diphtheria
Let an agent explain diphtheria in general terms, relay symptoms, transmission, vaccination and treatment principles from public health sources, relay outbreak and coverage data with sources, and route personal symptoms and vaccination questions to clinicians and health authorities.
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 diphtheria in general terms, relay symptoms, transmission, vaccination and treatment principles from public health sources, relay outbreak and coverage data with sources, and route personal symptoms and vaccination questions to clinicians and health authorities.
A serious bacterial infection caused by toxin-producing strains of Corynebacterium diphtheriae and related species, affecting mainly the throat and nose, where a grey membrane forms, and sometimes the skin, with toxin damaging the heart and nerves; diphtheria spreads by respiratory droplets, was a major cause of child death before vaccination, is now rare where immunisation coverage is high, and is a notifiable disease treated with antitoxin and antibiotics.
What it is for: Not applicable; a disease.
It can be explain the disease and its forms; relay vaccination and prevention information; relay outbreak and coverage data; route personal questions to clinicians.
Distinguishing features
Toxin-mediated
Pseudomembrane
Vaccine-preventable
Notifiable
What it looks like
Not a visible object; signs include sore throat, fever, swollen neck and a grey membrane in the throat.
Physical character
case fatality: about 5-10 percent - higher in young children and untreated cases
vaccine introduced: 1920s decade - toxoid
How it is recognised
Toxin-mediated infection with throat membrane
Respiratory and cutaneous forms
Streptococcal sore throat and other membranous infections are distinguished by testing

What the second pass must settle

- How should WHO data be linked?
- The registry entry has merged aliases naming complications and rare forms; should they be split off?
