Prevalence and Transmission of Soil Transmitted Helminths among Farmers Living Along the Metropolitan Section of River Kaduna, Nigeria

Soil-transmitted helminths (STHs) are one of the world’s most important causes of physical and intellectual growth retardation. The study was conducted to determine the prevalence and transmission of soil-transmitted helminths among farmers living along the metropolitan section of river Kaduna, Nigeria. Two billion people are infected globally and four billion at risk of infection to STH. Nigeria ranking first globally, accounts for about 156 million cases of STH. A total of 210 stool samples were randomly collected from farmers of seven (7) different farms located along the riverbank. The stool samples collected were examined for STHs using direct wet mount and formal ether sedimentation techniques. Questionnaires were administered to the farmers to assess their hygiene, sanitation, and health maintenance. The prevalence of STH based on the farmers' age and gender was also determined. Out of the total stool samples collected, 81(38.6%) were infected with at least one out of the four STH eggs. The eggs of hookworm and Ascaris lumbricoides were the only helminths eggs detected. Hookworm was found to have a prevalence of 54.3% while A. lumbricoides have a prevalence of 45.7%. Strongyloides stercoralis and Trichuris tichuira both were found to have 0% prevalence. The risk factors such as personal hygiene, sanitation and health maintenance were found to have a significant influence on the prevalence (38.6%) (P<0.05) of STH among the farmers. The age prevalence shows that group 10 – 25 have the highest prevalence of 81.3% while age 36 – 45 shows the lowest prevalence of 2.4%. The gender prevalence shows that male farmers have the highest prevalence of 41.4% out of the total infected farmers (81). The findings could be as a result of farmers’ hygiene, sanitation and health maintenance on their various farms and their use of contaminated farm tools which acts as a medium for the transmission of the parasite eggs, while the younger age group work more hours than the older age group and the male farmer spends more time in the farm than the female.
