At least 32 cases of the Mu variant have been detected in the UK – largely in London – where it is believed to have been brought in by travellers.
While the variant makes up less than 0.1% of Covid infections globally, it may be gaining ground in Colombia and Ecuador where it accounts for 39% and 13% of Covid cases respectively, The Guardian reported.
Health officials are now trying to determine if the Mu variant is more transmissible, and more damaging, then the Delta variant that is the current dominant strain.
The WHO bulletin states: “The epidemiology of the Mu variant in South America, particularly with the co-circulation of the Delta variant, will be monitored for changes.”
The Mu variant was added to Public Health England’s list of variants under investigation in July.
The designation, which refers to Mu as VUI-21JUL-01, means the variant will be monitored to see how it behaves, The Guardian reported, adding that so far it had not raised alarm as much as Alpha and Delta.
