Mr. Tuliu G. Olivera Brazilian scientist Director of the Center for Epidemic Response and Innovation in South Africa The new omicron substituents of the 2019 coronavirus, BA.4 and BA.5, are more likely to evade vaccines and natural immunity from previous infections, according to reports. And it is easier to infect than the BA.2 subspecies.
Mr. G Olivera said it was easier to dodge. This means that after this, the number of infected people will increase. And now, up to 70% of new cases are infected with the BA.4 and BA.5 subspecies.
The official number of coronavirus cases had actually jumped to 4,146 on Thursday, compared with 581 on March 28.
Mr G Olivera added that although it was more easily infected. But this does not mean that it will increase the rate of morbidity requiring hospitalization or mortality.
