Abstract BackgroundHelminth infections among children remains a public health concern despite continued deworming activities conducted in all public schools nationwide. Access to improved sanitation facilities not only leads to continued practice of open defecation predispose children to this intestinal parasitic infection. This study aim to characterize the sanitation situation and practices among households as well as their deworming practices and associate it with the prevalence in two rural communities in San Pascual, Masbate, Philippines. MethodsA survey of 234 randomly selected households from the two barangays was conducted followed by stool screening using Kato-Katz method from 586 children and adolescents below 18 years old was done in June 2019. ResultsThe survey showed that 33.28% of households do not have access to sanitary toilet and open defecation was practiced by 53.92% of surveyed households. More than half of the households (60.75%) surveyed also reported “poso” as their source of drinking water. The survey also revealed that households have high scores in the knowledge, attitude, and practices or KAP section of the survey. The over-all cumulative prevalence rate was at 41.6% moderate to light intensity infection rate. ConclusionAmong the variables tested, only the source of drinking water, attitude scores, and MDA participation showed association with having helminth infection among children. The study highlights the importance of advocating multi-sectoral approach in addressing persistent public health issues like the intestinal parasitic infections among children. Moreover, this study provides valuable information needed to support strategies like community-led total sanitation or CLTS as a potential strategy addressing both sanitation and public health dilemma.

Foodborne Trematodes

Foodborne trematodiasis is a neglected tropical disease (NTD) caused by zoonotic trematodes that persist mainly in impoverished areas in the Asia-Pacific region. Globally, about 2 million disability life years (DALYs) are lost due to these parasitic infections. Four groups of foodborne trematodes are known to cause significant illness: fish-borne liver fluke infections caused by Opisthorchis and Clonorchis spp.; water vegetable-borne Fasciola spp. infections; crustacean-vectored paragonimiasis; and those caused by intestinal trematodes. In the Philippines, endemic foodborne trematodes of public health concern include Paragonimus westermani, some members of Heterophyidae and Echinostomatidae, and Fasciola hepatica/ F. gigantica. Opisthorchis viverrini and Clonorchis sinensis have also been reported in the country. Data on the epidemiology of these zoonotic illnesses remain scarce and in need of research attention in the Philippines. Culturally rooted eating behaviors in endemic areas are important risk factors to acquiring and perpetuating foodborne trematodiasis. The combination of mass drug administration (MDA), provision of clean water and maintenance of good sanitation and hygiene (WASH), community health education towards modification of risky behaviors, surveillance, and veterinary public health interventions have been shown to be effective in combatting these zoonotic parasitoses. An integrated control and prevention program anchored on the One Health paradigm is a must to address these illnesses. This paper aims to review the biology and epidemiology of, and public health interventions against zoonotic foodborne trematodiasis in the Philippines and its neighboring countries.

Drinking Water Sources

Water-borne parasitic infections have become a source of concern in recent times due to the contamination of various water sources. A survey on the parasitic contamination of local drinking water sources in Aba metropolis was carried out between August and October 2018. This was done to evaluate the extent of contamination of these water sources and their public health implications. A total number of eighty (80) water samples were investigated from five (5) major water sources within the study area using the standard sedimentation method and examined for parasite cysts, eggs and larvae. Physical/macroscopic examination was done to determine the pH, colour, odour, temperature and presence/absence of particles. Among the water sources analyzed, stream water samples had the highest rate of parasite contamination 27 (44.3%) followed by river water 14 (22.9%) while the least contaminated was borehole 7 (11.5%). Rainwater was found free from parasitic infestation. The differences in the level of contamination among the water sources analyzed were found to be statistically significant (P<0.05). Five parasites Entamoeba histolytica, Giardia lamblia, Ascaris lumbricoides of Entamoeba coli and Hookworm were observed. Each of the sample sources except rainwater harbored at least one of these. Among these parasites, Giardia lamblia had the highest rate occurrence of 15 (24.6%), followed by Entamoeba histolytica 14 (22.9%) and the least frequently occurring parasite was hookworm 8 (13.1%). Most of the identified water sources are utilized by the populace who lack access to potable water. The detection of protozoan and helminthic parasites in drinking water sources is a serious public health concern, hence the proper implementation of a supply of safe drinking water is vital.

Background: Intestinal parasitic infections are the one of the most common health problems in developing countries. Objective: A number of patients die annually due to complications caused by these parasites.Therefore, the aim of this study was to investigate the rate and type of parasitic infections, determine the factors affecting them in Ilam city and also provide strategies to prevent them.In this descriptive cross-sectional study conducted in one of the Ilam labs in 2016, 417 stool specimens were randomly collected. All specimens were examined using direct and ethanol formaldehyde.Suspect specimens were examined using Trichrom staining. Demographic information was also recorded in a questionnaire, and finally the results were analyzed using statistical software SPSS 20.The data were then compared with Chi-square test. Results: Out of the 417 patients examined, 59 (14.1%) were infected with intestinal parasites. The type of parasitic infection in 9.4% was Blastocystis hominis, 3.6% Entamoeba coli, 0.5% Entamoeba histolytica, 0.5% Giardia and 0.2% Trichomonas hominis. Conclusion: Despite the improvement of public health, parasitic infections are still considered as one of the health problems in the city of Ilam. Therefore, proper planning, public health education, raising the level of health in the area and the provision of safe drinking water are some of the ways to reduce parasitic infections in the region.

Intestinal Parasitic Infection

Intestinal parasitic infections have always been an important public health problem in the tropics particularly in developing countries such as Nigeria for example. A cross-sectional survey involving 440 schools going children of both sexes aged 6 - >12 years was conducted in 4 primary schools at a different location in Doma Local Government Area (LGA) of Nasarawa State, Nigeria, between September 2015 to February 2016 to determine the prevalence of intestinal parasites. Of the 440 samples examined 155 (35.22%) were infected with different intestinal parasites. The parasites observed included Entamoeba histolytica (6.59%), bookworm (5.22%), Ascaris lumbricoides (53.40%), Trichuris trichiuria (0.45%), E. coli (4.77%) and mixed infection of Ascaris lumbricoides and hookworm (7.27%) with Ascaris lumbricoides having the highest prevalence. Doma south primary school 38 (34.54) Islamiyya nursery/primary school and Doma west primary school had the lowest prevalence with 36 (32.72%) and 34 (30.90%) respectively. An overall prevalence of (35.22%) intestinal parasitic infection in school going children is moderately high and of public health concern. There is need to intensified integrated control measure to reduce or completely eradicate the intestinal parasitic infection in school pupils.

Polyparasitism is widespread in many communities in Sub-Saharan Africa. However, there is paucity of data on polyparasitism in infants and preschool-aged children (IPSAC), to inform policy developments. Therefore, a survey of 1110 consented IPSAC was undertaken in Egbedore Local Government Area (LGA), Osun State, Nigeria, to determine the prevalence of polyparasitism in IPSAC in ten randomly selected rural communities. Fresh stool and blood samples were collected and processed for intestinal parasites and malaria infection. Mothers/caregivers were interviewed using a structured questionnaire to obtain demographic data of their IPSAC and to document knowledge, attitude, and practice (KAP) on parasitic infections. Data obtained through the questionnaire were analyzed using EpiData version 3.1, while parasitological data were analyzed using Statistical Package for Social Sciences (version 20.0). Descriptive statistics were computed for demographic data and association which were tested using bivariate analysis at a 95% confidence level while significance was set at p<0.05. The results showed that 349 (46.29%) were infected with a single parasite. Infants and preschool-aged children infected with double, triple, and quadruple parasites are 268 (35.54%), 122 (16.18%), and 15 (1.99%), respectively. The prevalence of polyparasitism is 405 (53.71%). Although females (54.07%) were more infected than males (45.93%), there was no significant difference (p>0.05) observed. Significantly (p<0.05) more preschool children (65.93%) harbour more infections than the infants do (34.07%). Ara community (14.81%) had the highest cases of polyparasitized IPSAC, but no significant difference (p>0.05) was observed across the communities. Double parasitic infection of Plasmodium falciparum and Ascaris lumbricoides (30.12%) and triple parasitic infection of P. falciparum, A. lumbricoides, and T. trichiura (14.81%) were the most common forms of polyparasitism encountered in the study. This study showed that polyparasitism is a burden in IPSAC and needs further investigation.

SUMMARYWaterborne illness related to the consumption of contaminated or inadequately treated water is a global public health concern. Although the magnitude of drinking water-related illnesses in developed countries is lower than that observed in developing regions of the world, drinking water is still responsible for a proportion of all cases of acute gastrointestinal illness (AGI) in Canada. The estimated burden of endemic AGI in Canada is 20·5 million cases annually – this estimate accounts for under-reporting and under-diagnosis. About 4 million of these cases are domestically acquired and foodborne, yet the proportion of waterborne cases is unknown. There is evidence that individuals served by private systems and small community systems may be more at risk of waterborne illness than those served by municipal drinking water systems in Canada. However, little is known regarding the contribution of these systems to the overall drinking water-related AGI burden in Canada. Private water supplies serve an estimated 12% of the Canadian population, or ~4·1 million people. An estimated 1·4 million (4·1%) people in Canada are served by small groundwater (2·6%) and surface water (1·5%) supplies. The objective of this research is to estimate the number of AGI cases attributable to water consumption from these supplies in Canada using a quantitative microbial risk assessment (QMRA) approach. This provides a framework for others to develop burden of waterborne illness estimates for small water supplies. A multi-pathogen QMRA ofGiardia, Cryptosporidium, Campylobacter, E. coliO157 and norovirus, chosen as index waterborne pathogens, for various source water and treatment combinations was performed. It is estimated that 103 230 AGI cases per year are due to the presence of these five pathogens in drinking water from private and small community water systems in Canada. In addition to providing a mechanism to assess the potential burden of AGI attributed to small systems and private well water in Canada, this research supports the use of QMRA as an effective source attribution tool when there is a lack of randomized controlled trial data to evaluate the public health risk of an exposure source. QMRA is also a powerful tool for identifying existing knowledge gaps on the national scale to inform future surveillance and research efforts.

Abstract The current public health crisis has radically altered the social and civic involvement in Southeast Asia. Although the virus has shifted the landscape of engagement, it has not dampened the enthusiasm of the public. In 2020–2021, more people than ever seem to be paying attention and even getting involved in activism. Many dramatic events happened during the coronavirus crisis such as from protests in support of the Black Lives Matter movement, public activism around the environment, economic inequality, authoritarianism and human rights violations. In Indonesia, the Philippines, Malaysia, Thailand and just recently Myanmar. The journal has lately published about the ‘Relationship of George Floyd protests to increases in COVID-19 cases using event study methodology’ and it has rightly expressed that the Centers for Disease Control and Prevention (CDC)-recommended social distancing guidelines must be followed in a protest situation. In response to the situation of social activism in Southeast Asia, one must follow the CDC-recommended and World Health Organization (WHO) guidelines in the Region. Although protesting is an individual human right, one must also be cautious and be aware of the deadly virus since we are still in a pandemic and the COVID-19 virus continues to mutate.

Abstract Raw and partially treated wastewater has been widely used to maintain the global water demand. Presence of viable helminth ova and larvae in the wastewater raised significant public health concern especially when used for agriculture and aquaculture. Depending on the prevalence of helminth infections in communities, up to 1.0 × 103 ova/larvae can be presented per litre of wastewater and 4 gm (dry weight) of sludge. Multi-barrier approaches including pathogen reduction, risk assessment, and exposure reduction have been suggested by health regulators to minimise the potential health risk. However, with a lack of a sensitive and specific method for the quantitative detection of viable helminth ova from wastewater, an accurate health risk assessment is difficult to achieve. As a result, helminth infections are difficult to control from the communities despite two decades of global effort (mass drug administration). Molecular methods can be more sensitive and specific than currently adapted culture-based and vital stain methods. The molecular methods, however, required more and thorough investigation for its ability with accurate quantification of viable helminth ova/larvae from wastewater and sludge samples. Understanding different cell stages and corresponding gene copy numbers is pivotal for accurate quantification of helminth ova/larvae in wastewater samples. Identifying specific genetic markers including protein, lipid, and metabolites using multiomics approach could be utilized for cheap, rapid, sensitive, specific and point of care detection tools for helminth ova and larva in the wastewater.
