Naas General Hospital has confirmed an outbreak of Covid-19 on one ward, which was notified yesterday.
It said the ward is closed to new admissions and the patients continue with their care.
The hospital said that swab tests of patients came back negative this evening. Testing and contact tracing of staff is under way.
It said that staff identified as close contacts are self-isolating.
Under the medical definitions for Covid-19, an outbreak can involve one confirmed case and a cluster normally means two or more cases.
The HSE's latest data shows that as of last night, the hospital was treating eight suspected cases.
On Sunday night, it was treating six suspected cases.
Naas says it has no confirmed cases.
Meath creche outbreak
The CEO of Daoine Oga Community Childcare Centre in Navan, Co Meath has said she has noticed a delay in Covid-19 test results since her staff were first tested around the bank holiday weekend.
The centre has shut its doors for a week, after two staff members and three children tested positive for the virus so far.
Speaking on RTÉ's Drivetime, Marie Daly said the turnaround on testing has got slower.
She said at the beginning they were getting test results back within 28-30 hours, it has since taken two days and she said it is being pushed out to three days.
The first staff member at the Daoine Oga creche who was tested on bank holiday Monday 3 August, got their positive test result late in the afternoon the following day.
Marie Daly said she was advised by public health officials to close down the creche because there was no link between the two staff who tested positive and so it was deemed to have been community transmission.
