In brief: Sometimes
Not always.
Sinusitis just means inflammation of the sinus cavities. The symptoms can be nasal congestion, pressure or headaches over the sinuses, tooth pain, nasal discharge (clear or purulent), postnasal drip, sore throat, fevers, fatigue or bad breath. It can be caused by anything that inflames the sinuses, like viruses, bacteria, allergies, smoke, fumes, etc., thus we treat the cause.

In brief: Yes
Most commonly sinusitis is caused by a bacterium called pneumococcus or one called nontypable haemophilus influenza or one called moraxalla.
These are infectious but not contagious.
