More than 50 Britons have been infected with the ‘Mu’ COVID variant which experts fear blunts the effect of vaccines and is already sweeping across the US. Public Health England said it had spotted 53 cases of the mutant strain which first emerged in Colombia.
Scientists believe that while Mu is more transmissible than the original virus, it does not appear to be infectious enough to outcompete the Delta variant.
Professor Lawrence Young, a virologist at Warwick Medical School, said he believed Delta represented ‘peak infectiousness’ for Covid and would be ‘very, very surprised’ if Mu or any other strain was even more transmissible.
No one in Britain has died from the Mu strain, but give people have been admitted to hospital with it.
