What are the new features of current popular viruses?
At present, the main popular COVID-19 virus is Omicron strain, which has the characteristics of high concealment and strong infectivity. However, the pathogenicity of the virus has weakened, and most of the infected people are mild or asymptomatic. Ordinary type, heavy type and critical type are less.
