And of course you will most likely get infected by one more runny nose virus, since there exist more than 300 various runny nose viruses. Yet you will never ever get the very same runny nose infection that you had before due to the fact that you have actually created immunity to that cold virus.

Grownups have currently had a great deal of the runny nose viruses. Grownups have acquired resistance to the ones they have had. So there are not as many cold infections around for adults to catch. That is why adults only acquire a few colds each year and youngsters may get 10-12 colds annually.
