The variants of Covid-19, detected in recent weeks, are now circulating in various countries around the world. These new strains are of particular concern to health authorities, particularly the World Health Organization (WHO). According to the UN agency, the three mutations of the virus pose a danger each in its own way.
To date, three mutations of the Sars-CoV-2 virus have been identified. The first was seen in the United Kingdom, specifically in the southeast of England. This variant has spread rapidly across the country in recent weeks. The World Health Organization (WHO) was informed of this discovery on December 14.
The second strain has been detected in South Africa. It was first reported on December 18 to the UN agency.
The last mutation was found in Japan. The country informed the WHO of the appearance of this new variant of the virus, directly from Brazil, on January 10.
The British and South African variants have already been developed in several countries. According to the WHO, the English strain is currently circulating in 50 states and the South African variant has been found in 20 countries. These three strains have generated concern among many governments in recent weeks. These mutations are of particular concern to the WHO, which met urgently on January 14 to discuss these new variants of the coronavirus.
Covid-19: "some variants of the virus appear to have stronger transmissibility"
"The more the virus spreads, the more likely it is to transform. And above all, certain variants of the virus seem to have a stronger transmissibility," said WHO Director-General Tedros Adhanom Ghebreyesus, during the Covid update. - January 19, 11.
He explained that this can lead to an increase in the number of cases and hospitalizations, which is problematic for health workers and hospitals "that are already close to breaking point." "High levels of contamination mean that we should expect more variants to emerge," the UN agency said.
"Based on preliminary and ongoing research in South Africa, it is possible that this variant is more transmissible than variants previously circulating in South Africa," the WHO said in its weekly bulletin published on 12 January. "Furthermore, while this new variant does not appear to cause a more severe form of the disease, the rapid increase in the number of observed cases has put health systems under pressure," the organization said.
