Class I — there are no signs of systemic toxicity or uncontrolled comorbidities.

Class II — the person is either systemically unwell or systemically well but with a comorbidity (for example peripheral arterial disease, chronic venous insufficiency, or morbid obesity) which may complicate or delay resolution of infection.
Class III — the person has significant systemic upset (such as acute confusion, tachycardia, hypotension), or unstable comorbidities that may interfere with a response to treatment, or a limb-threatening infection due to vascular compromise.
Class IV — the person has sepsis or a severe life-threatening infection, such as necrotizing fasciitis.
