Abstract

Simple pit latrines often represent the cheapest form of sanitation for poor communities. However, simple latrines lack a concrete slab and are therefore classified as an unimproved form of sanitation. This study collected soil samples in simple pit latrines and analysed them for the presence of helminth eggs; 71% of all collected samples were positive for eggs. The absence of a roof from the latrine was the only factor associated with lower egg concentrations. The findings support the classification of simple pit latrines as an unimproved form of sanitation.
