RTE News reports the Health Service Executive has confirmed that a child has died from influenza at a Dublin hospital in the last week.
While they did not identify the child, the HSE said they were not from Dublin.
The virus involved is the H1N1 virus (Swine flu) which has been circulating in Europe as part of annual flu.
The HSE has said sadly each year a small number of children die from influenza.
It says there is no reason for alarm.
Protection against the virus, now part of annual seasonal influenza, is available under the annual flu vaccine.
Though late in the season, all at risk people who have not yet received a vaccination are advised to do so.
The strain in this case is the human swine flu virus which has been in circulation since the 2009 outbreak.
Influenza cases in Ireland continue to increase, according to the HSE’s Health Protection Surveillance Centre.
Nine flu deaths have been reported so far this season.
The HSE says that no excess cause death rates have been reported here so far this winter season.
