Probably have you hitherto suffered through acute rhinitis? By chance did you eliminate the infection? Naturally you survived it! You cannot cure a common cold itself, nevertheless your system generally establishes resistance to a specific cold infection within a few days. We call that being cured by your personal immune system!Adults have actually already had a lot of the rhinitis viruses. Adults have acquired resistance to the viruses they have suffered from. So there are not as many runny nose viruses around for grownups to acquire. That is why adults only get a few runny noses per year whereas children acquire 10-12 colds each year.
