The Government and the National Public Health Emergency Team expect to issue updated advice today to those living in Kildare, Laois and Offaly.
Acting Chief Medical Officer Dr Ronan Glynn has advised people living in those counties to pay particular attention to any new symptoms after a huge increase in Covid-19 cases linked to outbreaks.
Dr Glynn said there had been 226 cases of Covid-19 in the last 14 days in three counties, which account for almost half of all cases in Ireland during that period.
NPHET had also been notified of another 60 cases in those counties, which are due to be reported in this evening's figures. He said GPs in those counties had been written to and contact tracing was under way.
