Question: What Causes Colds?

Colds are caused by any of 200+ viruses, with the majority of them being from the rhinovirus family. They are called rhinoviruses because under an electron microscope, they have horns and charge other viruses, yes like the rhino.

Actually, the name comes from the Greek word for nose, but that didn’t sound exciting enough.

These viruses are highly contagious because a person with the virus will spread it to nearly anything they touch, infecting the next person who touches it. That’s why most colds infect multiple family members or coworkers.
