Legionella

Legionella is a type of bacteria naturally found in water that can grow in man-made systems such as hot water tanks, showers, taps, and cooling towers. When inhaled as aerosolised droplets, it can cause Legionnaires’ disease, a severe form of pneumonia, or Pontiac fever, a milder flu-like illness. Older people, particularly those with chronic conditions or weakened immunity, are at significantly higher risk of severe illness or death, making Legionella management critical in aged care.

Aged care facilities often have complex plumbing and hot water systems that can create ideal conditions for Legionella to multiply if not properly managed. Effective prevention not only protects residents, staff, and visitors, but also ensures compliance with Australia, New Zealand, and UK health and safety regulations. Legionella management is a key part of broader infection control, supporting a culture of safety, quality care, and organisational resilience.
