A total of 1,243 Ezza people living in 10 communities of Ebonyi State, eastern Nigeria were examined between July 2002-January 2003 for lymphatic filariasis. This is the first time a filariasis survey due to Wuchereria bancrofti has been carried out in this state. Of the 1,243 persons examined, 210 (16.9%) had W. bancrofti microfilariae. Infection varied significantly among communities and ages (p<0.05) but not sex-related (p>0.05). The Ezza people are predominantly farmers and professional hired labourers. There was a close association between microfilaria rate and microfilaria -density in various age groups (r = 0.812; p<0.01). Microfilaria density is an important measure in the epidemiology, treatment and control of human filarisis in this endemic foci. Clinical signs and symptoms of the disease include elephantiasis, hydrocoele, dermatitis and periodic fever. Clinical symptoms without microfilaraemia and microfilaraemia without clinical symptoms were also observed. Of 1,603 mosquitoes dissected, Anopheles gambiae, An. funestus and Culex quinquefasciatus showed infectivity rates of 6.3%, 5.1% and 6.0% respectively. The affected persons and other key informants are unaware of the cause of the disease and attributed it to witchcraft, violation of taboo, bad water and food. Intervention strategies to be integrated into the on-going Community-Directed Treatment with Ivermectin (CDTI) project are discussed.

Studies on vesical schistosomiasis and its snail vectors were carried out between October 2001–May 2002 among rural Ezza farmers inhabiting the southwestern border of Ebonyi State, Nigeria. The people are predominantly farmers. Of the 2,104 urine specimens examined in 10 communities, 466 (22.1%) comprising 305 (23.7%) men and 161 (19.7%) women were infected with visible haematuria as the predominant presenting symptom. Ezza people associate bloody urine with sexually transmitted diseases. There were no significant differences in the prevalence rates amongst various villages and sexes (p>0.05). There was a gradual increase in the disease prevalence as the subjects’ age increases. About 78.3% of the infected persons are aged 0–20 years. Statistical analysis revealed that the prevalence, intensity and visible haematuria were significantly more (p<0.05) in subjects under the age of 20 than subjects above 20. Among the infected population, 183 (39.3%) and 283 (60.7%) were excreting 50 eggs/10 ml urine and above 50 eggs/10 ml urine respectively. Lack of visible haematuria is a more valid indicator of the absence of vesical schistosomiasis. Of the various snails collected during malacological survey, mainly B. globosus were infected. Possible control measures are discussed.
