The sudden severity of the new crown outbreak may be related to the mutation of the new crown virus, the high viability of the new crown virus, and the lax awareness of prevention and control.
1. New coronavirus mutation: more infectious and hidden, the current epidemic of new coronavirus in our country is mainly for the Omicron variant BA.2 evolutionary branch, the transmission capacity of this mutant strain than the original strain of Omicron about 30% higher. Moreover, most of the infections caused are mild or asymptomatic infections, which are more covert, thus leading to the sudden seriousness of the new crown epidemic.
2. The survival ability of the new crown virus is strong: the new crown virus can survive in low, normal and high temperatures, and can continue to survive after leaving the host, which is also the reason why the new crown outbreak suddenly became serious.
3. Prevention and control of the awareness of laxity: some areas of the epidemic prevention and control of the awareness of laxity, prevention and control measures are not in place, do not wear masks, will lead to the new crown epidemic suddenly serious phenomenon.
Suggestions usually travel good protective measures, avoid going to high-risk areas, with the work of medical personnel, will certainly overcome the epidemic.
