A member asked:

Is sinus infection contagious through kissing and can sinus infection be caused by allergies?

A doctor has provided 1 answer

Yes: Sinus infection can be passed by close personal contact or body fluids. Kissing definantly qualifies. Allergies can cause sinus inflammation that can mimic infection. Allergies can also make it easier for an infection to take hold. I hope this helps.
