AMU How Does Economics Apply to Healthcare Institution Discussion

I’m working on a health & medical discussion question and need an explanation and answer to help me learn.

• How does economics apply to health care? In your own words how do you define health? Conduct a search for the term health from a public health source and choose the one that you think is the best. Provide the reference for this definition and elaborate on why you think this is the best definition.
• Explain how an increase in income would affect the level of health in a relatively affluent country like the United States compared to a relatively poor country like Haiti. Be specific regarding the various factors that influence health and how they may differ in these countries.
