The Health Minister has been informed of a second swine flu related death
The Department of Health has confirmed that a baby who died in hospital in Northern Ireland had been diagnosed with swine flu.
However, in a statement, it said the child had a pre-existing heart condition which was the cause of death.
The sex and age of the baby has not been released. The family has asked for their identity to be kept private.
Health Minister Michael McGimpsey said they were respecting their wishes and no further details would be released.
"I understand that there will be a level of public and media interest in this death, but we all must remember that at the centre of this tragic incident is a family who are grieving," said Michael McGimpsey.
Last month, a woman from County Antrim became the first person to die from the virus in Northern Ireland.
Caroline Hoy from Ahoghill had also been suffering from cancer.
In July, soldier Lee Porter (30) who was born in Coleraine, died in a hospital in England from swine flu.
There have now been 217 laboratory confirmed cases in Northern Ireland, although the number of clinically diagnosed cases stands at almost 9,000.
A total of 94 people have been hospitalised.
