According to the Daily Mail, analysis of the genetic history of SARS-CoV-2 or the novel coronavirus shows that Type A, which is the strain that came from bats and jumped to humans from pangolins, was not common in China--the origin of the outbreak.
Two-thirds of the samples acquired from the U.S. showed that they have a Type A novel coronavirus and that the infected patients did not come from New York, which is considered an epicenter of the COVID-19 infection in the U.S.
Instead, most of the patients came from the
West Coast.
On the other hand, Type C coronavirus strain is also common in some places in Europe as well as in Asia, specifically in Singapore. This strain is the "daughter" of Type B and is just one mutation different from it.
Так что по алфавиту, А В С.
В Америке родина вируса от летучих мышей, в Америке.
