Essentials of Global Health is a comprehensive introduction to global health. It is meant to introduce you to this topic in well-structured, clear and easy to understand ways. Much of the course will focus on five questions: What do people get sick, disabled and die from; Why do they suffer from these conditions? Which people are most affected? Why should we care about such concerns? What can be done to address key health issues, hopefully at least cost, as fast as possible, and in sustainable ways? The course will be global in coverage but with a focus on low- and middle-income countries, the health of the poor, and health disparities. Particular attention will be paid throughout the course to health systems issues, the linkages between health and development, and health matters related to global interdependence. The course will cover key concepts and frameworks but be practical in orientation.
