BREAKING! Four Delta Second Generation Variants Found In Thailand ie AY.4, AY.6, AY.10 and AY.12. More Than 27 Delta Sub-Variants Identified Globally!
Thailand’s Center For Medical Genomics has announced that 4 different second generation Delta variants
bearing unique mutations have been identified in Thailand so far in 14 different individuals.
According to local Thai experts, the Delta AY.4 variant
was found in a total of 9 gene sequencing cases in Thailand with Pathumthani province reporting 4 cases and one each case in the following provinces-Buriram, Kamphaeng Phet, Chiang Mai, Samut Prakan and Chonburi.
In Bangkok, one case each of the AY.6, AY.10 and AY.12 Delta variants
was detected while the province of Surat Thani reported 2 cases of the AY.12 variant

To date globally, a total of 27 different second and third generation Delta variants have been identified in the last 96 hours. 22 of these are named as Delta sub-species AY.1 to 22 while the rest are still being studied. In the naming nomenclature the Delta variant (B.1.617.2) sub-species AY.1 would be labeled as B.1.617.2.1
Global researchers are worried as some of these variants are possessing concerning mutations on them and more detailed studies are underway to understand how these mutations could cause differences in pathogenesis patterns and as well as enhancing viral fitness, virulence and also transmissibility.
Local Thai authorities also reported that the current predominance of the various VOCs or variants of concern in the country are as follows:
B.1.1.7 (alpha) 11%
B.1.351 (Beta) 14%
B.1.617.2 (Delta) 71%
It was also concerning that the Beta variant that was first identified in Africa was starting to increase in numbers especially in the Southern provinces in Thailand.
There is currently no data with regards to the behavior of each new emerging Delta variant sub-species or second generation variants with regards to the efficacy of the various current COVID-19 vaccines against them but a latest Japanese study warns that the Delta variant is evolving towards developing total vaccine resistance. https://www.thailandmedical.news/news/warning-the-delta-variant-is-mutating-rapidly,-sri-lanka-reports-4-new-delta-variants,-japanese-study-warns-about-vaccine-efficacy-and-ade-issues
Thailand Medical News will be providing more updates on the new emerging Delta variant sub-species or what we term as second or third generation Delta variants as there are a number of urgent studies currently underway.
