Studies on the sero-epidemiology of endemic diseases in Libya

Abstract
An ELISA system showed a positive rate for Schistosoma monsoni infections of 33·4% in Tauorga schoolchildren; qualitative stool examination detected only 6·9%. Subsequent sampling of the school population indicated that a mollusciciding programme involving the major water body in the area had prevented any overall increase in prevalence and had apparently produced a decrease in prevalence in certain locations. New housing, piped water, sanitary disposal of wastes and health education were additional favourable factors.
