Trichuriasis is an intestinal infections caused by whipworms. Whipworms are small worms shaped like a whip, of the species Trichuris (hence Trichuriasis). In a bad infection there are 250 or more worms passed in their faeces each time a person goes to toilet.
Trichuriasis can cause persistent diarrhoea. Prolonged infection can delay the development of mental and motor skills in infants and temporarily impair the ability of school-age children to understand and learn. There is an effective drug treatment. The spread of infection and recurrence of infection can be reduced by better hygiene, especially hand washing, and good sanitation.
Trichuriasis caused 0.005% of all deaths worldwide in 2002, with an average of 0.5 deaths per million people.
