"We have different scenarios (the development of the situation. -

According to him, the virus will continue to evolve and mutate, which will threaten the health of the population in countries with weak health systems.

Ryan stressed that the world already has knowledge about the virus, as well as the means to contain it.

Earlier, WHO Director General Tedros Adhanom Ghebreyesus said that since the beginning of 2021, over 3.3 million people have died from coronavirus infection.
