What constitutes a "cold"? Is there some kind of definition for it?

It's a lay term for the various respiratory viruses that are pretty much constantly in circulation, especially when the infection is symptomatic.

So I think you have an implied question as to whether there is some more specific meaning, the answer to that is no.

https://en.wikipedia.org/wiki/Common_cold

> 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.

further down,

> Well over 200 virus strains are implicated in causing the common cold, with rhinoviruses being the most common.[13]

Exactly! Colds are poorly understood, and can be very dangerous.

That link appears to be about the flu, not the common cold. They're different, but something I've learned over the past year is that most people think of the flu as another name for the common cold.
Here in Britain at least, having 'the flu' is basically having a particularly miserable cold - rather than a bout of influenza which fills the lungs with fluids and decimates armies.
“Objectives: To define the epidemiology and outcomes of non-influenza respiratory viral infections in hospitalized adults.”
I'm not sure this will really add anything to the discussion, but I think the common usage of the term "cold" is for an endemic, mostly-harmless disease, not just any viral respiratory illness.

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.

...I don’t see the word “cold” in that paper.
