, Exam study material
Exam preparation
The exam will consist of both knowledge and insight questions that are based on the book
of Webber, the lectures and any additional reading material as published on
CANVAS. Questions will be both open questions, and multiple
choice questions which require explanation. A mock exam will be made available.
Exam study material
• Lectures, published on CANVAS;
• Book chapters 1 – 6, and selected diseases (see below and introductory lecture);
• Extra reading material as published on CANVAS and indicated as such
Please note that you don’t have to know everything and all details by heart, just grasp the
main messages with a focus on what is relevant for Containment.
The lectures
All lectures are part of the exam material. Questions will relate to the infectious diseases
and their epidemiology, the control strategies and what are strengths and weaknesses, the
policy framework and relevant and contextual factors that may influence control. Note
that for specific approaches: e.g. cost effectiveness, we may also ask questions about that.
Selected diseases
Below we have provided the list as copied from the introduction lecture. We do not
expect you to know all the details of the selected infectious diseases, but you do need to
know the relevant disease aspects in relation to the containment/control strategies, such
as:
• What is it (virus, bacterium, parasite, worm);
• What does it cause – disease with clinical features such as fatality, morbidity, common
symptoms;
• Diagnosis – only when very important in control, and when it is very easy or just very
difficult;
• Transmission – important routes of transmission between people (e.g. airborne,
waterborne, vector borne, etc);
• Incubation period and period of communicability – only in general terms, and in
relation to control (e.g. infectious when no symptoms? Direct transmission between
people or only through vector? Very long incubation period?);
• Occurrence and distribution – where in the world? Widely spread? Prevalence?
Endemic or epidemic?;
• Prevention and control – understand the most important elements;
