Welcome to the first module of this global health course. In the first lesson we will introduce you to the overall concepts and definitions of global health and examine the question "What are the biggest global health challenges?". You'll get to hear some answers from fellow learners from around the world, and also have an opportunity to join the conversation here in the course discussion forums. We also have an interview with Professor Susan Whyte about the impact of health policy on a population's health. The second lesson deals with the central tools needed to measure global health burden. Together these two lessons will form the basis on which all the other topical modules are built. Enjoy!

The second module of this course is focussed on infectious diseases. Lesson 3 will introduce you to the concept of infectious diseases and their relation to poverty and development, and lesson 4 will go through three prominent examples of infectious diseases that are still unfinished agendas in large parts of the world.

In the third module we'll have a closer look at non-communicable diseases, in short NCDs, and examine the forces that are behind the global epidemic rise of NCDs such as diabetes. The module also includes a lesson about mental health and injuries - two major global health challenges that are often ignored when dealing with NCDs.

This fourth module deals with maternal and child health. The first focus will be on the important, and at times controversial, topic of sexual and reproductive health and rights, often shortened to SRHR. This is followed by a short lesson focussed on child health.

In the fifth module we are looking at some great global crises that profoundly impact the health of populations, namely environment, climate change, and migration. We will examine the health acpect of these mega trends - how are they influencing and challenging policy, health systems, and the health of individuals in both low and high income countries?

Access to nutrituous food and clean water are fundamental to health and wellbeing. In the sixth module we are focussing on the role of nutrition and water, with some extra attention to the important role of sanitation and hygiene and their relation to human development.
