A new, potentially more infectious variant of the novel coronavirus that causes COVID-19 has been found in Britain in cases linked to South Africa, British Health Secretary Matt Hancock said on Wednesday.<br /><br />South Africa's health department said last week that a new genetic mutation of the virus had been discovered and might be responsible for a recent surge in infections there.<br /><br />"Thanks to the impressive genomic capability of the South Africans, we've detected two cases of another new variant of coronavirus here in the UK," Hancock told a media briefing.<br /><br />"Both are contacts of cases who have travelled from South Africa over the past few weeks."<br /><br />Britain is already trying to curb the spread of a mutated strain of the virus which is up to 70% more transmissible, and further studies aerie being carried out on the new variant.
