In the opinion of the eight virologists these viruses are members of a previously unrecognized group which they suggest should be called the coronaviruses, to recall the characteristic appearance by which these viruses are identified in the electron microscope. [56] Coronavirus was accepted as a genus name by ICNV in its first report in 1971. [57]
Transmission and life-cycle of SARS-CoV-2 causing COVID-19. Coronaviruses vary significantly in risk factor. Some can kill more than 30% of those infected, such as MERS-CoV, and some are relatively harmless, such as the common cold. [49] Coronaviruses can cause colds with major symptoms, such as fever, and a sore throat from swollen adenoids. [91]

Around 10% to 30% of non-hospitalised people with COVID-19 go on to develop long COVID. For those that do need hospitalisation, the incidence of long-term effects is over 50%. [14] Long COVID is an often severe multisystem disease with a large set of symptoms. There are likely various, possibly coinciding, causes. [14]
