And crucially, just how unlikely is this clustering of cases? (emfs.info)
Similarly, it is only natural to draw an area on the map that encloses the cases we have observed, and to say that that line is the extent of the cluster. (emfs.info)
Many groupings of cases that strike the people who first notice them as a cluster don't stand up to rigorous scrutiny - either they depend on definitions, of the cases or the area, that have been chosen to fit the evidence, or they turn out statistically not to be sufficiently unusual on a national scale, however remarkable they may look in isolation.

Investigate the connections made by literature between individuals, across boundaries of time and space. (uaeu.ac.ae)

Organizationally, each agency should have an internal management system to assure prompt attention to reports of clusters. (cdc.gov)
This item should command attention from people entering the space, and send a clear and inviting signal, drawing the viewer in. (artsyshark.com)
A related tactic is to pay attention to the negative space between works on display. (artsyshark.com)
