A FOURTH child is being treated for an infection which may be linked to contaminated water at Glasgow's children's hospital.

Tests on the water supply at the Royal Hospital for Children (RHC) have now been extended to four wards after traces of a bacteria were found  which can pose a risk to seriously ill children, including those undergoing treatment for cancer.

NHS Greater Glasgow and Clyde said "robust infection control measures" were in place to protect patients.

Scottish Water and Health Protection Scotland are carrying out the tests.

A health board spokesman said: "Three children continue to receive treatments for infections that may be linked to bacteria found in the water supply.

"Tests are ongoing to confirm if they are indeed linked.

"A fourth patient has shown symptoms and has been readmitted to the RHC.

"There are no reports of any patients being infected by bacteria from water in the adult wards.

"A series of infection control measures were introduced to the affected RHC wards at the weekend and water filters are set to be installed.

"As a result, it is hoped that the full water supply will return to normal within 48 hours after appropriate testing has been carried out and it is anticipated this will be mirrored at the QEUH.

"We would like to thank the patients and families in the wards affected in the RHC for their continuing patience and support while the testing was carried out and fitting of filters is being undertaken."
