One hundred and eleven cases of legionnaires' disease were reported in England and Wales in 1991, a smaller total than in any year since reporting began in the late 1970s. Four cases were hospital acquired and a further nine may have been associated with a hospital stay. Nosocomial legionellosis remains a cause for concern. Fifty-two cases were associated with travel abroad.
