ABSTRACT
Food-borne trematodes (FBTs) are emerging infections and of substantial public health importance but are among the most ignored of the neglected tropical diseases (NTDs) in terms of attention, research and funding. A review of the status of FBTs in the Philippines based on the best available local and national information may provide a basis for the formulation of appropriate prevention and control measures most suitable for its setting. This review presents a summary of the key features of FBTs and the epidemiologic pattern of FBTs in the Philippines and on the current measures being done for infection control and prevention in other countries. Paragonimiasis, echinostomiasis, and heterophyidiasis are still prevalent in the Philippines with food preparation and hygiene practices and presence of infected intermediate hosts as major determinants of epidemiology and disease burden. Control and prevention of food-borne trematodes may be best achieved with political will, coordinated efforts among responsible public sectors, and involvement of relevant communities.

Objectives. This study aimed to describe baseline and follow-up prevalence and intensity of soil-transmitted helminth (STH) infections, nutritional status and school performance of school-age children in Cebu City. By measuring these parameters, it also aimed to monitor the progress of a local government unit-led, school-based, schoolteacher-assisted deworming initiative. Methods. Grade three and grade four pupils from two selected school districts in Cebu City were chosen as participants. Kato-Katz technique was used to assess helminth infections. All positive slides and 10% of all negative slides were re-examined blindly by a reference microscopist for quality control. Secondary anthropometric and school performance data were also obtained from the Department of Education. Results. Baseline results showed cumulative prevalence and prevalence of heavy intensity infection of 73.1% and 44.3%, respectively, which were significantly lower during follow-up at 56.5% (p < 0.0001) and 26.5% (p < 0.0001), respectively. School performance improved in District B, with an 8.8% increase in mean percentage score from baseline to follow-up. There was no marked difference between baseline and follow-up proportions of pupils with below normal weight-for-age and height-for-age. Conclusions. The positive results merit continuation of the school-based STH control initiative in Cebu City. Improvements in water supply and sanitation, promotion of good hygiene and health education are important in minimizing risks of infection and re-infection.
