epidemiology

With just some simple arithmetic, you can build a basic mathematical model of how a disease might spread. Julia Gog explains how, and there's also some Lego action...
You can explore how we might extend our model but running your own epidemic with our Lucky Dip interactivity. Follow along with Julia as she paves the way to a model that is very similar to the mathematics disease modellers use every day.
In Part 3 Julia refines our model to use one of the most important numbers in disease modelling. And there's a chance for you to explore its meaning using a new interactivity.
In the final Part we explore what other aspects we need to consider to make a model more realistic. There's an interactivity that allows you to party, commute, and visit friends and we find out more about what life as a research is like from Julia.
In this final part, you can meet the researchers themselves and find out about the real research questions that Julia and some of her colleagues are working on!
Find out the basics of the SIR model, the basis most disease modellers use to understand the spread of a disease through a population.

The reproduction ratio, R, is one of the most important numbers in epidemiology. Find out what it means in this very easy introduction.

At the beginning of an epidemic the number of infected people grows exponentially. But why does the number e appear in descriptions of this growth?

To work out how a disease will spread you need to know the time between infections.
How can we use mathematics to model the spread of a disease?
The doubling time of a disease is the time it takes for the number of cases of the disease to double. How do you calculate it?
What is the growth rate and what does it tell us about an epidemic?
