What are risk factors for acute sinusitis?

Some people are more likely than others to get acute sinusitis. These include:

• People who have allergies.
• People who have structural problems with their noses (like a deviated septum) or polyps, which are growths that can hang inside noses or sinus cavities.
• People who spend a great deal of time in places where infections happen, like preschools or day cares.
