The Health Service Executive has said that there have been four more deaths from human swine flu in the past week.
This brings the number of people to 32 who have died from the virus.
There has been a slight decrease in new cases reported - with over 7,700 new cases diagnosed in the last week.
Flu activity remains high and the number of people admitted to hospital also continues to rise.
So far this season, 573 people have been hospitalised, and 52 of these patients remain in intensive care units.
Most of the influenza cases diagnosed involve human swine flu.
The HSE says it is too early to predict whether the peak has been reached and that high levels will probably continue for a few weeks.
Meanwhile, the number of swine flu-related deaths in Northern Ireland since the beginning of flu season in November has reached 21.
Four people, including a 10-month-old baby, have died from the H1N1 virus since Northern Ireland’s Public Health Agency's last briefing a week ago.
The death of a two-year-old child from the Republic of Ireland at a hospital in Northern Ireland at the weekend was not included in today's figures following agreement with the HSE that the child's death from swine flu be registered in the South.
Of the 21 confirmed deaths, 18 patients had an underlying health condition, two did not and one is not yet known.
28 adults suffering from swine flu are receiving critical care treatment at hospitals across Northern Ireland.
At a briefing in Belfast this morning, Dr Carolyn Harper of Northern Ireland's Public Health Agency said that despite four further deaths, overall there is less flu around suggesting the peak of the flu season has passed there.
