Bangkok, July 14-Department of Science reveals that Thailand has found 5 cases of COVID-19 of the EG.5.1 strain, yet no data on the severity
Dr. Supakit Sirilak, Director-General of the Department of Medical Sciences, said that in the event that there is news about the COVID-19 strain EG.5.1 spreading faster than XBB.1.16, the Department of Medical Sciences Please provide additional information as follows: EG.5.1 or XBB.220.127.116.11.1 It is a subspecies of the omicron XBB.1.9.2.*, with additional mutants on the spiny protein S:F456L (the amino acid at position 456 changes from phenylalanine to leucine) and S:. Q52H (the amino acid at position 52 is changed from glutamine to histidine). Infection rates in the past 3 months Overall, it was found to be 45% higher than XBB.1.16* hybrids.
Situation in Asia Between June 4 and July 4, 2023, XBB.1.16 was found to be a strain. The most common was 13.71%, followed by XBB.1.9.1, 8.68%, and EG.5.1, 7.33%.
The situation of the EG.5.1 strain worldwide is based on the central GISAID database divided by region as follows: Asia 1,385 cases, Europe 203 cases, Oceania 35 cases, North America 360 cases, Central America 4 cases and South America 1 case (data as of 10 July 2023).
The EG.5.1 strain in Asia was reported from 11 countries in descending order: China, South Korea, Japan, Singapore, Hong Kong, Israel, Laos, Indonesia, Taiwan, Thailand and India. In Thailand, five cases of EG.5.1 were first reported in April 2023. 1 case, 3 cases in May 2023 and 1 case in June 2023. Information on increasing violence has not yet been found.
Dr. Supakit continued that the current overall situation found that XBB.1.16 is the main strain of the epidemic in Thailand. In the past week between 17-23 June 2023, 74 cases of COVID-19 pathogen transcription results were found to be XBB.* hybrids, 73 cases (including XBB.1 , XBB.1.9 , XBB .2.3 , XBB.1.5 , XBB.1.16 ) accounted for 98.6% and XBL hybrid (XBB.1.5 mixed with BA.2.75 ) 1 case. The proportion of species examined this week, the top two were XBB.1.16 hybrids. and XBB.1.9.1* accounted for 56.76% and 16.22% respectively. No EG.5.1 was found this week.
Currently, the World Health Organization focuses on tracking 8 Omicron strains based on data. An increase in prevalence or an increase rate advantage compared to other strains. and mutations in positions associated with pathogenic advantage, i.e. two Variants of Interest (VOI), i.e. XBB.1.5* and XBB.1.16*; Variants under monitoring (VUM) 6, namely BA.2.75 , CH.1.1 , XBB , XBB.1.9.1 , XBB.1.9.2* and XBB.2.3*
The Department of Medical Sciences continues to monitor changes in strains of the pathogen causing COVID-19. continually especially in cases with severe symptoms or death," Dr. Supakit Said.-Thai News Agency
