Introduction Soil-transmitted helminth (STH) infections remain a significant cause of morbidity worldwide. Due to the growing complexity of its transmission dynamics, which involve cross-host infections and persisting environmental contamination, the control strategies against STH continue to face drawbacks. In the Philippines, literature exploring the tripartite arm of the One Health approach remains scant; thus, to strengthen the integration of the One Health framework in the current Philippine One Health agenda, a comprehensive mapping of the local literature supporting this concept is necessary. This scoping review aims to map existing evidence on human–animal cross-host infection of STH and the extent of environmental contamination with STH in the Philippines. Methods and analysis This scoping review will follow the procedures established by the Joanna Briggs Institute methodology for scoping reviews and will be reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Eligible literature for review from 2006 to 2026 will be retrieved from PubMed, Web of Science, Google Scholar, ProQuest and Health Research and Development Information Network. Studies must contain cases of cross-host infection STH (ie, human STH infecting animals or animal STH infecting humans) or the prevalence of STH in environmental samples in the Philippines. The final selection of sources for review will begin after two independent reviewers achieve ≥75% agreement and a Cohen’s Kappa score between 0.61 and 1.00 on source selection in a pilot test. Data extraction will be performed by two independent reviewers using a modified data extraction tool adapted from JBI. Extracted data will be summarised descriptively and visually using tables and layered geographic information system maps along with a narrative summary. The search strategy was developed between October and November 2025. Data extraction is scheduled from May to June 2026, with the study anticipated to be completed by August 2026. Ethics and dissemination An ethical approval is not required for this scoping review protocol. As a comprehensive summary of cases of STH at human–animal–environment interfaces, the results of this scoping review will be presented at local and international conferences and published in a peer-reviewed, open-access journal for maximum reach and knowledge translation.
