Abstract:
In order to estimate the potential benefits of interventions
against multiple geohelminth species in endemic areas, an improved understanding of the population biology of multiple infections
is required. This paper presents a detailed analysis of the associations among Ascaris lumbricoides , Trichuris trichiura and hookworm infections in 1539 schoolchildren
on Pemba Island, Tanzania, where 58% of the sampled children carried infections of all 3 parasites at the time of the
study. Infection intensities of different species were positively correlated, and individuals with single-species infections
had generally lower species-specific egg counts than individuals with multiple-species infections. There was no age- or
sex-related clustering of infections. A weak clustering of intense infections among individuals with multiple-species
infections wa s observed, which became more pronounced as the
threshold defining an intense infection increased for each species. The results suggest that individuals with multiple species
infections are likely to be at highest risk of geohelminth-related morbidity, not only because of the number of infections they harbour,
but also because they generally carry heavier infections of each species.
