Investing.com - The World Health Organization (WHO) is already studying a new variant of the coronavirus, called 'Mu', which was first identified in Colombia last January and already accounts for 39% of infections in that country.
Mu, scientifically known as B.1.621, has been classified as a "variant of interest" by the WHO.
The organization said the variant has "mutations that indicate a risk of resistance to vaccines" and emphasizes that more studies are needed to better analyze it.
However, he added that they are monitoring the variant as the Covid-19 pandemic evolves.
There is widespread concern about the emergence of new virus mutations as infection rates are increasing globally again, with the highly transmissible Delta variant taking hold, especially among the unvaccinated, and in regions where measures antivirus have relaxed.
Currently, Alpha is present in 193 countries and Delta in 170.
