And of course you will eventually succumb to a different cold virus, since there are more than several hundred various cold infections. But you will never get the exact same runny nose infection that you had previously due to the fact that you have established immunity to that particular virus.Grownups have actually previously had a great deal of the rhinitis infections. Adults have developed immunity to the ones they have actually had. So there are not quite as many runny nose viruses remaining for grownups to acquire. That is why grownups just acquire a few runny noses annually and kids succumb to a dozen colds each year.
