Kildare, Laois and Offaly need to "hold firm" in their fight to suppress the spread of Covid-19, acting chief medical officer Dr Ronan Glynn has said.
r Glynn said the latest figures showed that Covid-19 cases were increasing in other counties and that a "united" approach was needed in order to lower the risk of transmission.
"We expected that this week the daily figures we report would rise and fall," he said.
"Nphet is closely monitoring all trends, patterns and changes in the data, including not just case numbers but locations, age groups, and sources of transmission.
"We are asking those in Kildare, Laois and Offaly to hold firm and stay with us in the measures introduced last weekend. As today's figures show, cases are also occurring in several other counties around the country.
"This is still about a united, whole of country approach. The only way we can effectively suppress Covid-19 across Ireland in the long term is if we act together to protect each other.
"Living with Covid-19 has undoubtedly been difficult and this pandemic has adversely impacted on people in many different ways.
"We know that what the public health advice asks you to do can be difficult, but we are asking you to stay the course with it."
Yesterday, the Department of Health reported 92 additional confirmed Covid-19 cases in Ireland, and no further deaths.
There is now a total of 26,929 confirmed cases of Covid-19 in Ireland and 1,774 coronavirus-related deaths.
Of the cases notified, 24 are in Dublin, 24 in Kildare, eight in Limerick, six in Carlow, six in Kilkenny, five in Meath, five in Clare and the remaining 14 cases are in Cork, Donegal, Kerry, Laois, Louth, Monaghan, Offaly, Waterford and Wicklow.
Twelve Covid-19 cases have been identified as community transmission and 43 are confirmed to be associated with outbreaks or are close contacts of a confirmed case.
Forty-three cases are men and 48 are women.
Dr Glynn urged the public to adhere to the public health guidelines in order to "break the chains of transmission."
He said: "Individual actions break the chains of transmission of this virus.
"Avoiding crowded places, limiting your social contacts, working from home where possible, not attending house parties, keeping a two-metre distance, washing your hands and wearing a face covering - all of these safe behaviours matter, and all of them add up to make a significant difference."
