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?

What is the generation time of a disease?To work out how a disease will spread you need to know the time between infections.

How can maths fight an epidemic?How can we use mathematics to model the spread of a disease?

The doubling time of a diseaseThe 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?

The growth rate of a diseaseWhat is the growth rate and what does it tell us about an epidemic?

R and herd immunityWhat is herd immunity and what does it have to do with a number called R?

Maths in a minute: AlgorithmsThe word "algorithm" has probably got more usage over the last few years than it has in its entire history. But what exactly is an algorithm?
