Four children under three remained critically ill in a Belfast hospital last night suffering from meningococcal septicaemia, the most serious form of meningitis.
The child who died in hospital from the severe strain of the illness at the weekend was buried yesterday in Lurgan, Co Armagh.
Another child, who had been in intensive care in the Royal Belfast Hospital for Sick Children, was transferred to a ward bed on Sunday night and was last night "seriously ill but stable".
A hospital spokesman said there was no change in the condition of the four children still in intensive care.
Details of where the children were from were not released, but the spokesman confirmed that the cases were not related and the children came from different parts of the North.
Meanwhile Orla Scullion, the 17-month-old girl who died on Saturday, was buried yesterday. Her parents, Mr Michael Keegan and Ms Tracey Scullion, have criticised the delay in diagnosing and treating their daughter's illness at Craigavon Area Hospital in Co Armagh.
Mr Keegan said he knew the doctors had done their best but he was angry that swift treatment had not been given to his daughter. The child was discharged by the hospital after an initial examination but was brought back by her parents and readmitted when she deteriorated at home.
A spokeswoman for the Craigavon hospital said the child had been assessed on her arrival but there were no signs of meningitis.
"It was only when she was readmitted that the signs were there. This particular strain strikes within hours."
Typical symptoms of meningococcal septicaemia are fast breathing, cold hands and feet and a rash which maintains its colour and appearance when pressed with a glass.
