 Within the host (animal) there are a number of steps that determine if the animal develops disease after being exposed to an infectious agent for that disease.

 Epidemiology studies patterns of disease occurrence. To find the patterns we need to count cases and non-cases. These counts can be used to describe disease occurrence in terms of '''''time, place, and animal'''''. Doing this will help us understand the disease, its impact, and explain how and why the disease occurred. This will help develop control strategies.

+'''''Time'''''
 Describing disease occurrence in '''''time''''' is usually done using epidemic curves. An epidemic curve is a plot of the number of new cases of disease over time.
