The omicron variant of Covid-19 has been detected in 4 of the South East counties.
A breakdown of where the strain has been identified is published in today's Irish Independent and includes Carlow, Kilkenny, Waterford and Tipperary.
Meanwhile we're being urged to only meet people we intend spending Christmas Day with this week.
Dr Tony Holohan says the highly transmissible Omicron variant now accounts for two thirds of new Covid cases.
Vaccines
One in every six young adults still aren't fully vaccinated.
NPHET says they either haven't come forward for vaccination, or have received only one dose.
Meanwhile, people who've had Covid now only have to wait three months to get a booster - compared to six months previously.
