Abstract
Climate change poses the greatest public health threat, disproportionately impacting communities in Low‑ and Middle‑Income Countries (LMICs) where fragile health systems increase vulnerability. Despite this, clinical practice often overlooks climate‑related health risks. Current approaches focus on single disciplines or settings, limiting broader integration. Incorporating a One Health approach—recognizing the interconnection of human, animal, environmental, and plant health—into routine clinical encounters offers a pathway to strengthen climate‑health awareness. This manuscript presents practical guidance for integrating climate and health histories, with a focus on heat exposure, and emphasizes the role of physicians, other health providers and three categories of Community Health Workers (CHWs) across the care continuum. A case study illustrates how targeted climate and environmental inquiries during history‑taking can advance diagnosis and patient education. Embedding One Health in clinical care bridges existing gaps, enhances early detection of climate‑related illness, and promotes culturally sensitive, holistic health interventions in vulnerable communities.
