COVID-19: genetic network analysis provides ‘snapshot’ of pandemic origins
Study charts the 'incipient supernova' of SARS-CoV-2 through genetic mutations as it spread from China and Asia to Australia, Europe and North America.

There are THREE separate types of coronavirus
Methods used to trace the prehistoric migration of ancient humans was adapted by researchers at the University of Cambridge to track the spread of SARS-CoV-2, which causes COVID-19.

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
