Influenza is a disease that strikes in two forms. Seasonal influenza returns each winter, killing up to half a million people in bad years and causing much misery. Pandemic influenza, by contrast, is rare - having occurred only a handful of times in the last century - and far worse than seasonal flu, often killing many millions across the world. The worst pandemic of all, the “Spanish Flu” of 1918, killed over twice as many people as the First World War - some estimates are even higher.
Since 1918, our understanding of influenza virus has come a long way. We can now trace how the pandemics of the last hundred years originated in bird flu and swine flu, and we can model the evolution of the virus from year to year, aiding vaccine design. We also have some anti-viral drugs that can be used in emergencies, and we understand more about how flu is transmitted and possible ways to prevent its spread. In this free online course, we will cover everything from the history of influenza to modern laboratory diagnostics and vaccination. You’ll learn about the annual cycle that brings seasonal flu to our shores every winter, and also how avian and pig flu can contribute to the emergence of new pandemic strains of flu.
We’ll also look at the structure of the virus in more detail, seeing how the study of influenza is now carried out at the molecular level. As well as mini-lectures, there will be laboratory demonstrations, interviews with experts in a variety of relevant fields, and discussion sessions, where you’ll be invited to contribute your own experiences and opinions to the subject of flu, and how we should treat and prevent it.
What topics will you cover?
- Pandemics and seasonal flu
- The basic biology of flu viruses
- Bird flu and how new flu subtypes arise
- How flu spreads and how we can help prevent it
- The body’s response to flu
- Immunisation – the annual flu jab
- Treatment of flu
- Diagnosis of flu
What will you achieve?
- Describe the fundamental virology of Influenza, including its life cycle and molecular structure.
- Explain how influenza evolves and spreads.
- Classify previous influenza pandemics by subtype.
- Describe the difference between the seasonal flu and a pandemic flu.
- Describe how various tools and techniques can be used for diagnostic purposes.
- Contribute in an informed way to current debates around influenza vaccination and prevention.
