The periodic collection of parasitologic and morbidity indicators is recommended by the World Health Organization (WHO) to monitor schistosomiasis (SCH) and soil-transmitted helminthiasis (STH) control programs. In 2017, the DOH-CHD VIII (Department of HealthCenter for Health Development Region 8 Office) in collaboration with UP-NTDSG (the University of the Philippines Neglected Tropical Diseases Study Group) conducted a monitoring activity aimed at determining [1] the prevalence and intensity of SCH and STH; [2] seroprevalence of SCH; and [3] prevalence of stunting, underweight, wasting, and anemia in pre-school-age children (PSAC) and school-age children (SAC) in selected municipalities in the province of northern Leyte, the Philippines as part of monitoring the local implementation of SCH and STH control programs. Stool samples were collected, processed using the Kato-Katz technique, and examined through microscopy. Blood specimens collected from SAC were tested for the presence of Schistosoma japonicum antibody using the IgG ELISA (enzyme-linked immunosorbent assay) kit. Data on anthropometric measurements and hemoglobin levels were collected with adherence to WHO guidelines. Secondary analysis of the gathered data showed that SCH prevalence in SAC was 3.1%, but SCH seroprevalence was 83.1%. Although STH prevalence met the national target of 50%, heavy-intensity STH prevalence remained higher than the global target of 2%. The overall prevalence of underweight, stunting, and wasting were 19.2, 38.0, and 10.6%, respectively. STH was significantly associated with stunting in PSAC (p
