An intestinal parasite survey was conducted in the town of Victoria, Oriental Mindoro, Philippines in 1978 in order to estimate the current schistosomiasis situation in this area of the Philippines and Schistosoma japonicum eggs were detected in 20% of 1058 fecal specimens examined. The prevalence was more than twice as high as had been previously estimated. Infection rates were higher in males than in females, 26 versus 15% and age-wise were infrequent in young children (8%) and moderately common in other age groups (20-32%). Other intestinal helminths and protozoan parasites of man in Oriental Mindoro were: Ascaris lumbricoides, Trichuris trichiura, Necator americanus, Enterobius vermicularis, Strongyloides stercoralis, Capillaria sp, taenid tapeworm, echinostome, dicrocoelid and opisthorchiid trematode, Entamoeba histolytica, Entamoeba coli, Endolimax nana, Giardia lamblia, Iodamoeba bütschlii, Trichomonas hominis and Chilomastix mesnili.
