Module content and teaching

Principal aims

This module builds on the introductory first year virology component of BS127 Agents of Infectious Disease and is complementary to BS270 Virology. It deals with an important aspect of virology, virus infection at the ‘whole organism’ level, elements of which are developed further in the final year for those continuing with Virology or Microbiology and Virology degrees.

Principal learning outcomes

The module is intended to give you an understanding of the wide variety of interactions which take place between animal viruses and their mammalian hosts. You should learn to distinguish between infection and disease, to appreciate how the outcome of an infection is controlled both by properties encoded by the virus and by the host's (largely immune) responses, and to relate these principles in detail to some specific virus-host interactions. You should also gain an appreciation of the concepts of virulence and attenuation, the variety of processes by which viruses cause disease, and how host responses can drive virus evolution.
