Infectious disease affects all our lives to varying degrees, often making front-page news: “New resistant strain of TB”, “Will bird flu cross over to humans?”, “Hospital infections reach epidemic proportions”, etc. This module approaches infectious disease from several perspectives – exploring the underlying biology, epidemiology, ecology and evolution of pathogens in relation to the extraordinary immune defences of their human hosts. You’ll learn how infections are diagnosed, how to study changes in the incidence of diseases, and investigate strategies for treatment and control. You’ll also explore a disease or disease-related topic in detail.
What you will study
Why have diseases such as AIDS spread so rapidly through large areas of the world? Why are some populations so badly affected? How have diseases such as smallpox and polio been controlled? What are the reasons for the emergence of new infectious diseases?
Infectious disease and public health is an exciting module that shows how the causes and control of diseases can be understood only by reference to a range of biological information in the appropriate social context. It aims to:
present a multidisciplinary approach to the study of infectious disease
illustrate this approach through case studies of a range of infectious diseases
develop appropriate skills in reading and abstracting the literature and communicating the module themes coherently and from a multidisciplinary perspective.
By the end of the module, you will be able to:
demonstrate a broad understanding of the range of infectious diseases and their causative agents
demonstrate a broad understanding of the range of techniques used to diagnose infections
describe biological interactions between hosts and pathogens during an infection, and their evolution over time
give examples of the influence of social organisation, culture and economic development on the distribution of infectious disease
demonstrate the ability to interpret basic epidemiological data on infectious disease outbreaks
discuss strategies to prevent or reduce the impact of infectious diseases, commenting on their strengths and limitations
use a variety of methods, including electronic search tools, to access both primary and secondary scientific literature and abstract relevant information for a stated purpose
research and produce an extended piece of written work summarising historical and contemporary aspects of a chosen infectious disease (or diseases), including issues of treatment and control.
Entry requirements
There are no formal entry requirements for this module.
At The Open University, we believe education should be open to all, so we provide high-quality university education to anyone who wishes to realise their ambitions and fulfil their potential.

Teaching and assessment
Support from your tutor
You’ll get help and support from an assigned tutor throughout your module.
They’ll help by:
marking your assignments and offering detailed feedback to help you improve
providing individual guidance, whether that’s for general study skills or specific module content
guiding you to additional learning resources
facilitating online discussions between your fellow students in the dedicated forums.
Online tutorials run throughout the module. While they’re not compulsory, we strongly encourage you to participate. Where possible, we’ll make recordings available.
Assessment
Course work includes:
4 Tutor-marked assignments (TMAs)
2 Interactive computer-marked assignments (iCMAs)
Examination
We regularly review the assessments in our modules, so we may update the examination method used for this module to an in-person exam or an online invigilated exam. When we are making such a change, we will make it clear on this page. If we need to make a change after you have registered, we will notify you as soon as possible. If you have additional requirements, we will support you to complete your assessments.
Laboratory schools
The School of Life, Health and Chemical Sciences offers optional laboratory schools in Milton Keynes at an additional cost. Laboratory schools are not part of this module but may be of interest if you wish to gain relevant hands-on laboratory experience.
Further information and instructions for booking are on the SS032 website.
What's included
You’ll have access to a module website, which includes:
a week-by-week study planner
course-specific module materials
audio and video content
assessment details and submission section
online tutorial access
access to student forums.
Additionally, the website includes:
introduction and guide
case studies
digital microscope
activities
glossary.
You will need
a device to take digital images of your work (e.g. a phone/digital camera or scanner).
Computing requirements
Primary device – A desktop or laptop computer with at least 8 GB of RAM and a quad-core processor (2.4 GHz minimum speed). It’s possible to access some materials on a mobile phone, tablet or Chromebook; however, they will not be suitable as your primary device.
Peripheral device – Headphones/earphones with a built-in microphone for online tutorials.
Operating systems – Windows 11 or the latest supported macOS.
Internet access – Broadband or mobile connection.
Browser – Google Chrome and Microsoft Edge are recommended; Mozilla Firefox and Safari may be suitable.
Our OU Study app operates on supported versions of Android and iOS.
Software – Any additional software will be provided or is generally available for free.
If you have a disability
The OU strives to make all aspects of study accessible to everyone, and this Accessibility Statement outlines what studying SK320 involves. You should use this information to inform your study preparations and any discussions with us about how we can meet your needs.
To find out more about what kind of support and adjustments might be available, contact us or visit our Disability support website.
Future availability
Infectious disease and public health (SK320) starts once a year – in October.
It will next start in October 2027.
We expect it to start for the last time in October 2027.
