The potential of acquiring Legionnaires` disease in the home environment was studied using a case-control design with 146 cases of Legionnaires` disease and 275 matched controls living in two counties in Ohio. By multivariate analysis, cases were more likely than controls to have Legionellae cultured from water sources in the home, to have non-municipal water supplied to their home, and to have had recent plumbing work on their home. Franklin county residents with underlying health conditions had strongest associations with domestic risk of acquiring Legionnaires` disease presence of Legionellae in home (p<0.001), non-municipal water supply (p=0.031), and recent plumbing work (p=0.058). Use of electric home hot water heaters was more common in case homes, but was not a significant risk factor in multivariate analysis, because use of electric tanks was strongly associated with non-municipal water source (p=0.01). The authors feel that a portion of community acquired Legionnaires` disease is acquired in the home and that interventional studies which address means to decrease the risk of domestic acquisition of Legionnaires` disease need to be performed.
