Most recently, Dr. Supakit Sirilak, Director-General of the Department of Medical Sciences Revealing information about the discovery of a hybrid covid-19 species called Hybrid from the surveillance of the Covid-19 species. Between March 26 and April 1, 2022, a total of 1,933 cases were found to be 99.84% omikron, with an increase of 92.2% in the subspecies of BA.2 and in the near future, BA.1 may be cured. Go, mutation is the nature of the virus. Many infections have the potential to mutate.
“Mixed infection with two or more strains in a single person (Mixed Infection) has the potential to fertilize a new, or “hybrid” type with an “X” prefixed summoning system. Currently there are approximately 17 animals. From XA to XS, but in the global surveillance system GISAID, 3 real hybrids are recognized: XA, XB and XC.” Dr Supakit explained He said that the virus found since XD and below is still in the process of analyzing more data before it can be concluded that it is a new one.
Director-General of the Department of Medical Sciences also said that Many hybrids are derived from the BA.1+BA.2 omicron subspecies such as XE XG XH XJ and are found in different countries. But they had to be given different names because they had different genetic codes and mismatched locations.
“The Department of Medical Sciences has genetically decrypted to monitor 500-600 strains a week, and found that one case is similar to “XJ” first found in Finland, which is a combination of BA.1+BA.2. Dr Supakit said
Dr Supakit also said that For the XJ strain, there is no information on how fast or severe transmission is possible. Because preliminary, it is necessary to detect the location of the change in the genetic code first and consider whether the changing position has a chance to hide, exacerbate, or spread more quickly.
On the side, Dr. Throne Upaphong, Deputy Director-General of the Department of Medical Sciences provide additional information that Patients diagnosed with a hybrid strain A 34-year-old Thai male patient, a transport worker. which has the opportunity to meet many people This makes it possible to infect two or more strains in one person easily. and have the opportunity to breed as a new
“The sample was sent from a hospital in Bangkok, where the virus was detected since February 22, 2022. There is a history of two injections of vaccination, and now this patient has recovered normally,” said Dr. Throne, adding that Department of Medical Sciences has sent data to GISAID, a global database system GISAID (Global Initiative on Sharing Avian Influenza Data, which started from sharing global bird flu data.
Currently, the GISAID database is a system for sharing all Influenza virus genetic code and Coronavirus genetic code, including SARS-COV-2 that causes COVID-19. It collects epidemiological data. to study the evolution of the virus
“We will have to wait a lot of data analysis before deciding whether it is a real hybrid or not. and may or may not use the name XJ,” said the deputy director-general of the Department of Medical Sciences.
Finally, the Director-General of the Department of Medical Sciences emphasized that people still do not have to worry about hybrid species. As for the BA.2 subspecies that are currently emerging has a rapid spread making it more likely to be infected It is best to avoid risky behaviors and strictly protect yourself. especially about wearing masks and avoid eating together, including having to get a booster shot to boost immunity Because Omicron is now spread easily. high chance of infection You must protect yourself strictly.
