The corona virus (or a specific kind thereof) is a hot topic, and one should of course be able to discuss it in Latin. But what should we call the thing in Latin? Both corona and virus are Latin words, but it's not clear that they could be used together just like that.
A corona is a crown, garland, or other similar headgear. I've been told that microscopically the virus has a shape remotely resembling a crown. A virus is poison, virus, or some slimy or otherwise foul substance. The first impression from this word is not that it refers to a virus as we understand the concept in today's biology.
