chickenpox
Let an agent explain chickenpox and its course in general terms from public health sources, describe complications and risk groups, relay vaccination and infection control guidance, and route personal cases 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 chickenpox and its course in general terms from public health sources, describe complications and risk groups, relay vaccination and infection control guidance, and route personal cases to clinicians.
A highly contagious disease caused by primary infection with the varicella-zoster virus, producing fever and an itchy rash of blisters, usually mild in children but more severe in adults, pregnant women, newborns and immunocompromised people, with complications such as bacterial skin infection, varicella pneumonia and encephalitis, and congenital varicella syndrome when infection occurs in early pregnancy; the virus then remains latent and can reactivate as shingles, and vaccination has greatly reduced cases where used.
What it is for: Not applicable; a disease.
It can be explain the disease and course; describe complications and risk groups; relay vaccination and control; route personal cases.
Distinguishing features
Blister rash in crops
High contagiousness
Latency and shingles
Vaccine preventable
What it looks like
Not a visible object; an itchy rash of small blisters in crops.
Physical character
incubation: 10-21 days
contagious period: from 1-2 days before rash until lesions crust period
vaccine effectiveness against any disease: about 80-90 percent - one dose; higher with two
How it is recognised
Primary varicella-zoster infection
Childhood chickenpox, severe adult varicella, varicella pneumonia, congenital varicella
Shingles is reactivation of the same virus; measles and hand, foot and mouth disease have different rashes
