And sure you will possibly get one more cold, because there remain over 300 various cold infections. However you will certainly never ever get the 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 rhinitis infections. Adults have actually developed immunity to the viruses they have suffered from. So there are not lots of runny nose infections around for grownups to catch. That is why adults just get a couple of colds annually and kids get 10-12 runny noses each year.
