The World Health Organization announced on Wednesday that the number of countries and regions in which the British Corona virus has mutated – one of 3 new strains being spread – rose to 70 on January 25; That’s an increase of 10 countries since January 19. Which Arab countries are affected by the new mutated Corona viruses?
We will quickly introduce you to the three new strains of the emerging corona virus, then we will move to the Arab countries that have reached them, then we will develop the details on the symptoms and the effectiveness of the vaccines.
British mutant dynasty
Name “B.7.1.1” (B.1.1.7).
The most important mutations it contains:
N501Y This mutation makes the virus more widespread.
“70del-69” (69-70del).
P681H.
South African mutant strain
Known by more than one name: “B.351.1” (B.1.351), and “V501.2” (501.V2).
The most important mutations it contains:
The N501Y.
K417N (K417N).
E484K This mutation is of great concern; Because it has properties of resistance to the most effective antibodies, which are secreted by the body of patients recovering from “Covid-19”.
Brazilian mutant strain
Name: “B.248.1.1” (B.1.1.248)
The most important mutations it contains
N501Y
E484K
Which dynasties have reached the Arab countries?
Arab countries that have received new strains of the Corona virus, as of January 27, according to the website “cov-lineages”, which specializes in monitoring strains of the Corona virus.
As of January 27, the British dynasty was registered in the following Arab countries: Jordan, Lebanon, United Arab Emirates, Oman, and Morocco.
As of January 27, the South African breed was registered in an Arab country, the United Arab Emirates.
As of January 27, the Brazilian breed had not been registered in any Arab country.
The spread of new breeds around the world
The most rapidly transmitted South African mutant continues to spread and has spread to 31 countries and regions, an increase from 8 countries, according to what the World Health Organization reported in its weekly epidemiological presentation .
As for the Brazilian mutation of the virus, it was detected in 6 new countries, bringing the total number to 8 countries.
Studies are being carried out all over the world, to determine the reasons why the British mutant is more contagious; But the mystery still surrounds the extent of its gravity.
On January 22, British Prime Minister Boris Johnson announced that the British mutant appeared to be more deadly; But scientists note the limited data, which indicates that it is between 30% and 40% more deadly than the original virus.
The World Health Organization is still hesitant in this regard, and said Wednesday that “these results are preliminary, and further analysis must be carried out.”
People of British ancestry cough more, but their sense of smell is less affected
And a British survey found that those who tested positive for the British strain of the Corona virus are more likely to develop symptoms of cough, sore throat and fatigue; But they are less likely to lose their sense of taste and smell.
This strain, discovered in south-eastern Britain in December, is believed to be spreading faster and may be linked to a higher death rate, although data indicates that increasing death rates are uncertain and not serious.
And the UK Office for National Statistics said other differences were seen between people infected with this strain and other patients with Covid-19.
He added, in an analysis of the characteristics of people with Covid-19 in England from November 15 to January 16, that loss of taste and smell is much less common in people with the new strain than people with the new strain. others.
He said other symptoms are more common in people in the British dynasty, and the most prominent among them are cough, sore throat, fatigue, muscle pain and high temperature.
He explained that there was no evidence of a difference in symptoms specific to the digestive system, shortness of breath or headache.

Pfizer and Biontech confirm their vaccine is effective against mutated British and South African versions
We conclude with the announcement by the companies “Pfizer” and “BioNTech” on Thursday, in a press release that their vaccine against “Covid-19” retains most of its effectiveness against the two major mutations of the emerging Corona virus, the Great Brittany and South Africa. .
In the statement, the two companies said that the “minor differences” found in tests comparing the original virus and the two new mutated versions “are unlikely to cause a significant decrease in the effectiveness of the virus.”
The statement said laboratory tests “did not indicate the need for a new vaccine to deal with emerging variables.”
At the same time, he stressed that the coalition “continues to monitor emerging variables and is ready to respond” in the event that any of these mutations are resistant to the vaccine.
