The study was conducted with focus groups and interviews involving 193 medical students and 46 physicians (clinicians) working in hospitals and part time teaching. It seeks to reveal perceptions and tendencies towards an actice response of the health sector. Findings include a scientific view of the climate change, the warming earth, the rising sea and their effects on health and disease. These effects could be direct or indirect via pathogens and intermediate vectors. Five diseases were reported to be most influenced by climate change (malaria, dengue, typhoid, diarrheas and spirochetoses) on resaoning patogenesis pathways. No accurate experimental evidence to prove relationships between climate change and health, but assuming that such relationships exist, the theory of "cold and heat" from "Yang and Yin" as well as dietotherapy are proposed to be used for secondary prevention and treatment of related pathological problems due to climate change.
