Are Sinus Infections Contagious?

The short answer from a rhinologist
"Are Sinus Infections Contagious? (Short answer)"

Q: Are sinus infections contagious?

A: Sometimes they are, and sometimes they aren’t. Sinus infections that are  caused by bacteria, allergies, polyps or immunodeficiencies (conditions that impact how well your immune system works) are not contagious. On the other hand, infections caused by viruses are contagious. They can be spread via droplets by hand to hand contact or in the air. When a virus is passed to another individual, they may develop a cold, which may or may not progress to become a sinus infection. Rhinologist Troy Woodard, MD
