Overview

There are 3 main types of tonsillitis: acute, subacute and chronic.

The three classifications of tonsillitis are:

Disease	Definition
Acute	Acute tonsillitis can either be bacterial or viral (75%) in origin
Subacute	Subacute tonsillitis (which can last between 3 weeks and 3 months) is caused by the bacterium Actinomyces
Chronic	Chronic tonsillitis, which can last for long periods if not treated, is almost always bacterial.
