And of course you will most likely acquire another cold virus, since there remain more than several hundred different cold viruses. Yet you will certainly never ever get the exact same runny nose virus that you had in the past because you have actually established resistance to that virus.Parents have actually in the past had a lot of the runny nose viruses. Grownups have developed immunity to the viruses they have suffered from. So there are not so many cold viruses existing for adults to catch. That is why parents only succumb to a couple of colds each year whereas youngsters usually get 10-12 colds each year.
