Disease clusters attributed to environmental exposures are observed increasingly more often in France. In principle, all of them should be investigated and the statistical significance of any reported excess verified. If confirmed, both etiological research and a set of general public health measures are necessary. When investigating these clusters, however, it should be borne in mind that they may be due to chance alone. We propose a tool for decision‐makers in public health to help take into account the random component of a cluster.
