Possibly have you ever been down with a runny nose? By any chance did you do away with the virus? Obviously you survived it! You will not heal a common cold directly, however your immune system typically establishes resistance to a particular cold virus within a few weeks. We call that treated by your personal immune response!

Parents have actually in the past had a lot of the rhinitis viruses. Grownups have actually developed immunity to the colds they have suffered from. Therefore there are not as many runny nose infections around for grownups to become infected with. That is why adults just get a couple of colds per year and youngsters usually get a dozen colds per year.
