SARS is actually SARS-CoV, MERS is actually MERS-CoV, this virus is CoVID-19, and all three are different strains of the coronavirus. COVID-19 is actually a strain that came directly from the SARS virus
And also why research for a drug or vaccine that will control it was well underway before this strain of the coronavirus emerged.
Hindsight, a wonderful thing.
God bless RNA viruses, aren’t they a wonder of creation.
