"...A waterborne virus can gain entry either through direct contact with contaminated water or airborne via earosols. These are not mutually exclusive."

A good point.

[Nebullis]

What is important is not just how contact is made with the virus, something that can vary greatly even for a single species, but what kind of contact constitutes effective transmission. We won't know that about SARS until we study it more.
