The prevalence of loiasis was rapidly assessed based on the World Health Organisation RAPLOA technique in 24 rural communities of the Niger Delta Area of Imo State, Nigeria using 78-82 adults per community. The rapid assessment was based on history of eye worm and Calabar swellings from individual, as well as in-depth interviews of key persons in the communities. The prevalence of loiasis in the study communities was generally low (<10%) with the RAPLOA index of restricted definition of eye worm history (REW). The highest prevalence was observed in Egbema (8.54%). The clinical manifestations was significantly higher (P<0.05) in females than in males. The history of eye worm was more among the age group 25 –34 years (4.25%) and the prevalence of calabar swelling was highest among subjects 74 years (14.11%). Farmers (6.11% {eye worm}and 7.5% {calabar swelling}) reported the highest prevalence of both manifestations among occupational groups. The epidemiological results were discussed in the context of the ongoing community directed treatment with ivermectin (Mectizan®) which can go on in the area.Keywords: Loiasis, Chrysops, Calabar Swelling, Eyeworm, RaploaNigerian Journal of Parasitology, Vol. 32 [1] March 2011, pp. 25-2
