Dr. Suphakit Sirilak, Director-General of the Department of Medical Sciences Revealed that the Omicron species is currently the main species spread in Thailand. from the ongoing situation of the COVID-19 epidemic leading to continuous evolution of mutations within the same species Born into various subspecies in the family. which has different mutation positions, the latest from the Department of Medical Sciences Together with the COVID-19 mutation tracking surveillance network in the country and tracking the strains of concern that may be encountered by travelers entering the country.
Doctors reveal that symptoms of COVID-19 are not severe, but they can be re-infected despite having previously been infected with Omicron.
The Ministry of Public Health keeps an eye on COVID “XBB- BN.1” after finding more patients. might dodge
During the past week, between 12-18 November 2022, the results of SNP/Deletion surveillance by RT-PCR method of 246 cases showed that in general, the proportion of BA.2.75 increased to 42.9% from the week. Before it had a proportion 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 was found. It is the strain BA.2.75.
From whole genome sequencing of samples in Thailand to date, strain BA.2.75 and its descendant BA.2.75 were found, such as BA.2.75.2, BA.2.75.5.1 (BN.1), BA. .2.75.1.2 (BL.2), more than 138 cases
In addition, nine cases of BQ.1 were found in America and Europe, and 13 cases of XBB were found in Singapore. and more easily infected
Director General, Department of Medical Sciences further said COVID-19 strain BA.2.75 was first detected in India in early May and has spread rapidly since then. Strain BA.2.75 carries one significant mutation, G446S, on its body-binding spiny protein. get in human cells and involves evading immunity. The rapid increase indicates that there might be an advantage in the epidemic. In Thailand, the first BA.2.75 was reported at the end of June 2022.
Omicron “XBB” infected in Singapore increased by 22%, no serious cases were found.
The Department of Medical Sciences continues to monitor and monitor the mutation of COVID-19 with the network continuously. And published on the international database GISAID regularly. to monitor the impact of subspecies of the species of concern that may lead to the spread of infection disease severity effectiveness of public health measures and other features related virus to provide information to support the design of treatment antiviral drug administration or synthetic antibodies However, public health measures Wearing a mask in crowded places, washing hands, can also cope with all strains of the outbreak. The booster vaccination can help reduce the severity of the infection.
