BA.2 Variant Causes More Serious Diseases

According to the weekly report published by the World Health Organization (WHO/WHO), the BA.2 variant of the Omicron mutation of the COVID-19 virus has been detected in 10 different countries. raid It has been stated that it has become; The ratio of BA.2, which is stated to be more contagious than the BA.1 variant of Omicron, in Omicron cases 21.09 percent’A rise was recorded.

Thereupon, the curiosity and concern for BA.2, a sub-variant of the Omicron variant, naturally increased. In a recent study on BA.2 in Japan, in addition to spreading faster than other mutations, BA.2 is much more serious illness has been found to cause

BA.2 resistant to some treatments

The BA.2 variant, which has been scrutinized in detail together with laboratory experiments, shows the drug and precautionary methods taken against the COVID-19 virus. ineffective was stated to be possible. Accordingly, in the study, it was found that BA.2, similar to Omicron, did not benefit from the immunity and protection provided by vaccines. substantially reported to be unaffected.

Effect of booster COVID-19 vaccine dose on 74 percent If the variant, which is stated to be against Omicron, is against some treatments, such as sotrovimab, a monoclonal antibody used in the fight against Omicron. resistant was recorded.

Making evaluations about the research, the head of the microbiology department of the Cleveland Clinic in Ohio, USA, Dr. Daniel Rhoads, on the other hand, found that BA.2 was better than BA.1. a bad virus stating that it could be “It can be transmitted more and cause worse disease” used the phrases.

30 to 50 percent more contagious, according to Omicron

Researcher Kei Sato from the University of Tokyo, who led the study, said that their findings are considered as a sub-variant of BA.2 Omicron. not to be He emphasized that it is a proof that there is a need for a closer follow-up of the variant. In addition, Sato, BA.2’s “Secret Omicron” He also pointed out that the reason why it was defined as an S-gene target error was that BA.2 did not appear as an S-gene target error in PCR tests, just like Omicron.

The BA.2 variant, which is stated to have more mutations and different gene changes than Omicron, compared to the virus that caused the original COVID-19, is currently in 74 countries detected and the contagion power according to Omicron. 30 to 50 percent More is known.
