Awareness, Knowledge and Prevention Practices Related to Lassa Fever Among Residents of Rural Communities in Southwest Nigeria: Implications for Prevention and Control

Abstract Background: Lassa fever (LF) is a haemorrhagic illness caused by Lassa virus. The primary reservoir of the virus is the multimammate rat, Mastomys natalensis. More than 3,000 laboratory-confirmed cases of Lassa fever and over 800 deaths have been recorded in Nigeria. This could be attributed to poor rat control and poor sanitation especially in the rural communities where the rats are often found. Increasing awareness and health education about LF have been advocated for its prevention and control. This study investigated the level of awareness, knowledge and prevention practices related to LF among residents in rural communities within Iwo and Ayedire Local Government Areas, Osun State, southwest Nigeria sequel to an awareness campaign. Methods: Structured questionnaire was administered within rural communities in Iwo and Ayedire and 675 participants responded for the survey by a random sampling technique. Descriptive statistics, Chi-square test of association ( p = < 0.05) and logistic regressions were used to determine associations between demographic variables, level of knowledge and prevention practices. Results: The average age range was 25-39 years, 365 (54.07%) were male, 270 (40%) were married, 199 (29.48%) had up to secondary school education and 536 (79.41%) have heard about LF before. Respondents in Iwo town were more aware of LF than respondent from Ayedire. Only 3 (0.44%) had good knowledge of the transmission and symptoms of the disease and 304 (45.04%) do not have effective means of preventing rats into their homes. About 296 (43.85%) will go to a hospital if symptoms occur, while 118 (17.48%) will do self-medication. Forty-four (6.52%) were aware of good prevention practices. Logistic regression analysis showed that respondents aged 25–39 years were significantly more aware of Lassa fever than other age groups. Educated and married respondents showed significant relationship with good prevention practices than those without education and were not married. Conclusions: Although, the awareness of LF among the respondents was high, only very few had good knowledge of the transmission and symptoms of the disease. Therefore, it is important for the people to be well informed about the disease and good prevention practices in order to curtail the spread.
