No doubt you will eventually acquire another cold, due to the fact that there remain over 300 different runny nose infections. But you will unlikely get the very same runny nose infection that you had before since you have created immunity to that particular cold virus.Parents have actually in the past had a lot of the cold viruses. Adults have acquired resistance to the viruses they have had. Therefore there are not lots of runny nose viruses existing for adults to become infected with. That is why grownups only get a couple of runny noses annually whereas children usually get a dozen runny noses annually.
