Peter Hotez, who specializes in developing the vaccine, explained that “something different seems to be happening” with this variant. If, with other strains, the increase in covid-19 cases is proportional to the number of people showing symptoms, that has changed with BA.2.
“BA.2 is increasing everywhere in terms of the proportion of virus isolated” in diagnostic tests, the specialist said. “However, This translates to many different scenarios regarding the increase in cases‘, with groups of asymptomatic people and others with symptoms.
Another sign of this strain’s unpredictability is the fact that it has become more contagious in Austria, a country of only 8.9 million people and much stricter epidemiological restrictions, than in France or the United Kingdom, with a larger population and where Vaccination levels are equally high.
“I can’t see the consistency across countries”When ., Professor of Infectious Diseases John Swartzberg noted when Daily Beast.

However, there is no data to suggest that it is more lethal or that it increases the likelihood of developing serious disease.
As with other variants of the Micron family, vaccines are also less effective with BA.2. But a recent British study indicates that Revitalizing doses are able to restore protection levels.
BA.1, discovered in the fall of last year, was responsible for record numbers of new infections worldwide, becoming the most infectious respiratory virus ever. Weeks later, BA.2, which can be Up to 80 percent more portable.
The growth in cases of the BA.2 variant has been associated with the outbreak in China, as well as record numbers of cases in European countries, including Germany or the United Kingdom.
