What we call a common cold is really just any viral infection of the upper respiratory system, so the nose and throat areas not down deep in the lungs. If you wanted a fancier name you could call it nasopharyngitis.
It can be caused by a wide range of different viruses. Rhinovirus is the most common, but others include human coronaviruses (not SARS-CoV-2 but older ones), influenza and RSV.
