One hundred and twenty-nine cases of legionnaires' disease were reported in England and Wales in 1993. Twenty-two of the cases died. Sixty-six cases (51%) were associated with travel (in the United Kingdom or abroad), six were associated with a stay in hospital, and the remaining 57 were thought to have acquired infection in the community. Two community and two hospital outbreaks were recognised in England and Wales and four outbreaks were detected in travellers from the United Kingdom to Spain, Greece, and the United States. One hundred and six cases (82%) were not known to have been associated with outbreaks, and 51 (40%) of these were not associated with travel or hospitals.
