Abstract

Objective To determine the relationship between human lymphatic filariasis, caused by Wuchereria bancrofti, and falciparum malaria, which are co-endemic throughout West Africa.

Methods We used geographical information systems and spatial statistics to examine the prevalence of lymphatic filariasis in relation to malaria prevalence, mosquito species distributions, vegetation and climate.

Results A negative spatial association between W. bancrofti and falciparum malaria prevalence exists. Interspecies competition between parasites, seasonality, differences in the distribution and vector competence of Anopheles vectors, agricultural practices and insecticide resistance may be factors driving current (and potentially future) spatial distributions.

Conclusion Further investigating these factors will become crucial as large-scale lymphatic filariasis and malaria control programmes are implemented in West Africa that may influence the epidemiology of both diseases.
