‘Mor Yong’ deciphers the African species of Covid get infected more easily Fear of vaccine-resistant virus Pointing to travelers from African countries need more supervision Prevent falling into Thailand
Date 26 Nov ’64 Prof. Dr. Yong Phuworawan Head of the Center of Specialization in Clinical Virology, Department of Pediatrics Faculty of Medicine Chulalongkorn University Post messages via facebook Yong Poovorawan It means that Covid-19 species B.1.1.529
This newly discovered virus It is a species found in South Africa. They are found outside of South Africa but are mostly from South Africa, such as Hong Kong.
The newly discovered species has approximately 50 genetic changes, and more than 30 of these occur on spikes or protein sprites.
a change in the location where antibodies are captured It is feared that this virus will become resistant to vaccines.
Importantly, the virus also changes the location of the enzyme in which the cleavage site is cleavage, especially converting it to alkaline amino acid (K = lysine), making it easier to cut with human furin enzyme Viruses easily enter cells. or more easily infected
For the non-structural protein 6 nsp6, there was a genetic deficiency. In this position it is another part that will help it spread more easily. As for the nucleocapsid Likewise, changes were observed similar to the alpha species.
However, this species also found a specific address in South Africa Population Movement Surveillance This will help reduce the spread of such species.
The rules of Thailand, especially test to go For those traveling from South Africa There must be more control measures. Probably not just test to go. To prevent the escape of such species into Thailand.
