This question comes about from another virology question concerning the common cold (Would being infected with every kind of cold virus strain at once be a good immunization or dangerous?).
The original edit stated that there are over 200 different viruses which cause the common cold, and after reading the linked Wikipedia article, it said just under the intro panel (the bit with a representation of a virus) what I believed to confirm my initial thought, that it is virus strains not different viruses.
Well over 200 virus strains are implicated in causing the common cold, with rhinoviruses being the most common.
So I commented the fact and after editing to suit, the author responded with (emphasis mine)
@Chris Rogers How do you explain this from wiki?The common cold is a viral infection of the upper respiratory tract. The most commonly implicated virus is a rhinovirus (30–80%), a type of picornavirus with 99 known serotypes. Other commonly implicated viruses include human coronavirus (≈ 15%), influenza viruses (10–15%), adenoviruses (5%), human respiratory syncytial virus, enteroviruses other than rhinoviruses, human parainfluenza viruses, and metapneumovirus. Frequently more than one virus is present. In total over 200 viral types are associated with colds.
I have not been able to find anything online the difference between the two (if there are any). Are the rhinoviruses, enteroviruses, metapneumoviruses etc. involved different strains of the same virus or are they different viruses all together?
