The SARS-CoV-2 virus is a betacoronavirus, like MERS-CoV and SARS-CoV. All three of these viruses have their origins in bats. The sequences from U.S. patients are similar to the one that China initially posted, suggesting a likely single, recent emergence of this virus from an animal reservoir.

When looking at web results make sure to check a few things before you believe what you read. Can you tell WHO wrote the information, look both at the author's credentials and the publishing site, is it a local news reporter (see example Can it alter DNA?) or the Centers for Disease Control? Can you tell how OLD the information is; with the rapidly changing information coming out about this disease information that is more than a few months old may be out of date (the information from the Mayo Clinic is from a good source but is almost 6 months old, could you trust information from last March when this disease was just identified?)
