The use of well developed and adequately distributed Primary Health Care (PHC) centers for the control of schistosomiasis in the infested areas in the Central Province of Saudi Arabia around the capital city of Riyadh has proven feasible producing satisfactory results. The number of inhabitants examined for schistosomiasis increased from 10688 in 1984 to 106579 in 1988, and the prevalence dropped from 9.3% in 1984 to 0.6% in 1988. Currently the majority of inhabitants of infested villages are examined in the PHC centers once a year and cases are treated. Snail control is also done by centres.
