For the BA.4 and BA.5 subspecies, there was a mutation concern at 452, the same as that previously occurred in the delta strain. But it’s too early to conclude that it’s as intense as Delta. The world is currently monitoring 3 strains, BA.4, BA.5, and BA.2.12.1, making more cases in the US, South Africa, Germany, Denmark.
In Thailand, there was 1 BA.5 in April, a Brazilian who traveled to Thailand. Now back home, BA.2.12 found 2 people, both Indians and Canadians. The problem is BA.2.12.1, which is a problem in the United States. Around the world, more than 10,000 people have been found, but now they are not found in Thailand. The mutation was different from BA.4 and BA.5, which was the change of the amino acid at position 452 from leucine to glutamine. This could allow the virus to evade more immunity.
Dr. Supakit also stated that BA.1 infections that can prevent BA.2, BA.4, and BA.5 infections, but if they are naturally infected and have vaccines, their immunity will not be reduced. a lot RT-PCR is now reduced in almost every country, but laboratory surveillance systems still detect the strain. by decoding the whole genetic In Thailand, check at least 500 people per week, ready to deal with emergency situations. and has been urged to focus on collecting samples in people entering the country and those who are seriously ill to find out whether it is caused by a new species or not Ask people to be confident in the country’s detection system. that can be prevented in a timely manner Don’t panic.
