The coronavirus mutation identified in the United Kingdom is present in 50 countries, according to the World Health Organization (WHO), and the variant located in South Africa was detected in another 20 territories.
In America, Brazil, Canada, Chile, Ecuador, Jamaica, Mexico, Peru and the United States reported the variant from the United Kingdom, while Brazil and Canada found the variant from South Africa in their laboratory samples, according to Sylvain Aldighieri, incident manager for covid-19 at the Pan American Health Organization (PAHO).
WHO also warned that a third “worrying variant” found in Japan may have an impact in the immune response and needs to be further investigated.

“The more the SARS-CoV-2 virus spreads, the more chances it has to change. If there are high levels of transmission, we have to think that more variants will emerge, ”said the WHO.
Since it was communicated to WHO on December 14, the British variant VOC 202012/01 has been detected in 50 countries, territories and areas, it said.
The analysis of the results show that the age and sex of the infected people are similar to the other variants. The contact tracing data also reveals “higher transmissibility (secondary attack rate) when the index case has the variant strain.”
This new variant does not seem to cause more severe diseases, the rapid increase in the number of cases has put the health system under pressure
The mutation detected in South Africa, called 501Y.V2, reported on December 18, is now found in 20 countries, territories and areas, the agency added.
“Based on preliminary and ongoing investigations in South Africa, it is possible that the 501Y.V2 variant is more transmissible than previously circulating variants in South Africa”, Specified the weekly WHO report.

“Although this new variant does not appear to cause more severe disease, the rapid increase in the number of cases has put the health system under pressure ”.
The spread of both variants is underestimated, the WHO warned, due to data distortion caused by countries with the ability to analyze virus sequencing.
