1.6 What is disease incidence?

Incidence is a measure of the risk caused by a disease as defined by the number of new disease cases within a specified time period divided by the size of the population initially at risk. Expressed in simplified terms, incidence answers: ‘How many individuals (people, animals, etc.) per hundred thousand in the population newly acquire a specific disease in a year?’. In rabies, this is often most relevant in human populations, based upon available public health data.
