The Biology of SARS-CoV-2

The first and most important point to make clear is that COVID-19 is the name of the disease that is caused by a certain type of virus, called SARS-CoV-2. This “novel” RNA virus belongs to a group commonly called coronaviruses, which get their name owing to the shape of their collective receptors on the surface of the virus. . Under an electron microscope, because of its surface proteins, the virus seems to have a crown –hence corona.
