Legionnaire's disease
Legionnaire's disease

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

How you get Legionnaires' disease

You can catch 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 very rare to catch it at home.

You can catch it from things like:

  • air conditioning systems
  • spa pools and hot tubs
  • showers, taps and toilets

You cannot usually get it from:

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

  • you have severe chest pain

These could be symptoms of Legionnaires' disease.

NHS 111 Wales will tell you what to do. They can arrange a phone call from a nurse or doctor if you need one.

Treatment for Legionnaires' disease

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

Treatment in hospital may include:

  • antibiotics 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.
