Another probable case of the H1N1 swine flu virus has been identified at a National School in Co Roscommon.

Parents of children at Roxboro National School, which is 8km from Roscommon town, have been advised to attend a meeting with HSE officials at the school at 3pm this afternoon.

It is believed the child attended class in a room used by first and second class pupils in the school.

Roxboro NS is a five-teacher school with more than 130 pupils.

The school was open until Tuesday of this week before closing for the summer holidays.

Elsewhere, the Department of Health and the HSE are refusing to confirm reports of a case of swine flu at Sligo General Hospital.

It is believed that a woman from the US who arrived in Ireland last Thursday has been hospitalised in Sligo and is being treated for the virus.

However, in a brief statement the Department said: 'Due to patient confidentiality, the Department does not comment on individual cases.

'In general terms, the Department would expect occasional hospitalisations and we are satisfied that hospitals are able to deal with such cases in an effective manner.'

There have been 49 confirmed swine flu cases in Ireland, with four in-country transmisisons. Eight cases were confirmed yesterday.
