And, unfortunately, it is even more dangerous – it causes a severe course of the disease, and a lot people died after this disease. Now there is a variant of “Omicron”, – said Komissarenko.

There are many more mutations in the Omicron strain than in the others. Scientists count more than 50 of them. Komisarenko noted that Omicron infects human cells three times more. That is why this mutation will supplant even Delta.

At the same time, the scientist emphasized that Omicron infection is easier, and the lethality as a result of infection is lower than in the case of Delta.

As UNIAN reported earlier, the Omicron coronavirus strain was first discovered in early November in southern Africa. On December 14, WHO announced that this strain is rapidly taking over the world.

According to the Medical Press, scientists from Hong Kong have proven that vaccination with vaccines from Pfizer-BioNTech and Coronavac will not help in the opposition to Omicron.

On December 18, Minister of Health Protection Viktor Lyashko said that the first case of infection with the Omicron strain was recorded in Ukraine.
