HAR6048: Epidemiology (online)


As one of the core disciplines of Public Health, epidemiology is concerned with the methods of studying health related states and events to control health problems. The module covers epidemiological measures, main study designs, screening and surveillance. The primary objective is to introduce students to the principles, tools and applications of epidemiology and to help develop their practical skills through a range of activities.


This module aims to equip the student with an understanding of the epidemiological principles, methods and their applications.

Learning Outcomes

By the end of the unit, a candidate will be able to:

  • Describe, apply and interpret epidemiological measures
  • Explain the use, advantages and disadvantages of the different study designs
  • Identify and assess the implications of bias, confounding and effect modification in epidemiological studies
  • Summarise the uses, strengths and weaknesses of routine data, screening and epidemiological surveillance

Teaching Methods

The teaching methods include guided independent study and facilitated discussions with constructive feedback. The module workbook will provide step-by-step guidance for self-study, questions to provoke critical thinking and examples to allow students to consolidate their learning.

Students are also expected to complete a number of preparation and revision tasks throughout the module, and to engage fully with the self-directed study required.
