Mapping distribution of loiasis is a pre-requisite for planning National Eradication Programme for Onchocerciasis. The knowledge of the disease distribution in Imo state Nigeria was poor and its current significance as a public health problem. Epidemiological mapping was undertaken to assess loiasis based on the W.H.O. RAPLOA technique in 20 rural communities of the two local government areas of Imo State, Nigeria respectively. The rapid assessment was conducted based on history of eye worm and Calabar swellings from individual as well as in-depth interviews of key persons in the communities. A total of 1,474 individuals aged between 15 years and older were taken from the same group. All the communities had RAPLOA rates of less than 40% WHO standard. The clinical manifestation was significantly higher (P < 0.05) in females than males. The history of eye worm and Calabar swelling was more among age group 31-40 years with (32.2%) and (23.7%) respectively. Farmers (30.07%) had the highest prevalence in occupational groups. Findings from this study indicate that the prevalence of infection is less; these data would be very useful in planning & prioritizing intervention activities. Concerted and coordinated mass enlightenment should be sustained to eradicate the pocket of active case and eliminate all sources of infection to Chrysops fly vectors.
