Abstract (English)
Amoebiasis is a gastrointestinal infection mainly caused by Entamoeba spp., which remains a global health problem and is particularly common in tropical regions with poor sanitation and contaminated water. Despite the risk, there is limited information and research on the current prevalence of Entamoeba spp. infections in Manila. This study aimed to determine the prevalence of Entamoeba spp. infection among residents of Barangay 710, Malate, Manila, and to describe the demographic characteristics of the participants and explore their possible relationship with infection status. A descriptive cross-sectional study was conducted in Barangay 710 where consenting participants were interviewed and provided a stool kit. The samples were processed using the Formalin–Ether Concentration Technique (FECT) and direct wet mount with iodine staining for Entamoeba spp. cysts and trophozoites, with two replicates per processing method. Descriptive statistics were used to summarize the demographic characteristics and calculate infection prevalence in the study population. Among the 18 collected stool samples, none were positive for Entamoeba spp., yielding a prevalence of 0%. This absence of infection indicates minimal or no ongoing transmission of amoebiasis within the community. The findings suggest that effective sanitation infrastructure, access to clean water, and established hygiene practices have contributed to reducing the risk of intestinal parasite infections. Furthermore, proximity to health facilities that regularly implement deworming and health education programs likely reinforced preventive measures. Overall, the results emphasize the importance of continuous sanitation, hygiene, and public health efforts in sustaining a parasite-free community.

Abstract (Filipino)
Ang amoebiasis ay isang impeksiyon ng sistemang panunaw na dulot ng Entamoeba spp. na nananatiling suliraning pangkalusugan, lalo na sa mga lugar na may kakulangang sanitasyon at kontaminadong tubig. Gayunpaman, kakaunti pa rin ang datos tungkol sa paglaganap ng Entamoeba spp. sa Maynila. Layunin ng pag-aaral na ito na matukoy ang prebalensya ng impeksiyon sa Barangay 710, Malate, Manila, at ilarawan ang mga demograpikong katangian ng mga kalahok upang makita ang posibleng kaugnayan nito sa kanilang katayuan hinggil sa impeksiyon. Isinagawa ang isang deskriptibong cross-sectional na pag-aaral kung saan ang mga boluntaryong kalahok ay isinailalim sa panayam at binigyan ng stool kit. Ang mga nakolektang muwestra ay inanalisa gamit ang direct wet mount na may iodine staining at Formalin–Ether Concentration Technique (FECT), na may tig-dalawang ulit sa bawat pamamaraan. Gamit ang deskriptibong estatistika, naibuod ang datos at kalkulahin ang prebalensya ng impeksiyon. Mula sa 18 muwestra ng dumi na nakolekta, wala ni isa ang nagpositibo sa Entamoeba spp., na nagresulta sa 0% na prebalensya. Ipinahihiwatig nito na maaaring walang aktibong pagkalat ng amoebiasis sa komunidad. Karamihan sa mga respondente ay may edad 31 pataas, babae, at nakatira sa mga tahanang may 1–4 na miyembro. Marami ang gumagamit ng mineral na tubig mula sa mga purification stations at may pribadong palikuran. Ipinakita ng mga natuklasan na ang maayos na sanitasyon, malinis na tubig, at mabuting gawi sa kalinisan ay epektibong nakapagpapababa ng panganib sa parasitikong impeksiyon. Dagdag pa rito, ang akses sa mga pasilidad ng kalusugan o pagamutan na nagsasagawa ng pagpupurga at edukasyong pangkalusugan ay nakatulong sa pagpapatibay ng pag-iwas. Binibigyang-diin ng resulta ang kahalagahan ng patuloy na sanitasyon, kalinisan, at suporta ng pampublikong kalusugan upang mapanatili ang isang ligtas at malaya sa parasito na komunidad.
