scabies
Let an agent explain scabies and its forms, relay transmission, diagnosis, treatment and control from dermatology and public health sources in general terms, route people with symptoms to clinicians, and distinguish scabies from other itchy rashes, from lice and from animal mange as a related condition.
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 scabies and its forms, relay transmission, diagnosis, treatment and control from dermatology and public health sources in general terms, route people with symptoms to clinicians, and distinguish scabies from other itchy rashes, from lice and from animal mange as a related condition.
A contagious skin infestation by the mite Sarcoptes scabiei, causing intense itching and a rash from burrows, spread by prolonged skin contact, occurring as classical scabies and as crusted or Norwegian scabies with heavy mite loads in immunocompromised people, and in animals as sarcoptic mange including fox mange; scabies is a neglected tropical disease affecting hundreds of millions and is treated with topical or oral medicines under medical care.
What it is for: Not applicable; a disease.
It can be explain forms and transmission; relay diagnosis and treatment; route to clinicians; distinguish related conditions.
Distinguishing features
Mite infestation
Contact transmission
Crusted form
Neglected tropical disease
What it looks like
Not a visible object; itchy rash with burrows between fingers and on wrists.
Physical character
people affected: about 200 million - WHO estimates
mite: Sarcoptes scabiei organism
incubation: 2-6 weeks - first infestation
WHO NTD listing: 2017 year
How it is recognised
Mite infestation of the skin
Classical scabies, crusted or Norwegian scabies, fox mange
Eczema and other rashes lack mites; lice are insects; mange is the animal form

What the second pass must settle
- Should crusted scabies and sarcoptic mange be separate primary entries?
- How should public health sources be linked?
- The registry entry has merged aliases naming a form and an animal disease; should they be split off?
