The World Health Organisation closely monitors another, Mu or B.1.621, that might emerge as a variant of concern in the recent future as it showed signs of possible vaccine resistance.
Where had the new Mu variant originated
The variant of interest was first identified in Columbia in January 2021. Since then, reports have been sporadic, more significant outbreaks in and around Europe and South America, the UN health agency’s weekly bulletin said.
Over 4,500 samples were genome sequenced on August 29 and analyzed samples were designated as Mu. Most cases were detected from the US, followed by Columbia, Mexico, and then Span. Issues of the new variant of interest were also reported in the UK, Europe, and.
Why is it on WHO’s watchlist?
The variant was added to WHO’s watchlist on August 30 afterwith the same variant were found in 39 countries. On genome sequencing, it was found that the variant went through a constellation of mutations that indicate that can make it evade immune response from vaccination.
The prevalence of the sequenced cases is the highest in Columbia at 39% and then in Ecuador at 13% e of the Muprevalence is below 0.1 percent.
The Mu variant of the B.1.621 lineage has been under WHO’s scanner since March for undergoing several mutations that make it vaccine resistant but said that further research is required to confirm the same. According to the preliminary data, the variant escapes immune defenses similar to beta variants first found in. According to WHO, more studies were needed to understand its phenotypic and clinical characteristics.
Mu variant is resistant to a vaccine, as Beta: PHE report.
According to risk management of the new variant report released byEngland, the variant can resist immunity from vaccination at least as much as the Beta variant. Moreover, WHO’s preliminary can also evade the natural immunity created by a body due to earlier infection and immunity formed by vaccination.
Is the Mu variant more transmissible?
A report by the Guardian says there is so far no evidence that supports that it is out-competing the, and it appears unlikely that it is more transmissible. But immune escape can dictate how it spreads in a population in the future. The Mu variant’s threat now depends on whether cases grow substantially in the and months.
Meanwhile, another potential variant of interest, C.1.2, is closely monitored in. The cases were first detected in May this and found in England, New Zealand, Switzerland, Portugal, China, Mauritius, and the Democratic Republic of the Congo.
However, C.1.2 has not beenby WHO. So far, WHO has classified four variants of a problem – Alpha, Beta, Delta, and Gamma – along with five variants of interest, including Mu.
