Assoc. Prof. Dr. Thira Woratanarat, Faculty of Medicine Chulalongkorn University posted on Facebook stating that BA.2.86 Update
last night Two cases of BA.2.86 have been reported in South Africa. which is a specimen collected since the end of July (24 July 2023)
Makes the total cases now 9 cases from 6 countries (if including Japan In case the report was found in the state of Virginia, America as a person traveling from Japan)
Thus, the distribution of BA.2.86 from various continents over the same period: Asia (Israel, Japan), Europe (Denmark, United Kingdom), America and Africa (South Africa).
And most cases have no travel history. indicated that it was a domestic infection
Emphasizes the trend that BA.2.86 has spread throughout the world. And there are likely to be more people infected now than reported.
Throughout the Omicron outbreak from 2022 to the present Virus mutations are usually gradual, in a step ladder pattern, with few changes in genetic loci. and result in changes in the performance of the virus, such as being more resistant to immunity but in a manner that is still predictable and assessable without seldom changing the violence as followed
But BA.2.86 is different from what it used to be. because there are many mutation positions This makes the virus very different from both the currently spreading strain XBB.x and its direct ancestor BA.2.
It is speculated that BA.2.86 may be caused by a chronic infection that incubates viral transformation. But still can’t confirm where it came from.
It will take another 2 weeks. The results of the evaluation of virus performance from various laboratories. The world will gradually come out to know each other.
Of the BA.2.86 virus mutation loci, there are 16 loci that existing knowledge suggests may lead to increased immune resistance.
With surveillance systems that exist around the world now The number of randomly tested specimens has decreased by 90% compared to when the Omicron outbreak began in early 2021, making it difficult to accurately assess the actual outbreak situation.
Hence, the number of reported cases detected continues to increase in such a short period of time. is therefore an important signal because it indicates the possibility that BA.2.86 will be an important enemy in the near future that could lead to a global outbreak
Should live a conscious life, not careless, always protect yourself.
wearing a mask correctly It will greatly reduce the risk.
