Legionnaires' disease is a lung infection you can get from inhaling droplets of water from things like air conditioning or hot tubs. It's uncommon but it can be very serious.

You can get Legionnaires' disease if you breathe in tiny droplets of water containing bacteria that cause the infection.

It's usually caught in places like hotels, hospitals or offices where the bacteria have got into the water supply. It's less common to catch it at home.

You can get Legionnaires' disease from things like:

• air conditioning systems
• humidifiers
• spa pools and hot tubs
• taps and showers that are not used often

You cannot usually get it from:

• drinking water that contains the bacteria
• other people with the infection
• places like ponds, lakes and rivers

Symptoms of Legionnaires' disease include:

• a cough
• shortness of breath
• chest pain or discomfort, particularly when breathing or coughing
• a high temperature
• flu-like symptoms

Ask for an urgent GP appointment or get help from NHS 111 if:

You may need to go into hospital if you're diagnosed with Legionnaires' disease.

Treatment in hospital may include:

• antibiotics given directly into a vein
• oxygen through a face mask or tubes in your nose
• a machine to help you breathe

When you start to get better you might be able to take antibiotic tablets at home. Antibiotic treatment usually lasts 1 to 3 weeks.

Most people make a full recovery, but it might take a few weeks to feel back to normal.
