Objective:
As part of the evaluation of control programs recommended by WHO, this study describes the local
implementation of schistosomiasis (SCH) and soil-transmitted helminthiasis (STH) morbidity control as well as water, sanitation, and hygiene (WASH) interventions post calamity. It likewise determines the challenges, areas for improvement, and good practices in SCH and STH morbidity control strategies in Haiyan-stricken areas in Eastern and Western Samar, the Philippines.
Methods:
Twenty key informant interviews and eight focus group discussions documented the implementation of SCH and STH control strategies in Eastern Visayas. Data analysis was done manually by a multi-disciplinary team.
Results:
Mass drug administration (MDA) in schools and communities was conducted for morbidity control. MDA for STH for pre-school-age children was integrated into the Garantisadong Pambata program, while a schoolbased teacher-assisted approach was used for school-age children. WASH facilities, such as sanitary toilets, were constructed through the initiatives of the local government units (LGUs) and other private sectors. Partnerships with Plan International Philippines helped in the implementation of WASH through the conduct of Community-led Total Sanitation. Health advocacies helped instill behavioral change in the community. SCH surveillance was conducted annually while STH surveillance was irregularly implemented. Data on MDA coverage were validated through Rapid Coverage Assessment before final reporting. Discrepancies were observed due to typographical errors and the inclusion of teachers and transient migrants in the reports submitted. Challenges in the implementation of MDA include delays in drug delivery, lack of human resources, non-compliance of participants, and drug unpalatability. Challenges in WASH included the lack of hand washing facilities, inaccessibility to safe water, as well as non-utility of sanitary toilets. Strengthening health advocacy and education may help address these challenges.
Conclusion
The involvement and partnership of various stakeholders such as LGUs, WASH, and veterinary
sectors, together with the academe are needed to strengthen and enhance the implementation of SCH
and STH control activities. An integrated approach may contribute to improvements in SCH and STH prevention and control of the communities in selected Haiyanstricken areas.

Objectives:
The Department of Health (DOH) aims to reduce the prevalence of intestinal parasitism and proportion of heavy intensity of infection in the country by 2022. Among the interventions is school-based mass drug administration (MDA). Regular assessment of MDA gives guidance to the DOH. The aim of this survey was to determine the prevalence of soil transmitted helminthiasis and histosomiasis among public school children ages 5 to 16 years old.
Methodology:
A cross-sectional, school-based study using multi-stage stratified cluster sampling was conducted from 2013 to 2015, covering the National Capital Region (NCR), and all provinces, except Maguindanao and Sulu. Stool samples were examined using the duplicate Kato Katz (KK).
Results:
Of the 26,171 school children with stool samples examined, 7,440 (28.4%) were infected with at least one soil-transmitted helminth (STH). Infections among male students were significantly higher than female students (31.0% versus 26.0%). Heavy, moderate, and light intensity of infections were 3.2%, 29.0% and 67.7%, respectively. STH cumulative prevalence per province ranged between 0.5% and 89.5%. Schistosomiasis infections were detected in known non-endemic provinces: Ilocos Norte, Biliran, Tawi-Tawi, Basilan, and Dinagat Islands. Majority (68%) of the infections were with single parasites but as many as five parasites were detected in one child. Infections with heterophyids were also observed.
Conclusion
While the national prevalence of schistosomiasis was less than 1.0%, the cumulative prevalence of soil-transmitted helminthiasis among school-aged children was higher than the global figure of 24.0%.

Objectives: This research study aims to conduct a systematic review and critical appraisal of the quality of the existing peer-reviewed journal literature looking into the economic evaluation of control strategies used in parasitic diseases (i.e., STH and schistosomiasis).
Methods: Database searches were conducted in Embase, Science Direct, Medline, CINAHL, Econ Lit, and Academic Search Elite, by using search keywords or phrases. Using the predefined inclusion and exclusion criteria, a review of published online articles between January 1990 and December 2012 was conducted. Aside from the set of good practice guidelines in conducting economic evaluations, assessment of the quality of economic evaluations was also carried out following the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist.
Results: Given the inclusion and exclusion criteria set by this review, we systematically reviewed thirteen shortlisted samples of economic analysis studies. The current systematic review shows a wide variety of methodological approaches across studies, including differences in the type of economic evaluation, perspective, time horizon, approach, and adjustments for timing and certainty used.
Conclusions: In general, the economic evaluation studies that have been examined in this review have complied with the set of criteria of good practice in conducting an economic evaluation and that it can be considered helpful in making decisions and in understanding the economics of controlling these parasitic diseases.

Background:
There are limited reports on foodborne trematodiases (FBT) and taeniasis prevalence and distribution in the Philippines.
Objective:
This study aimed to describe their prevalence and distribution and determine the species causing these infections in selected areas in southern Philippines.
Methodology:
The study was implemented in selected barangays in Caraga and Davao regions in southern Philippines. School-age children and adults with gastrointestinal manifestations within the last two weeks were examined using the modified Kato thick technique, while adults with cough for more than two weeks underwent sputum examination using NaOH concentration technique. The adult helminths from patients positive for FBT and/or taeniasis were processed, mounted, and stained for species identification.
Results:
Variable FBT and taeniasis prevalence across geographic areas and population groups was seen with a highly focal distribution. Heterophyidiasis was the most common FBT with a 7.5% (168 out of 2,238) prevalence. Species not known to be endemic in the area were identified including Haplorchis taichui, Opisthorchis felineus, and Echinostoma ilocanum. Variable prevalence of soil-transmitted helminthiasis and schistosomiasis was also seen.
Conclusion
The study revealed the hidden burden of FBT and taeniasis and identified species not known to be endemic in selected areas in southern Philippines. Addressing this hidden burden will require enhancing service delivery. This may be done by utilizing more accurate diagnosis, updating treatment guidelines, implementing evidence-based control interventions, and improving surveillance. Integrating control programs, for instance, integrating FBT and taeniasis control with STH and schistosomiasis control, and integrating paragonimiasis control with the national TB program, may also help in optimizing resources.

Intestinal helminth infections caused by soil-transmitted helminths and schistosomes bring about the greatest burden of disease in poverty-stricken areas in the developing world. The most vulnerable group and the most significant contributors to disease transmission are the school-age children. While awaiting major improvements on sanitation, the recommended strategy for helminth control is school-based, teacher assisted, mass drug administration (MDA). However, millions of individuals worldwide remain afflicted with these diseases, and the Philippines is no different from many of the developing countries. The overall objective of this paper is to review current Philippine control programs and initiatives and offer evidence based recommendations for improvement. Discrepancies between parasitologic parameters and drug coverage rates pose significant challenges in the control and prevention of helminth infections in the country. School-based MDA may be scaled up after successful local initiatives, where teachers have direct participation in drug administration. There is also a need to involve the social science sector to help address the behavioral aspects of helminth control. Moreover, monitoring and evaluation of interventions through identification of success parameters will contribute to the optimization of school-based helminth control, and to strategies towards effective control of intestinal helminth infections as a public health problem in the country.

Schistosomiasis is still a public health burden in the Philippines. Chronic infection with Schistosoma japonicum, the only species endemic in the Philippines, clinically manifests itself in a wide variety of pathologies usually correlated with the anatomical site of adult worm activity and deposition of eggs. One of the documented ectopic sites for Schistosoma ova is the appendix. A rare sequela of this is acute appendicitis and an even rarer consequence is progression to appendiceal rupture leading to acute peritonitis. We present a case of a 27-year-old Filipino residing in Davao City but born in Agusan Province who initially complained of right lower quadrant abdominal pain but presented at the emergency room with generalized abdominal tenderness with signs of peritoneal irritation. Exploratory laparotomy with an infraumbilical incision revealed ruptured appendicitis with periappendiceal abscess formation and appendectomy was subsequently done. Schistosoma infection of the appendix was subsequently established by histopathological analysis. Furthermore, features observed suggest an atypical pathogenetic process contrary to the putative pathogenesis of most cases of acute appendicitis.
