This article presents a review of two popular methods for temporal surveillance and proposes a general framework for spatial and spatiotemporal surveillance based on likelihood ratio statistics. It is shown that the cumulative sum and Shiryayev-Roberts statistics are special cases under such a general framework. The efficiencies of some surveillance methods are compared for the detection of clusters of high incidence rates in spatial and spatiotemporal applications using both Monte Carlo simulations and a real example.
