All human coronavirus diseases, including COVID-19, are colds. Always have been. This one from 1890 might have been caused by OC43:
There are colds caused by influenza viruses, but because "the common cold is defined on the basis of its clinical presentation, a mild influenza infection can accurately be diagnosed as a cold, meaning that the two infections are not completely distinct disease entities."[0] Once someone with a cold tests positive for the flu, though, we would generally correct the description to a mild case of the flu and no longer say they have a cold.

Is it possible that all coronaviruses, including the ones that cause a common cold, have a similar morbidity profile to COVID? Very minor infection in the young or those with previous exposure, extremely deadly in the old and naive. Except we all catch a bunch of colds in childhood, so nobody has to worry about a cold wiping out nursing homes.
We clearly don’t have the faintest understanding of the long-term dynamics of something like SARS, when all the conventional model parameters go to such extremes. And when the disease is evolving. And when people retreat inside and stop getting sun. And so on.
What exactly have you been saying?
What constitutes a "cold"? Is there some kind of definition for it?
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.
> 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]
So I think you have an implied question as to whether there is some more specific meaning, the answer to that is no.
