THE Delta Covid variant may mutate itself into self-extinction and has already done so in one part of the world, scientists claim.
Japan is recording an insignificant 140 cases a day despite being riddled with the Delta strain only three months ago.
Japan endured its largest Covid wave in the late summer, with cases peaking at around 23,000 a day in August.
But the wave came to an abrupt standstill and has almost completely fizzled out, with the capital Tokyo recording just 16 new cases on Friday.
A team of genetic experts in Japan have theorised the sudden slump in coronavirus is because Delta has taken care of its demise through mutating.
As a virus replicates, its genes undergo random “copying errors” which, over time, lead to changes in the viruses’ makeup.
The mutations may make it more able to spread, dodge immunity or cause severe disease.
