Legionella

摘要

Residents in care homes may be particularly susceptible to legionella, which is spread by inhalation of water droplets and/or aerosols, especially where water has not been controlled at the correct temperatures and/or has been allowed to stagnate. Legionella controls include the following:rn1. ensuring hot water supplies are stored at above 60℃ and circulated/supplied at 50℃ (except where thermostatically controlled at patient outlets)rn2. ensuring cold water supplies are below 20℃rn3. ensuring low usage outlets, eg. little used showers, sinks etc are flushed regularly.
