There are now reports of Japanese studies from various institutions. One of them is the University of Tokyo.
- BA.2 may not be a subspecies of Omikron. but should be counted as a new main species and using a new sequence of Greek alphabet names This opinion is consistent with Dr.D.Rhoads, a virologist at the University of Washington.
- from a study in hamsters BA.2 strains were found to cause more severe disease than BA.1 strains, worsening lung function. Dividing in the germ cells is faster. Therefore, it has the ability to spread the infection more easily.
However, how severe is the disease? It depends on 2 factors: the severity of the virus itself. and the level of human immunity
If BA.2 is really serious in humans, it doesn’t mean that will always cause more severe symptoms
Because now the number of people who have been vaccinated is more than 10 billion doses.
which will be an important factor that makes the symptoms less severe than the increased severity of the virus.
Humans will have to continue to study the characteristics of the 7th coronavirus that is constantly mutating.
cannot be trusted that Covid-19 (Covid-19) will become endemic or less violent until there is no big impact
because if the virus mutates in the direction contagious very resistant to vaccines and causing severe disease There will be a large outbreak around the world and Covid-19 will continue to exist. which no one knows how long
But there are some opportunities as well. at the mutation will allow the virus to spread quickly. but create less violence It will be the good fortune of humanity.
