A hospital has re-opened to new admissions after part of its water system was found to contain legionella, which can cause Legionnaires’ disease.
The bug was discovered at Llandrindod Wells Hospital in Powys around a fortnight ago following concerns over water quality.
Health officials said they would continue to monitor the water supply.
Bottled water was used for washing until the system was flushed through, said Powys teaching Health Board.
The board said the hospital returned to normal and opened to new admissions on Friday.
