Dr. Teera warns that Omicron EG.5.1 may have a serious epidemic towards the end of the year because it has more ability to avoid immunity than previous strains.
Today (6 Aug.) Assoc. Prof. Dr. Thira Worathanarat, Faculty of Medicine Chulalongkorn University Posted on Facebook Thira Woratanarat came out to post a message about “Omicron EG.5.1” that is expected to be strong at the end of the year. After finding out that now the number of infections worldwide is rising overtaking other subspecies.
“Regarding EG.5.1, a favorite horse that may lead to an outbreak at the end of this year.
It is a mutated subspecies from XBB.1.9.2, also known as XBB.1.9.2. XBB.1.9.2.5.1
In comparison, it was like a great-grandson of XBB and a great-grandson of XBB.1.9 and something like that.
What makes EG.5.1 a global concern now is that The detection rate is increasing faster than the different species. Previous outbreaks, including XBB.1.5, XBB.1.16, as well as XBB.1.9.1/1.9.2
Until this moment, the information became clearer and clearer. that is as expected
The latest data from the US CDC estimates that as of August 5, 2023, the Omicron subspecies EG.5.1 had the highest share of detections at 17.3%, surpassing other subspecies such as XBB.1.16 (15.6%), XBB.2.3 (11.2%). ), XBB.1.5 (10.3%)
While the UK HSA released its report on August 2, It suggests that EG.5.1 already accounts for 12% of detections in the UK and is on the rise.
Overall, it is now found around 20% in Asia, 10% in Europe, 7% in North America. (except in the United States, which is as high as 17.3%)
…Why did EG.5.1 lead the others?
Last night’s data from Cao YR, Peking University. This suggests that EG.5.1 is genetically modified at F456L, which makes it more capable of immune evasion than previous strains.
interesting is Even immunogenic testing in the sera of people previously infected with the XBB strain was also found to be immune-resistant.
In addition, Cao YR has also found that various subspecies happened The change in position F456L in conjunction with L455F also requires monitoring. because it has the potential to make both more resistant to immunity and more tightly binds to the ACE2 receptor on the target cell surface. This may make it more likely to become infected and spread the infection. or more severe illness
However, the one that is most notable right now is EG.5.1 because it is clearly more widespread worldwide.
…Factors, including viruses that improve performance In addition to the conditions that we tend to tend to like other countries in 6-10 weeks and the schedule of activities and festivals at the end of the year
after October There may be a chance that it will erupt.
Should live a daily life consciously, not carelessly, always protect yourself.
beware of crowded poor ventilation
Do not share food with other people outside the home.
wearing a mask correctly It will greatly reduce the risk.
Have a nice weekend.”
