EPIDEMIOLOGY OF INFECTIOUS DISEASES - 2024/5

Module Overview

Microbes can be categorised and studied according to a number of characteristics such as their physiology; pathogenicity, and cellular interaction with hosts. This module builds on those themes already covered on the bioscience programmes in dealing with the spread of microbes through populations, and features of host and vector populations that influence this spread.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

• Understanding of the cycle of infection and factors which influence the spread of infectious disease, and use this information to analyse the control points for selected infectious diseases


• Ability to evaluate prevention and control strategies such as vaccines and antimicrobials, together with use of screening tools


• Ability to discuss epidemiological methods for detection, analysis and control of outbreaks of infection and epidemics, and analyse simple epidemiological data


• Understanding of the methods available for typing microorganisms and their application to epidemiological investigation


• Consideration of geopolitical and socio-economic factors in influencing the prevalence of infectious diseases

 

  Thus, the summative assessment for this module consists of:

# Case study: online test; open-book; deadline: Week 34 or 35 (dependent on where Easter break falls) (50%) – this assessment addresses learning outcomes 1-5

 

# Online exam: A one-hour exam, with MCQ / EMQ, and short-answer questions (50%) – this assessment addresses learning outcomes 1-5

 

Formative assessment

Formative quizzes will be provided as part of the computer workshop in the form of exercises to work thorough will immediately feedback into the preparation for the case study coursework. Formative online tests are available as preparation for the exam, with immediate feedback.

Feedback

Individual feedback for the coursework assignment will be provided, together with a broader discussion of the assessment as part of a tutorial at the end of the module

Module aims

• Enable students to gain a critical understanding of the principles underlying the spread of infectious disease
• Develop an understanding of the science behind treatment and prevention strategies such as vaccination and antimicrobial chemotherapy
• Develop the ability to apply methods for studying the spread of disease through the use of examples and simulations
• Critically evaluate select outbreaks of disease through detailed case studies
  
• Consider geopolitical and socio-economic factors that influence prevalence of infectious disease
  
• 
  

Learning outcomes

Methods of Teaching / Learning

  The learning and teaching strategy is designed to:

Introduce fundamental principles of epidemiology and control of infectious diseases, and develop an understanding of     these principles using data from genuine outbreaks.

The learning and teaching methods include:

• Lectures


• Tutorials and workshops; including data analysis; outbreak simulation, discussion in small sized classes.

 

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

Other information

Resourcefulness & resilience: Part of the coursework includes activities that require self-directed learning from students, seeking out information from online resources and analysis of past microbial pathogens outbreaks. Students are given some direction for these components but need to engage in self-directed learning to complete these successfully.

Global & cultural capabilities: This module includes many case studies and coursework exercises that foster discussion of emerging diseases, and outbreaks, from a global perspective. This includes, for example, discussion of cholera outbreaks in war-torn and resource-limited countries, and health inequalities highlighted by the Covid-19 pandemic.

Sustainability: This module deals with antimicrobial resistance resulting from overuse in humans and other animals. Control of resistance through sustainable use of these drugs is covered. The link between environmental destruction and emerging infectious disease is discussed in lectures on this module

Digital capabilities: Data analysis skills are used to analysis outbreak data, consistent with those methods that would be used for publishing epidemiological research. 

Employability: Outbreak investigation workshops are based on genuine epidemics and involve qualitative and quantitative approaches that are used by professional epidemiologists for understanding real-world outbreaks.
