The Global Public Health concentration brings a multidisciplinary perspective to the understanding of people's health worldwide. Key concerns include health problems specific to certain populations, disparities in access to healthcare within and between countries, health needs in humanitarian emergencies, and global health threats such as pandemics. Significant consideration is given to how political, economic, and cultural contexts affect people's health, what ethical issues arise in regard to healthcare, and how global health initiatives and domestic policies and programs seek to provide solutions.
