No doubt you will possibly acquire an additional runny nose virus, because there remain more than 300 various cold viruses. But you will certainly never get the exact same cold infection that you had previously because you have actually developed immunity to that particular cold virus.Grownups have actually already had a lot of the runny nose viruses. Grownups have developed resistance to the colds they have actually had. Therefore there are not as many cold viruses remaining for adults to become infected with. That is why adults only get a couple of colds annually whereas kids may get a dozen colds each year.
