Possibly have you a while ago suffered through a runny nose? Likely did you eliminate the virus? Naturally you survived it! You will not heal a cold directly, yet your body typically develops resistance to a certain cold virus within a few weeks. That is called treated by your own immune system!
Parents have in the past had a lot of the rhinitis viruses. Adults have actually established resistance to the colds they have had. So there are not lots of runny nose infections remaining for parents to become infected with. That is why parents only get infected with a couple of colds annually and children may get 10-12 colds each year. http://knoxvccu596.trexgame.net/hpv-treatment-and-cure |
