In brief: Frequently

Most sinus infections start with nasal membrane swelling from allergy or a virus, then go onto a bacterial sinusitis within 7-10 days.

In brief: Sometimes

Acute sinusitis can be caused by bacteria but more often by viruses.
In fact, this is why antibiotics are not usually recommended, unless symptoms do not improve or worsen after a week or more. If symptoms improve within a week, it is not likely to be bacterial. Of course, treat your symptoms by rinsing nose with saline, taking a pain reliever and decongestant spray as appropriate.
