The HSE has launched a probe into a suspected case of Legionnaires' disease at Galway hospital Merlin Park.
It is suspected the patient contracted the disease by using the shower.
According to Galway Bay FM, there are currently no concerns for patients safety, and that all patients who attended Merlin Park within a three-week period prior to the case in June have been identified.
None have displayed symptoms of the disease thus far.
Legionnaires disease is a severe form of pneumonia which infects roughly ten people a year in Ireland and is most commonly contracted abroad.
A review was carried out of water systems at Merlin Park and additional measures have been put in place.
