Lymphatic Filariasis in Southwestern Nigerian Rural Communities: A Cross-sectional Survey of the Knowledge, Awareness, and Predisposing Factors

Abstract

BackgroundNigeria is the second most endemic country in the world for lymphatic filariasis, with control efforts often hampered by poor community awareness and involvement in intervention strategies.ObjectiveThe aim of this study was to assess the knowledge, perception, and psychosocial aspects of some residents in Nigerian rural communities about lymphatic filariasis in order to develop disease control and intervention strategies with active community involvement.MethodsA standardized questionnaire was adapted and a scale of measurement was developed. The methodology was quantitative and the study design was cross-sectional. A sample of 203 respondents was selected using a precision of 0.06.FindingsA majority (51.2%) had heard of elephantiasis but very few (9.3%) had accurate knowledge of the causes of the disease. Most people (53.2%) had no sources of information about elephantiasis, and of the few individuals that claimed availability of sources of information, information about the mode of transmission of the disease (10.0%) was the most common. Very few individuals (7.9%) believed mosquitoes were associated with elephantiasis, with 16.7% having a history of elephantiasis. The proportion of respondents who did not use mosquito netting (61.1%) was significantly higher than those who did use it (33.0%) ('P' ConclusionsThe study areas are at high risk of lymphatic filariasis. There is a need to create a knowledge-based awareness among the residents for effective management of the disease.
