On April 9, a research team from Cambridge University and Germany published a study that has reconstructed the early “evolutionary paths” of COVID-19. The team has identified three different strains of COVID-19. Forster and his team tracked the origin of the epidemic by analyzing 160 genomes from patients and found that the virus strain in Wuhan mutated from an earlier version.

Peter Forster; No evidence that COVID-19 originated from Wuhan

Although it would be a misinterpretation of the research to suggest that the new coronavirus originated outside of China. Then the study suggests; that the new coronavirus type A is the root cause of the virus outbreak and that type A is found in the US and Australia. The virus found in Wuhan belongs to the type B derived from the type A mutation.
