According to data released by the World Health Organization, the number of infected people registered worldwide has reached 130 million since the discovery of Omi kerong. It accounts for about 33% of the total number of COVID-19 cases.
Zhang Boli, an academician of the Chinese Academy of Engineering, told reporters that Aomi Kerong has a certain immune escape ability, and the concealment is also strong, because the initial symptoms are generally mild or asymptomatic, the patient's medical initiative is insufficient, it is difficult to find at the first time, and it is easier to spread or concentrate on outbreaks at multiple points. Mainland populations are generally sensitive to the Omiljun strain and have not yet formed a herd immune barrier against Omiljun virus.

Academician Zhang Boli believes that at present, there is no obvious trend of the end of the epidemic. Whether there will be new mutant strains that bypass the human immune system and cause severe diseases in the future is unknown, such as the new crown virus (BA.2), which is very similar to Omilon, which requires continuous caution.
In the face of the next stage of epidemic prevention and control, Academician Zhang Boli believes that we should adhere to the principle of dynamic zero clearance and make efforts to optimize accurate prevention and control measures.
The first is to speed up the approval of the marketing of the Omiljung vaccine, accelerate the relevant approval procedures, and carry out vaccine clinical trials in China with reference to the results of the mainland Omiljung vaccine test abroad. Universal vaccination can be carried out as a booster needle for sequential immunization, so that the whole population can passively form a herd immunity barrier of Theomex jung virus.
The second is to optimize the unified isolation time. There are different versions of entry isolation in different places, a large number of people need to be isolated to cause a certain burden on the normal operation of society and people's production and life, but most of them are within 14 days, the cost-effective ratio of increasing the isolation time is not high, it is recommended to optimize the isolation time, and the "14 + 7" policy can be implemented uniformly throughout the country, and the layers cannot be increased.
Third, the time of patients turning negative varies from individual to individual, but eventually they will turn negative and most of them are not contagious, which is speculated to be related to the weak autoimmune response of these patients. It is recommended that for patients with long-term nucleic acid non-negative and asymptomatic, antigen testing should be carried out after 14 days, such as negative antigen test, and can be discharged home for isolation and home health monitoring.
Fourth, most of the people who have regained their yang are not contagious, and no cases of re-infection with others after the revival have been found. The problem of Fuyang should still be paid attention to, and it is recommended that normal working life can be returned to after Fuyang isolation.
