“With a virus that truly has no borders, travel restrictions that isolate any country or region are unfair and ineffective,” the UN Secretary General wrote on his Twitter account.

He urged all governments to consider retesting for tourists, along with other appropriate and more effective measures to counter the virus, instead of this method.

Earlier, Anatoly Altstein, MD, virologist, on the air of the NSN expressed the opinion that the new omicron coronavirus strain does not yet represent any relevance from the point of view of vaccination of people.
