First, it is difficult for Omicron to completely destroy Omik. After becoming the mainstream virus strain in COVID-19, Omicrovirus continued to mutate, but its pathogenicity decreased and its infectivity increased. Some experts believe that it is impossible to completely eliminate Omicron, but hope that its toxicity will become less and less as time goes on.
Now the incubation period of Omik virus has been significantly shortened, and there are not many severe cases, most of which are mild or asymptomatic, so the isolation time must be shortened. With the change of virus and epidemic situation, the expert's treatment plan will also change and become more scientific and accurate. According to the experience of virology in the past, most viruses are stored with humans.
This kind of * * * exists because of its low morbidity and mortality and relatively easy treatment. So it has existed in human society for a long time, and Omicron also has this trend in its development.
Second, the Omicrovirus Omicrovirus is a variant of the new crown pneumonia. Omicron is a mutant of 202 1, 1 1, which has strong concealment and infectivity. Omicron is very latent, its clinical symptoms are not obvious, and it is not easy to be detected by the outside world. At the same time, some people are not sensitive to COVID-19 nucleic acid test, and may have false negative.
Because of the high concealment and spread of Omicron, residents living in high-risk areas of Omicron should wear masks, wash their hands frequently and take preventive measures. According to epidemiological investigation and laboratory gene sequencing analysis, the outbreak of Omicron was caused by Omicron BF.7 mutant, which is the abbreviation of BA.5.2. 1.7 in Omicron.
Omicron BF.7 mutant spreads quickly and has strong concealment, and the average passage time of the virus is about 2 days. After being infected by human body, Omicron BF.7 mutant will have symptoms such as high fever, persistent cough, general pain, headache, sore throat, olfactory change, loss of appetite and so on.
