This subject is a core subject within the Master of Public Health, the Master of Epidemiology and the Master of Science (Epidemiology). Students should enrol in this subject early in their program of study.

Epidemiology is the discipline of studying the distribution and determinants of disease in populations and is a fundamental science of public health. It plays major roles in the development and evaluation of the policy and practice of public health and health care.

The subject covers measures of disease frequency, measures of association between disease and potential risk factors and measures of the impact of specific risk factors. The common experimental and observational study designs, and systematic reviews, and their relative strengths and weaknesses are discussed. The implications of common types of bias (selection bias, information bias, and confounding) are discussed, as are methods to minimise them. Causal inference is considered within a framework of critical appraisal of epidemiological evidence. The validity and performance of screening and diagnostic tests are considered. Current infectious diseases will also be examined by considering the principles of infectious disease transmission. Surveillance systems and the data produced from these systems will be analysed and examined in the framework of the public health decisions that are made on the basis these data.

At the completion of this subject, students are expected to be able to:

• Calculate and interpret measures of disease frequency, association and impact.
• Recognise confounding and the common forms of bias in epidemiological studies and discuss means to minimise their effects.
• Recognise the roles, strengths, weaknesses and ethical conduct of randomised controlled trials, systematic reviews and the common observational designs.
• Perform a basic critical appraisal of an epidemiological study.
• Calculate and interpret measures of screening and diagnostic test.
• Assess whether associations are likely to be causal or non-causal
• Describe the basic principles in infectious disease transmission and apply these to diseases of global public health concern
• Describe and compare the different types of surveillance systems. Locate and interpret the routine data collected in these systems.
