ABSTRACT The detection in April 1997 of a case of nosocomial legionellosis in our hospital led to the discovery that both our hot‐ and cold‐water circuits were heavily colonized with Legionella pneumophila. Conventional methods for eradication of the organisms were unsuccessful, so a copper‐silver (Cu‐Ag) ionization system and a continuous chlorination system were installed. Five months later, the number of colonized sites decreased from an initial 58.3% to 16.7%.
