Parents are being urged to look out for symptoms of hepatitis in their children.
The HSE confirmed this morning that one child has died from a probable case of hepatitis.
Another child has received a liver transplant.
A total of 6 cases have been detected here in the past 10 weeks, involving children aged between one and 12 years old.
Parents are being told to contact their GP immediately if their child shows any symptoms, including dark urine, pale, grey-coloured poo or any signs of jaundice, such as yellowing of the eyes or skin.
