Health officials are investigating an outbreak of Legionnaires’ disease in Carmarthen.
Three people, all with links to Carmarthen, were admitted to hospital as a result of their illness but have since been discharged.
Legionnaires’ disease is contracted by breathing in droplets from contaminated water sources. It cannot be passed from person to person.
Symptoms include breathlessness, chest pain and a dry cough, as well as fever, muscle aches, and sometimes vomiting and diarrhoea.

We are continuing to speak to the three people who have been unwell to gain a better understanding of their movements in the days before they became ill in order to try and identify the source of the disease.
It is important to note that Legionnaires’ disease is very rare and most people who come into contact with the bacteria that cause infection will not become ill. People over the age of 50, particularly men and smokers, are most at risk.
In an unrelated case, precautionary measures have been taken at Llandrindod Wells hospital after legionella bacteria - which can cause Legionnaires' disease - was found during routine tests on the hospital's water supply.
There are no reported cases of anyone being affected at this time, but Powys Teaching Health Board says anyone concerned should contact their GP or NHS Direct.

It’s important to remember that there have been no reported cases of Legionnaires’ disease.
Legionella bacterium has the potential to cause Legionnaires’ disease which begins with flu-like symptoms and can lead to pneumonia and can be life threatening. Not everyone who comes into contact with the bacteria will become ill.
Anyone who is concerned about their health should contact their GP or NHS Direct Wales.
