And sure you will most likely get infected by a different runny nose virus, due to the fact that there remain over 300 various cold infections. Yet you will never ever get the very same runny nose infection that you had previously because you have created resistance to that cold virus.Adults have already had a great deal of the rhinitis infections. Parents have actually established resistance to the viruses they have had. So there are not lots of cold infections around for parents to become infected with. That is why adults just succumb to a few colds per year whereas children get a dozen runny noses each year.
