The learning objectives for this lecture are straightforward. You should be able to compare and contrast the concepts of health, illness and disease, and analyze each of these concepts from a number of different dimensions.

You must recognize and describe epidemiological transitions.

Finally, you need to be able to analyse factors that might link environmental and medical outcomes.

This is a lot of “stuff” to cover. It isn’t possible to address it all in a one hour lecture. These notes therefore supplement, and provide a background to what will be presented in the lecture. You are strongly encouraged to read and think about these notes in advance of the lecture itself.
