The incidence of schistosomiasis, a parasitic infestation caused by tr
ematodes, or flukes, has decreased significantly in Egypt and other Mi
ddle Eastern countries. The education of people in the countryside is
a primary reason. The water supply in these countries is now good, and
, in most areas, women no longer use the stagnant river tributaries fo
r washing clothes. Medications, which can be used to prevent the infec
tion or kill the parasite include praziquante and metrifonate. (C) 199
