Abstract:

Numerous studies on the human intestinal parasite Capillaria philippinensis (C. philippinensis) already exist; however, systematic reviews on the parasite have yet to be made outside the Philippines since its discovery in 1963. This paper aimed to review and evaluate the current knowledge on the risk factors and prevalence of C. philippinensis outside the Philippines. A search for scientific articles published globally from 1963 to 2023 was conducted using Google Scholar, Pubmed, and ScienceDirect. The study included different types of observational study designs pertaining to the risk factors and prevalence of C. philippinensis. However, studies focused on nonhuman subjects are excluded. 106 journal articles were collated from 3 databases through a strategy that incorporated different search syntaxes. A full-paper analysis was performed, wherein the articles about the prevalence and/or risk factors of C. philippinensis were narrowed to 6 based on the inclusion and exclusion criteria. Findings suggest the emerging prevalence of C. philippinensis in Egypt [1][2][3][6], the increased risk of capillariasis in females compared to males [1][2][5][6], the transnational transmission of C. philippinensis outside the Philippines through migratory birds [4][5], and unhygienic food practices as a primary risk factor in acquiring capillaries [1][5]. Risk factors include raw fish ingestion, geographic proximity, foreign laborers, and fish-feeding migratory birds; with females, males, young adults, and the elderly being affected. There is limited evidence of existing infections in non-tropical countries.
