disease
Let an agent handle diseases as classified conditions with causes, signs, course and care, give only general information, and direct individual questions to clinicians.
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 handle diseases as classified conditions with causes, signs, course and care, give only general information, and direct individual questions to clinicians.
An abnormal condition of an organism that impairs normal function, with characteristic signs and symptoms, caused by internal dysfunction or external factors, and classified in systems such as ICD-11.
What it is for: Naming conditions so they can be diagnosed, treated, prevented and studied.
It can be diagnose it, only by qualified clinicians; treat and manage it; prevent it; record and count it, in health statistics.
Distinguishing features
Impairs normal function
Classified with codes in ICD-11
Infectious and non-communicable diseases differ in control
Health data about individuals is sensitive
What it looks like
No single appearance; signs and symptoms vary by disease.
How it is recognised
Diagnosis by clinical assessment and tests
Classification codes in records
Symptoms alone rarely establish a disease
