Cluster detection depends on lay residents noticing small run counts.

Evidence

Anne thought it strange that three cases of leukemia should occur in the same neighborhood, within a few blocks of each other. She wondered if it was coincidence, or if a virus of some sort was circulating. Dr. Truman, she remembered, had mentioned that some cancer researchers suspected a virus might cause childhood leukemia. Although she knew that was an unproven hypothesis, she and Carol Gray spent hours speculating about it. — , Harr Jonathan - A Civil Action, 54
