1.Where were the BA.4 and BA.5 species discovered?
- BA.4 strains between January 10 and March 30, 2022, ending April 8. 41 cases of BA.4 have been identified in South Africa, two in Botswana, three in Denmark, England and Scotland. 1 per person
- The BA.5 strain ended on April 8. 27 people were infected in South Africa, three in Botswana, of which five of those BA.4 and BA.5 infected in this country were fully vaccinated. already and between the ages of 30-50 years
2. How dangerous are the BA.4 and BA.5 strains?
- There is no data to conclusively suggest that strains BA.4 and BA.5 can spread more rapidly or be more deadly than the original omikron strain.
3. Mutations of COVID BA.4 and BA.5
BA.4 and BA.5 share the same genetic code as BA.2, but have only two additional mutations from BA.2: L452R, which allows the virus to bind to human somatic cells to form a pathway for invasion. human genetic material The same is true for the Delta species, and the F486V location is rarely found in other species. But the absence of locus 69-70 found in BA.1 strains but absent in BA.2 strains, was found once more in BA.4 and BA.5 strains, favoring differentiation. More species than BA.2
4. Covid BA.4 and BA.5, do you want to escape the landscape?
- More studies are needed because of this mutation. May cause immune evasion in people who have been infected or have been fully vaccinated
- The WHO is closely monitoring the spread of strains BA.4 and BA.5, as well as strains BA.1 and BA.2, BA.3 and BA.1.1.
5. BA.4 and BA.5 with current vaccines
The WHO-approved coronavirus vaccine still prevents most people from getting serious illness or death. especially with the people who received the booster vaccination and booster vaccination For the elderly and co-morbid
6.Mutations of BA.4 and BA.5 can occur.
- Covid has been mutated since humans discovered it, including before. More mutations can occur than humans have always discovered.
- Most mutations usually have no effect on the virus. Many times weaken the virus. Sometimes it makes people weaker too.
- while the mutation rate can be accelerated under conditions such as uncontrolled epidemic Interactions between viruses among people infected with coronavirus.
