The majority of outbreaks of Covid-19 last week were in households.
Latest data from the Health Protection Surveillance Centre shows outbreaks in private homes accounted for 56% of the 404 new clusters in the week up to last Saturday.
82 cases of Covid-19 were detected within the Traveller Community in the past week.
Figures also show during the same period there were 24 new clusters in schools, 16 in childcare settings and 19 in workplaces - including 2 in meat plants.
The figures show outbreaks in nursing homes and hospitals have reduced.
Despite the increasing number of outbreaks in schools, the Government is working hard to ensure all secondary students return to school after Easter, according to the Minister for Finance.
Minister Paschal Donohoe says he's aware of the impact of the lockdown on the wellbeing of young people and their families, and what it would mean for young students to get back to "some kind of normal life".
