cellulitis
Let an agent explain cellulitis in general terms, relay signs, risk factors and treatment principles from clinical guidelines, distinguish it from look-alike conditions and from the registry aliases that name unrelated diseases, and route personal symptoms to clinicians, with urgent routing for orbital and rapidly spreading cases.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain cellulitis in general terms, relay signs, risk factors and treatment principles from clinical guidelines, distinguish it from look-alike conditions and from the registry aliases that name unrelated diseases, and route personal symptoms to clinicians, with urgent routing for orbital and rapidly spreading cases.
A bacterial infection of the deeper layers of the skin and the tissue beneath it, usually caused by streptococci or Staphylococcus aureus entering through a break in the skin, producing a spreading area of redness, warmth, swelling and pain, often with fever; cellulitis most often affects the lower leg, can become serious if it spreads or involves the eye socket, as in orbital cellulitis, and is treated with antibiotics.
What it is for: Not applicable; a disease.
It can be explain the condition and its signs; relay treatment principles and prevention; distinguish from look-alike conditions; route personal symptoms to clinicians.
Distinguishing features
Deep skin infection
Spreading redness and warmth
Entry through skin breaks
Antibiotic treatment
What it looks like
A spreading red, warm, swollen and tender area of skin, often on the leg, sometimes with blisters.
Physical character
common site: lower leg site - most cases
main pathogens: streptococci and Staphylococcus aureus organisms
How it is recognised
Spreading skin and subcutaneous infection
Usually one limb, with fever possible
Venous eczema and deep vein thrombosis look similar; chronic granulomatous disease and paracoccidioidomycosis are different diseases listed as aliases
