Human fascioliasis in an Egyptian village: prevalence and some epidemiological determinants.
A cross-sectional survey was conducted in Abis area, 15 kilometers south east of Alexandria city, to determine the prevalence of human fascioliasis and to study some of the epidemiological determinants which may affect the infection. A specially designed questionnaire interview was completed, and a total number of 3475 stool samples were examined. The results revealed a prevalence rate of fascioliasis of 11% in the studied area which was only second to S. mansoni. The prevalence of infection was significantly higher among females in general and specifically in the age group 5 to less than 15 years and 25 to less than 35 years. Family aggregation of fasciola infection was noticed among the studied group. The prevalence and also the risk of infection were significantly higher among children whose mothers were infected. They were, however, insignificantly higher among illiterate, single males, and low social class group. In addition, the prevalence and risk of infection were significantly higher among individuals obtaining their raw green leafy vegetables from multiple sources. From the results it was concluded that human fascioliasis is an important public health problem in Abis area with increased risk of spread of infection to Alexandria city through raw green leafy vegetables which represent the main source of infection.
