This unit aims to introduce learners to the key terminology and methods used by epidemiologists. Learners will learn about basic statistics and understand the importance of data collection and interpretation of data for public health. An understanding of epidemiology and statistics is very important for those who work or aspire to work in public health.

This unit aims to introduce learners to a broad range of determinants of health and to take an in-depth look at three key topics: air pollution, nutrition, and water, sanitation and hygiene (WASH). These form the foundation for much public health work in practice. Without the fundamentals of clean air, water and nutrition communities are at high risk of ill health.

This unit aims to introduce learners to the key terms, concepts and themes in public health for learners who are working, or intend to work, in public health. The learners may be aiming for roles working directly with people in their community, or as public health managers or policy makers. It will encourage reflection, comparison and analysis as learners begin to consider the impact of politics, development, the economy, environment, society and culture on the health of individuals and populations in their own locality, nationally and globally. 

This unit aims to introduce learners to the fundamentals of psychology, communication skills, sociology and social policy as a basis for further study in later public health management units. This unit is especially important in introducing the learners to the ethical foundations of society and is crucial for those who work or aspire to work in public health.

This unit aims to provide learners with basic grounding in areas of science which are especially relevant to public health. It will help to ensure that all learners have an understanding of how our bodies work (anatomy, physiology and biochemistry) and how they may become infected (microbiology and parasitology). By studying environmental science, learners will appreciate the importance of the environment to human health.
