Abstract | The authors performed a cross sectional epidemiological survey to investigate the source of a hospital Leginnella outbreak originating in contaminated water. Water temperature and air humidity around possible contamination sources. A dead-end pipe was found to contain LegioneIla pneumophila serogroup 1. All individuals who acquired legionellosis had spent at least 30 min within 2 m of the contamination source. Among staff, 41 of 71 were exposed, and 31 of these fell ill. All 7 palients exposed to the contaminated water acquired legionellosis. None of the 94 bed-ridden patients from the same units developed the disease. An aerosol wilh = 60% relative air humidity was formed near the suspect water faucets, but the humidity fell rapidly farther from the water source, suggesting desiccation decreased the risk of infection. The closest healthy personnel and patients acquired legionellosis, suggesting that risk was less related to compromised patients than to exposure. | |
