Genome Center reveals that omicron BA.1 in Thailand is extinct. BA.2 infected people continue to decline. While BA.4, BA.5 and BA.2.12.1 have not been found in the country yet
Today (5 May 65) Center for Medical Genomics, Faculty of Medicine Ramathibodi Hospital Mahidol University Posted a message saying Chance of re-infection with omikron subspecies “BA.4”, “BA.5” and “BA.2.12.1” (re-infection).
A report from scientists abroad found that from laboratory experiments, omicron sub-species (new sub-variant) BA.4, BA.5, and BA.2.12.1 are capable of human-to-human transmission. fast However, people infected with such subspecies tend to have mild symptoms. Close to the original Omicron
Professor Julie Swann of North Carolina State University, adviser to the US CDC on the epidemic. said the level of a person’s risk of re-infection The re-infection may depend on other factors, such as age, underlying health condition. and the time of last vaccination or last infection
If a person in their 60s received the booster vaccine four to six months ago, they may be at risk of reinfection with the new subspecies of omikron. And may have severe symptoms (severe). On the other hand, if a person is also 60 years old but has been previously infected with coronavirus or received a booster shot within 3-4 months if infected with the newly infected subspecies of omicron. emerges (new sub-variant) will have mild (mild) symptoms of COVID-19
Professor Alex Sigal, a virologist at the African Health Research Institute in South Africa. It states that people who have both been vaccinated and infected with the original omikron strain may have broader immunity that can combat the newly emerged omikron strain.
As for Thailand, the vaccination rate is up to 80%, which is higher than the UK, USA, Germany and India. Together with medical institutions across the country, randomly decoding the entire genome of the coronavirus, found that BA.1 is extinct. while the number of new BA.2 cases has continued to decline. The omicron subspecies BA.4, BA.5 and BA.2.12.1 have not been found in the country.
While BA.4 genome randomizations from both global samples and submissions are based on the global coronavirus database “GISAID”, there have been +667 cases, an estimated +2,652 outbreaks.
+318 random BA.5 genomes from all over the world and “GISAID” submissions have been completed, an estimated +1,000 outbreak.
Recently, there have been +10,233 random BA.2.12.1 genomes from all over the world and have been submitted to “GISAID”, and it is estimated that there will be an outbreak of more than +40,000 worldwide.
