hepatitis
Let an agent explain hepatitis and its main causes in general terms, relay prevention, vaccination, testing and treatment information from health authorities, and route personal symptoms, results and treatment 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 explain hepatitis and its main causes in general terms, relay prevention, vaccination, testing and treatment information from health authorities, and route personal symptoms, results and treatment questions to clinicians.
Inflammation of the liver, most often caused by viral infection with hepatitis A, B, C, D or E viruses, and also by alcohol, drugs and toxins, autoimmune disease and metabolic conditions; it ranges from acute self-limiting illness to chronic infection leading to cirrhosis and liver cancer, and is a major global public health concern with vaccines available for some forms.
What it is for: Not applicable; a disease.
It can be explain causes and types in general terms; relay prevention and vaccination guidance; relay testing and treatment information from authorities; route personal questions to clinicians.
Distinguishing features
Liver inflammation with many causes
Viral forms differ in transmission and chronicity
Vaccines exist for hepatitis A and B
Chronic forms are treatable and hepatitis C is curable with modern drugs
What it looks like
Not visible as an object; may present with jaundice, fatigue and abdominal symptoms, or no symptoms.
Physical character
chronic hepatitis B and C: hundreds of millions people worldwide - WHO estimates; figures change
incubation: weeks to months time - by virus
How it is recognised
Liver inflammation confirmed by blood tests and clinical assessment
Viral types A to E have different transmission and courses
Cirrhosis and liver cancer are consequences with their own entries

Identifiers
ICD-10 B15-B19 and K70-K77 viral and other hepatitis codes

National immunisation schedules
Notifiable disease reporting rules
Blood and organ donation screening rules
Failure modes and hazards
Undiagnosed chronic infection progressing to cirrhosis and cancer
Transmission through blood, sex, birth and contaminated food or water
Stigma delaying testing

- How should national guidelines be linked?
- The registry entry has merged aliases including an animal disease; should they be split off?
