Fail link ahead but the quoted research comes from Cambridge University. Not sure what the implications for either organic herd immunity or vaccine are.
There are THREE distinct strains of the novel coronavirus in the world and while China's epidemic was driven by an early mutation that quickly spread in the UK, the US is suffering from an original variation
Type A is closest to the one found in bats and pangolins and has two sub-clusters
One sub-cluster linked to Wuhan and the other is common in US and Australia
Type B is derived from type A and has become the most prevalent in Wuhan
Type C is the 'daughter' of type B and was spread to Europe via Singapore
Three types of the deadly coronavirus are spreading around the world - and the US is being rocked by the original strain from China.
Cambridge University researchers mapped the genetic history of the infection from December to March and found three distinct, but closely related, variants.
