What Is a Sinus Infection? A sinus infection occurs when the cavities surrounding the nasal passages become inflamed. If your sinus infection is caused by a virus, then you will be contagious and might need to take certain precautions to ensure you do not get others sick. However, if your sinus infection is bacterial, you are not contagious to those around you.

Are There Different Types of Sinus Infections?
There are two main types of sinus infections—acute sinusitis and chronic sinusitis. While acute sinus infections usually last less than a month, a chronic sinus infection can last longer.

A doctor can help evaluate what type of sinus infection you’re experiencing.Reasons for Sinus Infections
