Why is Global Health Important?
Global Health affects all of us.
- Travel and Migration
- You can reach any area of the globe within 24 hours, bringing infections.
- Over 500M cross national boundaries each year by plane alone.
- Inadequate Public Health Infrastructure
- Bioterriorism, Zika virus, ebola and other problems highlight challenges in the United States and many other systems to address catastrophic scenarios.
- Urbanization
- Global economy and migration to cities cause overcrowding, water and sanitation problems, pollution, and other health risks.
- Globalization of Trade
- Varied or absent regulations
- Increases risk from pesticides, industrial toxins, and hazardous wastes.
- Lack of strict export safety on foods and products.
- Varied or absent regulations
- Aging and Chronic Diseases
- By 2025, more than 800 million people will be over 65 and two-thirds will be in low-income countries.
- Chronic diseases associated with aging and the costs of treating these will deplete already limited health resources of poor and rich nations alike.
