In brief: Viral and bacterial
Sinusitis is an inflammation of the paranasal sinuses in the face and frontal bones.
It always starts with a viral rhinitis (cold) and in about 2% of cases becomes secondarily infected with bacteria. Thus viruses and bacteria and rarely fungi can spread from the nose and enter through very small openings in the lateral wall of the nose into the sinuses.
