Causes
The whipworm Trichuris vulpis. It is transmitted by ingesting eggs from the soil. The eggs survive in the environment for years.
Diagnosis
Faecal analysis. The eggs are shed intermittently, so several samples may need to be tested.
Treatment
An effective wormer against whipworms, often in repeated courses. Environmental hygiene to reduce reinfection.
Prevention
Regular deworming, picking up faeces daily, and avoiding heavily contaminated areas.
