And sure you will probably get infected by a different cold, due to the fact that there are over 300 different cold infections. Yet you will never acquire the exact same runny nose infection that you had before because you have actually developed resistance to that cold virus.

Parents have previously had a great deal of the rhinitis viruses. Grownups have developed immunity to the colds they have actually suffered from. Therefore there are not quite as many runny nose infections remaining for adults to become infected with. That is why grownups only get a few runny noses annually and youngsters may get 10-12 colds annually.
