The Centre for Medical Genomics (CMG) at Ramathibodi Hospital has predicted the more transmissible BA.4 and BA.5 Omicron subvariants are likely to become dominant strains in Thailand next month.
Dr Wasun Chantratita, who heads the centre, said 11 cases of BA.4 and 18 cases of BA.5 were detected in the kingdom between June 7 and 24.
The number of cases corresponds with global trends, with the subvariants expected to take over as the dominant strains in the world, he said.
