Statistical time series models are practical tools in public health surveillance.
Their capacity to forecast future disease incidence values exemplifies their usefulness.
Using these forecasts, one can develop strategies to trigger alerts to public health officials when irregular disease incidence values have occurred.
Clearly, the better the forecasting performance of the model class used in the time series analysis, the more realistic are the alerts triggered.
The time series analysis of disease incidence values has often entailed the Box and Jenkins model class.
However, this class was designed to model real-valued variables whereas disease incidences are integer-valued variables.
A new class of time series models, called integer-valued autoregressive models, has been developed and studied over the past decade.
The objective of this paper is to introduce this new class of models to the application of time series analysis of infectious disease incidence, and to demonstrate its advantages over the class of real-valued Box and Jenkins models.
The paper also presents a bootstrap method developed for the calculation of forecast interval limits.
