Epidemiological studies on schistosoma haematobium infection in coastal area of kenya diurnal fluctuation of cercarial density in natural water and measurement of the risk of infection after control by cercariometry






Tropical Medicine 29(2): 81-86

Epidemiological studies on schistosoma haematobium infection in coastal area of kenya diurnal fluctuation of cercarial density in natural water and measurement of the risk of infection after control by cercariometry

Cercariometry was carried out at 2 major water contact sites in an endemic area of urinary schistosomiasis, before and after the introduction of control measures against the disease. The natural water was examined for the presence of cercariae by filtration technique at one hour interval during the daytime. Before the control measures performed, at one of the sites, 567 cercariae were detected in 90 liters of water examined and the pattern of cercarial density was found to be diurnal with the highest density at noon. Six months after the implementation of control measures with a combination of treatment with metrifonate and provision of piped water, 354 cercariae were recovered from 90 liters of water examined and the pattern was also diurnal. At the another site, on the other hand, only 2 cercarie were found in 180 liters of water sample before the control and no cercariae were detected after the introduction of control measures. Evaluation of the impact of control measures on the risk of contracting the infection was discussed.
