Abstract

To determine the relationship between human lymphatic filariasis, caused by Wuchereria bancrofti, and falciparum malaria, which are co-endemic throughout West Africa.
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.
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.
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.
Determiner la relation entre la filariose lymphatique causee par Wuchereria bancrofti et la malaria falciparum, toutes deux endemiques en Afrique de l'ouest.
Nous avons utilise les systemes d'information geographique et des statistiques spatiales pour examiner la prevalence de la filariose lymphatique en relation avec la prevalence de la malaria, la distribution des especes de moustiques, la vegetation et le climat.
Une association spatiale negative existe entre W. bancrofti et la prevalence de la malaria falciparum. La competition inter-espece des parasites, la saisonnalite, les differences dans la distribution et la competence des vecteurs Anopheles, les pratiques agriculturales et la resistance aux insecticides peuvent etre des facteurs responsables des distributions spatiales actuelles et probablement futures.
Une investigation plus poussee de ces facteurs s'averera cruciale avec l'introduction de programmes de controle a grande echelle de la filariose lymphatique et de la malaria en Afrique de l'ouest, qui peuvent influencer l'epidemiologie de ces deux maladies.
Determinar la relacion entre la filariasis linfatica humana, causada por Wuchereria bancrofti, y malaria por Plasmodium falciparum malaria, las cuales son co-endemicas en todo Africa del oeste.
Utilizamos sistemas de informacion geografica (SIG) y estadistica espacial para examinar la prevalencia de filariasis linfatica en relacion a la prevalencia de malaria, la distribucion espacial de los mosquitos, la vegetacion y el clima.
Existe una asociacion espacial negativa entre W. bancrofti y malaria por P.falciparum. Los factores que podrian estar influenciando las distribuciones espaciales actuales (y potencialmente las futuras) son la competencia entre especies de parasitos, la estacionalidad, diferencias en la distribucion y competencia de los vectores Anopheles, practicas agricolas y resistencia a insecticidas.
Investigar mas a fondo estos factores sera crucial a medida que se implementen en Africa del Oeste, programas de control a gran escala para la malaria y la filariasis linfatica, que puedan influenciar la epidemiologia de ambas enfermedades.
