Nine cases of BQ.1 have been detected in Thailand, while XBB has detected 13 – higher infections in the country.

On November 22, 2022, Dr. Supakit Sirilak, Director General of the Department of Medical Sciences Revealing the situation of the strains of the COVID-19 virus in Thailand since the beginning of 2022, Delta strains have been replaced by Omicron strains, including BA.1, BA. 2, BA.4, BA.5 and other subspecies Omicron strains are currently the main types distributed in Thailand. of the ongoing COVID-19 epidemic situation leading to the continuous evolution of mutations within the same species Born into different subspecies in the family. which have different mutant positions

However, the latest information from the Department of Medical Sciences along with a surveillance network tracking the mutations of COVID-19 in the country and following the strains of anxiety that can be detected by travelers entering the country During last week, between 12-18 November 2022, the PCE/Elimination surveillance results by RT-PCR method of 246 cases showed that, in general, the proportion of BA.2.75 increased to 42.9% since the week. a share of 23.6% and when separated by group, it was found that the majority tended to increase among those infected in the country from 23.2% to 43.9%, especially in the areas of health zones 2, 6, 11 and 12 where more than half of the proportion found is strain BA.2.75.

From whole genome sequencing of samples in Thailand to date, the strain BA.2.75 and its descendant BA.2.75 such as BA.2.75.2, BA.2.75.5.1 (BN.1), BA.2.75.1.2 (BL. 2), more than 138 cases

Nine cases of BQ.1 were found in America and Europe, while 13 cases of XBB were found in Singapore, with no indication of the severity of the mutation. But it could make it easier to spread and infect.

Nine cases of BQ.1 have been detected in Thailand, while XBB has detected 13 - higher infections in the country.

The Director General of the Department of Medical Sciences further said that the BA.2.75 strain of COVID-19 was first detected in India in early May. The BA.2.75 strain carries one significant mutation, G446S, on the spiked protein, which binds to a receptor in human cells. and it means avoiding immunity. The rapid increase indicates that there may be an upside to the epidemic. In Thailand, the first BA.2.75 was reported at the end of June 2022.

“The Department of Medical Sciences continues to monitor the mutations of COVID-19. join the network continuously And is published on the international database GISAID regularly. monitoring the impact of a subspecies of the species of concern that could lead to the spread of infection the severity of the disease the effectiveness of public health measures and other characteristics of associated virus to provide information to support treatment design administration of antiviral drugs or synthetic antibodies.”

Dr. Supakit Said that at the end public health measures Wearing a mask in crowded places, washing hands, can also cope with all types of cases. And booster vaccination can help reduce the severity of the infection.
