and release mature virus particles in the infected cells after 12-24 hours, which is usually said to start "detoxification". Therefore, the Virus can be transmitted to Someone else.

The symptoms of infection are not obvious, and the concealment is stronger. The asymptomatic infection discovered by this epidemic accounts for relatively high. After the infection, most patients are not obviously clinical. Many people have no symptoms. Some are mainly lacking specific symptoms such as runny nose, sneezing, sore throat, etc., which leads to the increased difficulty of early discovery and early control of cases. It is easy to cause spread and spread. , Express or concentrate.

"In order to find the potential infection as much as possible, multiple rounds of nucleic acid testing in the short term is necessary." Wei Sheng said that although Omikon's incubation period was shortened, it was specific to the individual. Differential, this may cause nucleic acid detection. Although it has been infected, its virus load is insufficient, and nucleic acid detection cannot be screened. Therefore, multiple rounds of nucleic acid testing is needed to catch up with the speed of the spread of Omikon, so that all the potential infected people can be excreted.

In addition to the detection of nucleic acid, Wei Sheng believes that properly controlling the gathering and flow of social personnel is also a necessary means to quickly cut off the path of communication. "Omikon's infectious power is very strong. If you do not control the control of the society, you can basically double the number of infected people in two days. At the same time as multi -wheeled nucleic acid detection It is possible that Omikon's society is clear at a small price in the short term. "

Faced with Omikon BA.2.76 mutant strain is extremely hidden and contagious, Wei Sheng reminded the general public to actively cooperate with the requirements of the local epidemic prevention and control work, consciously do personal protection, and implement "temperature measurement, code scanning, wearing wearing, wearing, wearing Epidemic prevention measures such as masks, less clustering "; recently, there are places with large traffic and poor ventilation conditions as low as possible to reduce the chance of being infected; actively accepting nucleic acid testing and supporting the city's anti -epidemic situation with actual actions. At the same time, do a good job of self -health monitoring. Once there is a suspected symptom of new crown pneumonia such as fever, dry cough, sore throat, report to the local villages (communities) as soon as possible, and the village (community) will help contact the doctor in time.
