Can the risk of Legionnaires Disease be determined by geographical location?
A. No. Legionnaires disease is not specific only to certain areas. Although some areas have reported more cases of LD than other areas, the geographic location is relatively insignificant. Whats more, the number of cases reported from a given area could indicate the level of awareness among physicians and the availability of laboratory testing, as opposed to the level of legionellae in the water supply. Legionella contamination is usually tied to the condition of a buildings mechanical system, which is independent of geographical location.
