The acting Chief Medical Officer is warning that Covid-19 is spreading 'disproportionately' among younger people.
It's after new figures from the Health Protection Surveillance Centre show 40 percent of cases in the last two months have been in people aged between 15 and 34.
Dr Ronan Glynn said the proportion of cases in younger people is not surprising, as they're more likely to be moving about in the community - going to school, college or work, and keeping our economy and key services going.
He acknowledged that for teenagers, and people in the 20's and 30's, what's being asked of them is extraordinary.
Dr Glynn says the vast majority of young people have done the right thing, have heeded public health and kept themselves and their families safe.
Another 334 cases of coronavirus were reported across the country yesterday - half of the cases were in Dublin while in this region, there were 10 more confirmed cases in Co Galway and 6 in both Mayo and Roscommon.
