…Update research on BA.2

Chen LL and team from Hong Kong A comparative study of neutralizing antibody immune responses to the Omicron strains of COVID-19 BA.2 versus BA.1.

Immune resistance was found to be somewhat less likely to BA.2 than to BA.1.

Observations obtained from the results of this research reflect that The epidemic of BA.2 that is more sensitive than the original BA.1 Probably caused by other factors. Non-immune resistance, i.e. the efficacy of the virus itself to spread and/or infect more easily. or other factors about people, behavior, etc.

Review the knowledge we currently have about BA.2.

One is about 30% faster than BA.1.

Second, the infected person had about twice the viral load in the throat than BA.1.

Third, it binds to ACE2 receptors on the cell surface better than BA.1.

Fourth, the secondary attack rate is higher than BA.1

Fifth, the period from the first day the first infected person develops symptoms. to people infected with symptoms (serial interval) shorter than BA.1

Sixth, immune resistance appears to be somewhat less than BA.1.

…Currently, in Thailand, the epidemic continues to spread throughout the country. Most of them are infected from daily life. Both at work, at home, banquets, weddings, funerals, ordination as well as places that are crowded, crowded, poorly ventilated. and it is very clear while eating and drinking with others because it is not self-defense
