The type A of virus is thought to have gone from bat to human, through an animal called pangolin. The results showed that Type A virus was common in the United States and Australia.
But the common virus in China, the place where it is thought to be the infection, was not the type A, but type B, which has been on the roll since Christmas.
Another variation of the virus is that of type C, which has spread widely to Europe and Singapore.
Scientists believe that the virus officially known as Sars Cov-2 is undergoing constant mutations, to resist the immune system of various populations and to continue spreading.
The data that was analyzed by scientists shows that the original virus has circulated in China since September 2019. This means that the virus had mutated before first cases were recorded in China with Covid-19. Wwan reported cases of a mysterious virus on December 31, 2019.
