The ecological changes caused by projects for the development of water resources are known to affect the epidemiology of water-related diseases. The effects of the construction of the Diama dam (completed in 1986) in the Senegal River on the epidemiology of malaria, urinary and intestinal schistosomiasis, diarrhoea and dysentery were investigated in four districts in northern Senegal. To make allowance for any general trend in reported morbidity (caused by changes in demography or the healthcare system), the numbers of cases of these illnesses reported by the basic healthcare facilities before and after the completion of the dam were compared with those of respiratory disease. Prior to the construction of the dam, malaria was the most encountered water-related disease in the medical records of all districts, followed by diarrhoea, dysentery and urinary schistosomiasis. This order remained the same after the completion of the dam. Despite the optimism of health-assessment reports prepared prior to the construction of the Diama dam, the unexpected appearance and spread of intestinal schistosomiasis as well as an increase in the incidence of urinary schistosomiasis have aggravated public health in the Senegal River basin. It remains to be judged whether the economic benefits of the dam will counterbalance its adverse effects

Studies on the compatibility between Bulinus truncatus and Schistosoma haematobium from various areas in the Senegal River basin (SRB) were carried out, to investigate the role of B. truncatus in the epidemiology of urinary schistosomiasis in Senegal. The results show that B. truncatus from the Lower Valley is not compatible with S. haematobium from the Middle Valley. Interestingly, the study reveals that B. truncatus from the Upper Valley is compatible with S. haematobium from the same area, and that S. haematobium from the Middle Valley is compatible with B. truncatus from the Lower Valley. Bulinus truncatus naturally infected with S. haematobium have been collected from the Upper Valley of the SRB. These results indicate that B. truncatus is involved in the urinary schistosomiasis in Senegal.
