Coronavirus deaths are on the rise in two-thirds of US states.
The winter surge in the incidence has led to the fact that the death toll has approached 400 thousand. All this is happening amid warnings about the emergence of a new, more contagious variant.
As Americans celebrated Martin Luther King Day on Monday, New York Governor Andrew Cuomo has called on federal authorities to ban travelers from countries where the new strains are spreading.
He mentioned new variants of the virus found in the UK, South Africa and Brazil.
Despite tremendous efforts to vaccinate Americans, the US vaccination campaign began unevenly. According to the latest federal data, about 31 million doses of vaccines have been shipped across the country, but less than 11 million people have received at least one dose.
