Original Article Prevalence and Intensity of Intestinal Helminth Parasites and Their Response to Treatment with Albendazole in a Rural Community in Sierra Leone

Helminth infections can be an important public health problem in most developing countries. Stool samples from five hundred and fourteen (514) participants in Gbondapi village were examined to determine the prevalence and intensity of intestinal helminths using the Kato-Katz method. The efficacy of a single dose of 200mg and 400mg albendazole in adults and subjects below and above 2 years respectively was also assessed. Seventy-nine (15.4%) of the 514 subjects were infected with at least one intestinal helminth. Data collected was analysed using Epi info statistical package. The most prevalent intestinal helminth was Hookworm (7.6%) followed by Ascaris lumbricoides (5.3%) and Strongyloides stercoralis (3.9%). The least prevalent helminth was Schistosoma mansoni (1.6%). The worm burden was generally light with mean egg counts ranging between 83 – 927eggs/gram of stool. Albendazole had an excellent safety record and found to be highly effective against Ascaris lumbricoides. In order to break the cycle of infection and re-infection in rural communities, programs embracing health education, mass treatment with albendazole, improved sanitation and the provision of protected water sources must be implemented
