meningitis
Let an agent explain meningitis and its causes, relay symptoms, diagnosis, treatment and prevention from medical references in general terms, route anyone with suspected meningitis to emergency care first, and distinguish meningitis from encephalitis, migraine and other causes of headache and fever.
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 meningitis and its causes, relay symptoms, diagnosis, treatment and prevention from medical references in general terms, route anyone with suspected meningitis to emergency care first, and distinguish meningitis from encephalitis, migraine and other causes of headache and fever.
Inflammation of the meninges, the membranes surrounding the brain and spinal cord, caused most often by viral or bacterial infection and also by fungi, parasites such as trypanosomes, cancer as neoplastic meningitis or meningeal carcinomatosis, drugs and autoimmune disease, presenting with headache, fever, neck stiffness and altered consciousness, sometimes with brain involvement as meningoencephalitis, and in chronic forms lasting weeks; bacterial meningitis is a medical emergency requiring immediate care, and vaccines prevent several major causes.
What it is for: Not applicable; a disease.
It can be route emergencies first; explain causes and types; relay diagnosis, treatment and prevention; distinguish related conditions.
Distinguishing features
Meningeal inflammation
Emergency in bacterial cases
Many causes
Vaccine-preventable causes
What it looks like
Not a visible object; clinical signs and a rash in some bacterial cases.
Physical character
global deaths: about 250000 per year - estimates
bacterial case fatality: about 10 percent - with treatment
key vaccines: meningococcal, pneumococcal, Hib list
How it is recognised
Inflammation of the meninges
Viral, bacterial, fungal, chronic, neoplastic meningitis, meningoencephalitis, trypanosomal meningitis
Encephalitis inflames the brain itself; migraine lacks fever and stiffness
