Of 2,239 screened records, 2,139 met inclusion criteria. Ten predefined variables were extracted and thematically coded using Python-assisted and manual validation.ResultsObservational designs constituted the largest share (38.9%), followed by modeling studies (34.8%). Respiratory (36.2%) and vector-borne (34.9%) infections were the most frequent topics. Composite climate indicators were used in 29.8% of studies. Only 27% contained explicit policy recommendations, and spatial modeling appeared in 13%. Early warning systems were mentioned in 57.5% (n = 1,230) of articles, whereas socioeconomic determinants were included in only 13.4%, mostly from high-income settings. Low-income and climate-vulnerable regions remained markedly underrepresented.ConclusionsDespite rapid expansion of climate-health research over the past 15 years, key deficits persist in methodological diversity, policy translation, and regional equity. Priorities for the next phase include longitudinal designs, integration of socioeconomic indicators, and harmonized One Health frameworks linking surveillance and adaptation. Strengthening these dimensions is essential for shifting global preparedness for climate-sensitive infectious diseases from reactive to preventive.Clinical trial registrationNot applicable.eninfo:eu-repo/semantics/openAccessClimate ChangeInfectious DiseasesScoping ReviewPublic Health PolicyThematic AnalysisArticle
