- Viral infections that lead to sinusitis may be contagious; bacterial sinusitis is generally not. It’s important to remember that most viral upper respiratory infections (common colds) cause nasal congestion, which may involve the sinuses. If the viral sinus infection lasts well past the normal duration of a cold, viral sinusitis may be diagnosed.

Bacteria that are normally present in the nose and throat take advantage of the viral infection to invade the inflamed sinus passages.
