Ministers are meeting this morning to discuss growing concerns about the Delta strain of Covid-19.
The strain, first detected in India, accounted for 20% of new covid cases last week.
Chief Medical Officer Dr Tony Holohan says there's been a 'concerning increase' in cases of the strain here.
Today’s data show a concerning increase in transmission of the Delta variant in Ireland.
We estimate that Delta accounts for up to 20% of cases reported in the last week.
We have also seen a number of outbreaks associated with this variant reported in the last week.
