説明

<jats:title>Abstract</jats:title><jats:p>An infectious disease typically spreads via contact between infected and susceptible individuals. Since the small‐scale movements and contacts between people are generally not recorded, available data regarding infectious disease are often aggregations in space and time, yielding small‐area counts of the number infected during successive, regular time intervals. In this paper, we develop a spatially descriptive, temporally dynamic hierarchical model to be fitted to such data. Disease counts are viewed as a realization from an underlying multivariate autoregressive process, where the relative risk of infection incorporates the space–time dynamic. We take a Bayesian approach, using Markov chain Monte Carlo to compute posterior estimates of all parameters of interest. We apply the methodology to an influenza epidemic in Scotland during the years 1989–1990. Copyright © 2002 John Wiley & Sons, Ltd.</jats:p>
