An ecological study on the epidemiological trends of predominant IIDs\u2014hand, foot, and mouth disease (HFMD), viral diarrhea (DV), and non-viral diarrhea (DN)\u2014was conducted in Shenzhen, China (2012\u20132022), aiming to elucidate the associations of meteorological factors, including extreme temperatures, seasonal variations, and temperature-humidity interactions with IID transmission, and to establish a monitoring and early warning framework. We assessed temperature-related morbidity\u2019s short-term lagged effects, long-term cumulative impacts, and seasonal patterns using distributed lag non-linear models, finding that high temperatures (30\u00b0C) significantly increase HFMD and DN risks, low temperatures (13.8\u00b0C) worsen DV infections, and high temperatures have specific pathogenic effects on individuals aged 0 and over 20 years. Humidity-mediated seasonal variations in the incidence of IIDs were identified within equivalent temperature ranges. Generalized additive models (GAMs) further decoded the incidence patterns of IIDs across population subgroups under temperature-humidity interactions. An early warning model based on temperature-humidity indicators successfully predicted HFMD and DV outbreaks, establishing a novel framework for future epidemiological analyses grounded in temperature-humidity evidence. This study provides actionable insights for optimizing region-specific public health interventions and strengthening early risk mitigation strategies.<\/jats:p>","DOI":"10.1371\/journal.pone.0337929","type":"journal-article","created":{"date-parts":[[2025,12,5]],"date-time":"2025-12-05T18:33:16Z","timestamp":1764959596000},"page":"e0337929","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":1,"title":["Temperature-humidity
