A sabbatical officer member of UCD Students' Union has a confirmed case of swine flu.
In a statement issued tonight the Union said it is believed that a member of the team contracted the virus at the Union of Students in Ireland annual training week, held in Waterford Institute of Technology from 13-17 July.
The man called his doctor to his house in Dublin when he returned from Waterford after displaying flu symptoms.
He was then sent to St James's Hospital, where doctors confirmed today that it has influenza H(1N1).
He has been advised to stay at home for the next few days to recover. The remaining four sabbatical officers have not displayed symptoms of flu.
The officer has not been on the Belfield campus since contracting the virus.
UCD Students' Union is liaising with the university's safety office to ensure that the potential spread of the virus is contained.
As the affected officer has not been on campus since USI training, the chances of spreading are negligible, the Union said in the statement.
Earlier today, the Department of Health released the latest figure of confirmed cases of swine flu here.
It said that there were 164 confirmed cases.
11 new cases have been confirmed since the last department update.
The number of cases of person-to-person transmission is 17.
A priest in Waterford has asked parishoners not to shake hands during mass to stop the spread of swine flu.
Fr Martin Crowe at St Saviour's Church in Ballybeg has asked the congregation to 'nod the sign of peace' to one another instead of the traditional shaking of hands as a part of the mass.
The request is not an official order but it is understood some priests in other dioceses are considering the same.
Elsewhere, there have been calls on the British government to provide more funding to tackle the virus in Northern Ireland.
DUP MP Iris Robinson said she wants the costs of vaccinations and other resources to be met by the British Treasury rather than 'an excessive burden' falling on Stormont.
It is understood that Stormont finance minister Sammy Wilson is still negotiating on funding for swine flu.
