Legionella is a potentially fatal illness caused by bacterial growth in water. The right conditions can create the perfect storm for a Legionella outbreak in a hospital. The bacteria can be found anywhere from hot water storage tanks to showers and birthing pools.

Hospitals are at risk of Legionella outbreaks as many collect and store hot water as they need to have a reliable and instant supply.

Patients rely on hospitals to provide a constant supply of hot, clean water. Those in hospitals are often more vulnerable and more susceptible to harm, so it's essential that high levels of hygiene are maintained for patient safety.
