Synopsis

This unit focuses on prevention and control of communicable diseases and non-communicable diseases. Topics include principles of infection, outbreaks, public health control measures such as tobacco smoking, obesity, hypertension and current issues in disease prevention and control. Public health control measures discussed may include surveillance, modelling, immunisation, antimicrobial therapies, infection control, vector control, screening and risk factor management. These topics are illustrated using relevant examples of communicable diseases such as vaccine-preventable diseases (e.g. influenza); vector-borne diseases (e.g., malaria), food-borne diseases (e.g., salmonella) and sexually transmitted infections (e.g. Syphilis). Epidemiological, social, and political perspectives are also discussed.
