In the period August 10-29, 1986, 29 confirmed cases of Legionnaires' disease occurred in Sheboygan, Wisconsin; two cases were fatal. No common source of indoor exposure was identified. Water specimens were obtained from all known cooling tower units in Sheboygan; Legionella pneumophila serogroup 1 was isolated at 1 x 10(6) colony-forming units per liter from a specimen obtained August 27 at plant A. This isolate was identical to the only clinical isolate by monoclonal antibody and isoenzyme subgrouping. Of 29 persons with Legionnaires' disease, 21 lived or worked within one mile (1.6 km) of plant A; seven of the remaining eight visited within one to two miles (1.6 to 3.2 km) of plant A from three to seven days before onset of illness. Attack rates were highest for persons living within 0.5 mile (0.8 km) of plant A. These findings associate a cooling tower with community-acquired Legionnaires' disease and suggest that dissemination of Legionella may occur over longer than previously recognized distances. |
