And of course you will possibly succumb to one more cold virus, since there are over 300 different runny nose infections. Yet you will unlikely get the same cold infection that you had previously since you have actually created immunity to that cold virus.
Adults have already had a lot of the cold viruses. Adults have created resistance to the colds they have actually had. So there are not numerous runny nose infections remaining for parents to catch. That is why parents only get infected with a couple of colds each year whereas children get a dozen runny noses annually. https://atavi.com/share/w7gveiz1cigdt |
