Soil-transmitted helminth infections

We are evaluating a new treatment for this common infection that affects the world’s poorest communities

OVERVIEW

What is a soil-transmitted helminth infection?

Soil-transmitted helminth infections caused by roundworm (Ascaris lumbricoides), whipworm (Trichuris trichiura) and hookworm nematodes (Ancylostoma duodenale and Necator americanus), are among the most common of all infections with an estimated 1.5 billion people infected worldwide. Malnutrition can occur in those infected, and children may also experience impairments to mental and physical growth. These parasitic worms affect the world’s poorest communities and are transmitted through contaminated soil where sanitation is inadequate.

THE STATS

Why are we targeting this disease?

1.5B

people estimated to be infected worldwide in 2016

568M+

school-age children live in areas where these parasites are intensely transmitted

2030

By 2030 the WHO is aiming for the elimination of STH morbidity in pre-school and school age children

WHAT we're DOING

Moxidectin

Current treatments recommended by the WHO are albendazole and mebendazole, which work by stopping the parasitic worms from absorbing sugar.We are evaluating moxidectin as a treatment for soil-transmitted helminths. MDGH is collaborating in Phase 2/3 studies in Tanzania, conducted by the Swiss Tropical and Public Health Institute, Switzerland. A study to evaluate moxidectin co-administered with albendazole in adolescents infected with soil-transmitted helminths will soon commence on Pemba Island, Tanzania.
