Yes, a person can have more than one viral infection at the same time. True influenza is so miserable that how would you even know if you also had a common cold?
Diagnosed early and by laboratory confirmation (there is a rapid flu test), the course of influenza can be shortened by using a drug called Tamiflu. Colds, of course, have no specific treatment. They will last about a week.
