And sure you will eventually get a different cold virus, due to the fact that there remain more than 300 different cold infections. But you will certainly never ever acquire the very same runny nose infection that you had previously since you have established immunity to that particular cold virus.Parents have currently had a great deal of the runny nose viruses. Adults have actually established resistance to the colds they have had. So there are not so many cold infections around for grownups to catch. That is why parents just succumb to a few colds per year and kids acquire 10-12 colds each year.
