Studies on the endemicity of dracunculiasis, it's transmission pattern and ecology of cyclopoid copepods in Ezza North Local Government Area of Ebonyi State Nigeria were carried out between January and December 2001. Of the 2226 persons examined in eight communities, 426 (19.1%) were infected. This included 24 (18.3%) and 202 (20.2%) males and females respectively. The highest prevalence (47.9%) was recorded in Iyere community followed by Ekka (43.9%) with Umuoghara community as the least (12.4%). Although the overall male prevalence was lower than the female, it was not statistically significant (p>0.05). Infection prevalence in school-aged children (1-24 years) was significantly higher than the older persons (p63% of all the copepods found. This was followed by Thermocyclops oblongatus nigerianus with M. ogunnus Onabamiro as the least. Only T. oblongatus nigerianus and M.aequatorialis were infected with D. medinensis larvae. The ecology of the vector in relation to the epidemiology of the disease in the area is discussed. Keywords: dracunculiasis, endemicity, transmission pattern, ecology, cyclops, Nigeria International Journal of Natural and Applied Sciences Vol. 1(1) 2005: 57-67
