Alphacoronavirus

Alphacoronavirus (pronounced: al-fa-koro-na-vi-rus) is a genus of viruses in the subfamily Orthocoronavirinae in the family Coronaviridae, in the order Nidovirales. Alphacoronaviruses are primarily responsible for causing diseases in mammals, including humans.

Etymology

The term "Alphacoronavirus" is derived from the Greek letter "Alpha" and the Latin "corona", meaning crown. This is in reference to the characteristic appearance of the virus particles (virions), which have a fringe of large, bulbous surface projections creating an image reminiscent of a royal crown or of the solar corona.
