"If you look at the alpha strain, which was first discovered in the UK, then delta is 50% more infectious," TASS quoted her as saying.
According to her, under the attention of WHO is the lambda strain, which was first discovered in August 2020 in South America.
Vujnovic noted that "it is now being considered whether this strain is supplanting other strains, whether it has some characteristics that are more infectious."
She stated that the main thing now is to stop the transmission of the virus from person to person, as this allows the virus to mutate.
Vujnovic also said that WHO has recorded a stabilization and a slow decline in cases of coronavirus infection in Russia.
