Legionnaires’ disease is a serious form of pneumonia caused by inhaling water droplets containing Legionella bacteria.

These bacteria thrive in warm, stagnant water environments – commonly found in cooling towers, hot tubs, plumbing systems and decorative fountains.

Though rare, outbreaks can be severe and often occur in places like hotels, hospitals and office buildings where large water systems are in use.

Symptoms to watch for

The disease typically starts with flu-like symptoms that intensify over time.

Common indicators include:

• High fever and chills
• Cough, often dry or mildly productive
• Muscle aches and headaches
• Shortness of breath
• Fatigue, and sometimes gastrointestinal issues like nausea or diarrhoea.

Legionnaires’ disease can be life-threatening, especially for older adults, smokers or individuals with weakened immune systems.

Early diagnosis and treatment with antibiotics are crucial for recovery.

Prevention through water management

The key to preventing Legionnaires’ disease lies in proper water system maintenance.

Proactive steps include:

1. Regular cleaning and disinfecting of cooling towers and water tanks
2. Maintaining appropriate water temperatures (hot water above 60°C, cold below 20°C)
3. Preventing stagnation by flushing infrequently used taps and showers
4. Monitoring and controlling biofilm and scale buildup
5. Conducting routine water testing for Legionella presence.

Effective water management isn't just about compliance – it’s about protecting public health.

With diligence and proper procedures, organisations can dramatically reduce the risk of outbreaks and ensure safe water for everyone.

Clean water doesn’t just hydrate – it safeguards lives.
