The unit uses an ecological approach to examine the relationship between human health and their environment. Various factors in the physical, chemical, and biological environment are studied from an epidemiological perspective. Case studies introduce students to ways of assessing environmental hazards, and control measures are discussed. Current environmental health issues such as world health, air pollution, and climate change are considered.


On completion of this unit students will be able to:

  1. Identify the major environmental factors that influence human health;

  1. Demonstrate a basic level of understanding of the mechanisms involved in the spread of diseases within human populations;

  1. Demonstrate an awareness of the factors involved in risk assessment and risk communication;

  1. Demonstrate an understanding of the epidemiology of infectious diseases and the use of immunisation to control the spread of infections in populations;
