Abstract

Objective: To assess the prevalence and clinical manifestations of lymphatic filariasis among inhabitants of the study area. Methods: A total of 1 069 persons of different age groups were examined using immunochromatographic test which detected Wuchereria bancrofti (W. bancrofti) antigens by finger prick blood collection. Physical examinations of the subjects were also carried out to check for signs of the infection on the individuals. Results: Of these, 36 (3.4%) were infected with W. bancrofti. Males showed a higher prevalence than females (4.0% vs. 2.8%, P < 0.05). Those that fell in the age group of 70 years and above were the most infected (23.8%). Regarding signs and symptoms of the disease, periodic fever was reported the most by the subjects (7.5%) followed by crawling sensation (4.9%). Periodic fever and crawling sensation tended to appear much earlier in life, while tenderness of limbs, elephantiasis and hydrocele were symptoms that showed up from the fifth decade of life. Conclusions: Our study showed that lymphatic filariasis was caused by W. bancrofti as a serious health problem in irrigation communities of Nigeria. Realistic and sustained health interventions are required to effectively control the disease in this community and other related areas of Nigeria.
