And the “CNN” website confirmed, “The BA.2 mutant is more transmissible than the original Omicron mutant, BA.1, according to early studies from Britain and Denmark, and this “mutated mutant” is the reason why about 1 in 5 cases of Covid-19 are infected. around the world, according to the World Health Organization.
Even with the decline in coronavirus cases worldwide, the proportion of BA.2 cases is increasing.
The “mutated mutant” outperforms the original Omicron in at least 43 countries, raising fears of another devastating pandemic wave.
“So far, I don’t think we need to sound the alarm globally,” said Dan Baruch, director of the Center for Virus and Vaccine Research at Beth Israel Medical Center in Boston. “But I think we need to pay attention to BA.2 because it appears to have a growth advantage over BA.2.” BA.1″.
mutated mutated
Like a mutant BA.1 The original Omicron contains BA.2 also has features that help it escape some immunity from vaccines and from most monoclonal antibody therapies, although newer boosters improve personal protection.
New studies now offer some reassurance that while BA.2 may outperform its genetic “cousin”, it is unlikely to lead to greater numbers of hospitalizations and deaths.
“My assessment, from speaking to a number of my colleagues who are already doing genetic surveillance, is that BA.2 It does kind of creep in terms of numbers, but it’s not as meteorically fast as in the original Omicron mutant.”
The low prevalence of the second omicron mutant comes from, because in many countries such as the US, Britain and Denmark, BA.2 hit speed bumps left by BA.1, which was already highly contagious.
“Very soon after the initial BA.1 peak, you had a lot of people who were vaccinated or boosted … and the antibodies that protect against infection spread,” Rasmussen said.
second injury
The second new study, from the Danish Serum Statins Institute, looked at the risk of infection again with corona, in the event of a BA.2 attack, after recovery from the first infection that was via the original omicron or delta mutant.
The study found that people who have recently been infected with corona caused by omicron or delta, can be infected again by the emerging mutant of omicron, but such cases are uncommon, affecting mostly those who have not been vaccinated and often lead to mild symptoms.
The BA.2 . mutant is considered The first mutant responsible for Corona injuries in Denmark. The new mutant outperformed the original Omicron mutant since the second week of last January.
