The HSE is reassuring parents following a suspected meningitis outbreak in Navan, Co Meath.
Two cases were reported last Thursday when two children were admitted to hospital.
A six-year-old girl died and another girl, aged 12, remains seriously ill in hospital.
Support and advice are being provided to parents and teachers in the community and health officials say they're in control of the situation.
Dr Paul Kavanagh is the Director of Public Health Medicine for the HSE in the North East, and says, while meningitis is now a fairly rare disease, people should still be vigilant.
"The sort of this that people should watch out for are a high temperature, a headache, and aches and pains generally, neck stiffness, nausea and vomiting, dislike or intense awareness of bright lights, drowsiness, and fits," he said.
