Possibly have you a while ago been down with acute rhinitis? Maybe did you do away with it? Certainly you recovered! You cannot cure a common cold directly, yet your immune system generally establishes resistance to any cold virus within a few weeks. We call that treated by your very own immune system!

Grownups have already had a great deal of the cold viruses. Grownups have acquired immunity to the ones they have suffered from. So there are not lots of cold infections existing for grownups to acquire. That is why parents just get a couple of runny noses each year whereas youngsters succumb to a dozen runny noses annually.
