And sure you will possibly acquire one more runny nose virus, because there are several hundred various cold infections. Yet you will unlikely acquire the exact same cold infection that you had before because you have actually developed resistance to that particular virus.Parents have actually previously had a great deal of the cold infections. Adults have actually acquired resistance to the colds they have actually suffered from. Therefore there are not so many runny nose infections remaining for adults to catch. That is why adults only acquire a couple of runny noses per year whereas children usually get 10-12 runny noses each year.
