Three distinct strains of COVID-19 have been identified by Dr. Peter Forster, a geneticist at the University of Cambridge, and his team after they traced the origins of the pandemic by analyzing 160 genomes from human patients and finding that the strain in Wuhan, the hardest-hit city in China, mutated from an earlier version.
Dr. Peter Forster, the lead author of the study, further explained the research in an interview with China Global Television Network (CGTN) on Saturday.
This study found that the earliest known strain of the virus, termed by the scientists as "Type A", is commonly detected in the US and Australia. Type A is discovered to be the "ancestral type according to the bat outgroup coronavirus".
The "Type B," which is mostly found in East Asia, is a mutated version of Type A. European nations are currently been hit largely by "Type C," a mutation of Type B.
