Dr. Anan Chongkaewwatana posted information on the subspecies of omicron BA.2.75 after being found in India. And there are reports found in the United Kingdom, the United States, indicating that the epidemic trend is faster than BA.5
On July 3, 2022, Dr. Anan Chongkaewwatana, Director of Animal Health and Management Innovation Research Group National Center for Genetic Engineering and Biotechnology (Biotech), National Science and Technology Development Agency (NSTDA) posted a message via Facebook “Anan Jongkaewwattana” about COVID-19 strain BA.2.75. that
It is expected that soon more BA.2.75 will be mentioned in the media. Currently, most of the virus strains are found in India. But it has been found that many countries have reported the virus, such as the United Kingdom and the United States. The virus has attracted attention for two main reasons:
- It is BA.2 with 9 additional mutations on the spike protein (compared to BA4/BA5), but since position 493 (R493Q) is a reversal from omikron. go like the original species causing some people to count as 8 positions due to more than normal changes Specifically, position 446, which shifts from G (Glycine) to S (Serine) G446S, has been mentioned as a location that allows the virus to escape more antibody binding.
- Data on the number of virus samples cracked in India. A significant increase in the number of this species was observed. especially in Maharashtra which is the birthplace of species like the Delta before There have been some attempts to compare BA.2.75’s ability with BA.5 to spread. BA.2.75 is likely to run faster. but since there are not many samples The credibility of the information is still less. There is no issue of the severity of this infection coming out. will have to watch closely
