- •Copper-Silver water ionization disinfection systems can be overcome resulting in nosocomial Legionella outbreaks.
- •Routine monitoring and enhanced monitoring of potable water systems after structural disruptions should be encouraged.
- •In hospital showering activity is identified as a statistically significant risk factor for contracting Legionella during an outbreak.
- •Showering restriction and point of use water filters can help mitigate outbreaks related to potable water.
- •Multidisciplinary collaboration is encouraged to anticipate and assess for vulnerabilities to Legionella outbreaks.
