Abstract
The seasonality of infection of Bulinus (Ph.) globosus, the snail host of Schistosoma haematobium is reported. The pattern of snail infection was shown to vary with the type of habitats. The cercarial “transmission potential” was calculated based on the number of infected snails and the level of cercarial production. It is consequently assumed that the transmission pattern varies with season and habitat type. Dry season transmission potential was found to be high in running water habitats while low in stagnant water habitats. In the wet season, the reverse seems to be the case. The implication of these observations in the epidemiology of urinary schistosomiasis and in planning its control in the area is discussed.
