ascariasis
Let an agent explain ascariasis in general terms, relay transmission, symptoms, treatment and control from WHO and tropical medicine sources, route severe abdominal pain or vomiting worms to urgent care, describe and flag the veterinary aliases, and distinguish ascariasis from other soil-transmitted helminthiases, toxocariasis and veterinary ascarid infections, without diagnosing individuals.
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 ascariasis in general terms, relay transmission, symptoms, treatment and control from WHO and tropical medicine sources, route severe abdominal pain or vomiting worms to urgent care, describe and flag the veterinary aliases, and distinguish ascariasis from other soil-transmitted helminthiases, toxocariasis and veterinary ascarid infections, without diagnosing individuals.
A soil-transmitted helminth infection of humans caused by the roundworm Ascaris lumbricoides, spread by swallowing eggs from soil contaminated with human faeces, one of the most common parasitic infections worldwide, mostly mild but causing malnutrition, impaired growth and sometimes intestinal or bile duct obstruction in children; it is prevented through sanitation and hygiene and controlled by periodic deworming with albendazole or mebendazole under WHO programmes. The registry aliases animal ascaridoses, avian ascariasis and heterakidosis name veterinary infections by related worms of animals and poultry and appear misfiled under this human disease.
What it is for: Not applicable; an infectious disease.
It can be explain transmission and symptoms; relay treatment and control; flag veterinary aliases; route severe symptoms to care.
Distinguishing features
Large roundworm
Faecal-oral via soil
Affects children most
Cheap treatment
What it looks like
Often no signs; large pale roundworms may be passed in stool or vomit.
Physical character
adult worm length: up to about 35 cm - female
WHO control strategy: preventive chemotherapy in endemic areas note
infected people: hundreds of millions note - WHO estimates vary
How it is recognised
Human roundworm infection by Ascaris lumbricoides
Animal ascaridoses, avian ascariasis, heterakidosis
Hookworm and whipworm are other soil-transmitted helminths; toxocariasis comes from dog and cat worms; poultry ascarids infect birds

- How should WHO data be linked and kept current?
- Should hepatobiliary ascariasis be a separate entry?
