1, Jin Dongyan's statement: We can draw a clear conclusion from the study of Omicron now, that is, it is actually produced to adapt to the resistant environment of human body.
Fact: Omicron is indeed a virus strain specializing in immune escape, and its pathogenicity is lower than that of previous strains. However, it is too biased to think that the evolution of COVID-19 must be in the direction of lower pathogenicity and higher immune escape ability.
2. Jin Dongyan's statement: Most people infected with Omicron show typical flu-like symptoms, which mainly affect the upper respiratory tract, just like the flu and the common cold. The proportion of asymptomatic infection and mild infection in Omicron increased obviously, accounting for more than 99.5% of the total infected people.
Fact: Although the infection of Omicron and flu symptoms partially overlap, there are significant differences. In particular, no large-scale sequelae of influenza have been observed, and the existence of COVID-19 sequelae has been confirmed by many studies.
3. Jin Dongyan said: COVID-19's disease is a self-limiting and self-healing disease. Now for the vast majority of people, more than 99.6% are self-limiting and self-healing.
Fact: It is too arbitrary to give a figure of 99.6% regardless of age, basic diseases and vaccination.
