“SARS-CoV-2 continues to change – to have new sub-variants of Omicron. In the UK, a new wave is believed to be due to two sub-variants of Omicron – BA.4 and BA.5. Even in highly vaccinated countries subvariants manage to bypass the immune response in vaccinated and ill people, “said Plovdiv epidemiologist Dr. Hristiana Batselova in” The Day Begins. “
She clarified that in Bulgaria at this stage the registered new cases are not many.
“Most people are not tested if they do not need hospital treatment or for some other reason,” added Dr. Hristiana Batselova.
According to her, when the waves of newly infected people in Western Europe start, they come to Bulgaria in about a month.
“There is evidence that sub-variants of Omicron BA.4 and BA.5 affect the lungs and can cause severe illness,” explained Dr. Batselova.
According to her, people should not calm down because it is still a pandemic.
