Remember SARS? Or the last time you had a nasty cold? Lay your troubles at this bad-boy's door.
In fact, SARS-CoV - the Corona variant that causes SARS - has the rather unique quality of causing both upper & lower respiratory infections, and gastroenteritis.
Note as well that the Coronavirus, represented here in 3D via graphical imaging, gains it's name from a Greek word meaning "crown" - kinda makes sense right?
