Possibly have you formerly had acute rhinitis? By chance did you recover from the issue? Naturally you got over it! You won't cure an acute rhinitis itself, yet your immune system typically develops immunity to a particular cold infection within a few days. That is called being cured by your personal immunity!

Parents have in the past had a great deal of the rhinitis viruses. Grownups have created immunity to the colds they have had. Therefore there are not lots of runny nose infections around for adults to acquire. That is why adults just get infected with a couple of colds each year and youngsters get a dozen runny noses each year.
