Often, the number of case-patients that can be enrolled in a study is limited by the size of the outbreak. This association was confirmed in the laboratory, where the outbreak subtype of the Legionnaires’ disease bacillus was isolated from the water in the mist machine’s reservoir. Official letters are letters written to various public or civil servants who generally head their respective departments, sections, branches or zones. In theory, a propagated epidemic — one spread from person-to-person with increasing numbers of cases in each generation — should have a series of progressively taller peaks one incubation period apart, but in reality few produce this classic pattern.
