American expert warns Omicron is not the last worrying strain

The director of the US National Institutes of Health Collins warned that nCoV can continue to mutate and Omicron is not the last strain to cause many concerns.

“It’s almost certain that this won’t be the last strain to cause a lot of attention and concern,” National Institutes of Health (NIH) director Francis Collins said on December 5, referring to the Omicron strain and saying that This strain developed from a person with a weakened immune system.

Collins added that Omicron is the strain with the largest number of mutations ever, with at least 50 mutations, of which 32 are on the spike protein, helping the virus to more easily enter the cell or avoid Avoid the immune system.

“If we don’t have adequate immunity globally, we’ll continue to record mutations and we’ll have to use a few other letters of the Greek alphabet,” warned the NIH director. .

South African expert Tulio de Oliveira, who was dubbed the “hunter” of the virus, previously also suggested that Omicron had been incubated in the body of people with severe immunodeficiency, such as HIV infection.

Omicron is a new strain of nCoV that was first detected in Botswana on 11/11 and reported by South Africa to the World Health Organization (WHO) on November 24. The WHO has classified Omicron as a variant of concern, although it is not clear whether this strain could reduce vaccine effectiveness or increase the risk of severe disease.

Omicron is present in more than 40 countries, including the US. Many countries have decided to tighten border controls, especially with southern African countries, in the context of Omicron infections continuously being recorded in countries.
