2.1.4 What is rabies incidence?

Rabies incidence is the number of new rabies cases identified within a specified time period divided by the size of the population (humans, animals) initially at risk. Expressed in simplified terms, rabies incidence answers ‘How many individuals (people, animals) newly acquire rabies in a year?’. Typically this is applied to people, such as, for example, an incidence of 2.4 human rabies cases per 100,000 per year. In contrast, prevalence includes both new and existing cases over time, for example the number of foxes reported as rabid in Europe during 2014, without an accurate estimate of the actual population at risk.
