So I think you have an implied question as to whether there is some more specific meaning, the answer to that is no.
> The common cold, also known simply as a cold, is a viral infectious disease of the upper respiratory tract that primarily affects the respiratory mucosa of the nose, throat, sinuses, and larynx.

> Well over 200 virus strains are implicated in causing the common cold, with rhinoviruses being the most common.[13]
Also, my quick read of that paper was that it was mostly concerned with immunocompromised individuals, and with secondary pneumonia infections. Secondary pneumonia is certainly a problem for old people, or otherwise vulnerable people with colds. Antibiotics can be pretty helpful but they have limitations.
