Active since January, when the first cases of this variant of the coronavirus were detected in Colombia, Mu has been a new litmus test in the fight against the pandemic in recent days. And it is that, despite not being of special importance in recent months, this week as “interest under surveillance”.
While Spain, specifically, and the rest of the world, in general, puts its efforts into reducing infections by the Delta variant, which already accounts for 90% of cases in many regions, a new variant of the coronavirus has spread, warning of its dangerousness. Mu, born in Colombia, from South Africa, in those that most threaten the future.
And it is that Mu, or B.1.621. Due to its scientific name, it has mutations that can escape vaccines, so it would be resistant to the latest inoculations, causing as much concern as Delta has already achieved. Of course, even with many investigations ahead, since its range of action is around 0.1%, it is already present in large areas of Latin America.
Colombia and Ecuador, the countries where there is more presence of Mu
Just as it arose in Colombia, where it occupies 39% of the cases, Ecuador is the other country with great relevance in the Mu variant (13%). Hence the fact that the WHO has extended its surveillance on this variety of covid-19, which has the property of mutating in short periods of time.
In addition, among its characteristics that raise more alerts is the condition that the antibodies can be ineffective to its mutations as well as it is more difficult to diagnose. In any case, researchers continue studies on Mu in order to learn more about this variant and stop it in time for it to become highly dangerous.
Currently, there are up to four variants that the WHO describes as worrisome, while five are under surveillance. A list where Mu has already been added as the last stone that emerges in the fight to bend the arm of the pandemic.
