In 2000 Cameroon was selected for inclusion in the eradication program. As a prerequisite for the program, epidemiological mapping was undertaken to determine the prevalence of Wuchereria bancrofti in 7 villages located in the mangrove area of the Wouri estuary littoral province of Cameroon. Informed consent was obtained from each participant or from parents of minors. Night blood specimens were collected for thick and thin blood films, stained using the Giemsa solution, and microscopically examined to identify microfilariae of W. bancrofti. The study population included 924 subjects (336 males and 558 females). Their age ranged from 1 to 79 years (mean, 26.9 years). W. bancrofti was identified in 4 of the 7 villages with prevalence rates ranging from 0.7% to 3.25% (mean, 0.97%). All positive subjects were over 30 years old. Despite night blood specimen collection, other blood microfilariae were detected including Loa loa in 54 cases (prevalence, 5.84%) and Dipetalonema perstans in 10 (prevalence, 1.1%). Only a small number of subjects presented clinical manifestations of lymphatic filariasis (e.g., pruritus). Elephantiasis of the lower limb was identified in only one subject but there was hearsay evidence of other cases involving subjects embarrassed to come forward. | lld:pubmed |
