Legionnaires' disease
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.
How you get Legionnaires' disease
You can get Legionnaires' disease if you breathe in tiny droplets of water containing bacteria that causes 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

Other ways to get help
A GP may be able to help you.
Ask your GP surgery for an urgent appointment.
Tell the GP where you have been in the past 10 days, such as if you stayed in a hotel, spa or hospital.
Treatment for Legionnaires' disease
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.
