And sure you will possibly get infected by another cold virus, since there remain 300 various cold infections. But you will certainly never get the very same runny nose virus that you had in the past due to the fact that you have established immunity to that virus.Parents have actually in the past had a lot of the rhinitis viruses. Adults have acquired resistance to the colds they have had. Therefore there are not as many runny nose viruses around for adults to catch. That is why parents just acquire a couple of runny noses each year and kids usually get 10-12 colds each year.
