The HSE has confirmed that another three residents are showing symptoms of the outbreak which has so far killed six elderly people.
This brings to 14 the number of patients at the nursing home who are suffering from the condition.
Last night a HSE team was still at the home, where patients who are ill have been segregated from other residents.
A Health Information and Quality Authority inspection team left the home yesterday. It has not said when its report will be published.
The authority was called in to the nursing home when a GP notified the HSE about the flu outbreak on April 1st, after five people had died over a short period.
Guidelines given to nursing homes at the beginning of last winter suggest the HSE should have been called in sooner.
Minister of State for the Elderly Kathleen Lynch has said public health officials should have been called to the home before April 1st.
“The lesson to be learned is, where you are dealing with vulnerable people in a private or a public nursing home, keep the Department of Health informed when anything . . . outside the norm occurs so we can help.”
She said notification should be given, not so a penalty can be imposed, “but so we can help and ensure that operators are assisted in the care of very vulnerable people . . . We are not certain whether early intervention would have had any different result.”
