Schistosomiasis mansoni and paddy-rice growing in Uganda: an emerging new problem.
In Eastern Uganda, paddy-rice growing, which has only become popular in recent years, seems to be associated with the emergence of schistosomiasis mansoni as a new problem in public health. To estimate the magnitude of this problem, a cross-sectional, baseline survey was carried out in six villages of the Kibimba Rice Scheme. The overall prevalence of Schistosoma mansoni infection was found to be 20%. The highest prevalences and intensities of infection were seen in those aged 5-29 years, with more males infected than females. An attempt was then made to identify the important factors in the aetiology of S. mansoni in this area. Odds ratios indicated that working regularly in the rice paddies, fishing with baskets, and being male were statistically associated with an increased risk of S. mansoni infection. It is clear that schistosomiasis mansoni which is emerging as a new health problem in the study area is closely linked to working in the rice paddies. Encouraging the rice farmers to wear knee-high, waterproof boots while in the fields may help control the disease.
