TWO children are being treated for flu in Temple Street Hospital in Dublin while another four have a cold-like virus that can sometimes cause serious illness.
A spokeswoman said the small number of flu cases at the hospital was not causing any disruption to services and the toll had been higher about six weeks ago.
The four other children have the RSV virus, which infects the lungs and breathing passages.
Meanwhile, visiting restrictions have been imposed at the midwest's largest hospital, University Hospital Limerick, to curb the spread of seasonal flu. Visiting is permitted during normal visiting hours only, with one visitor per patient.
Ten people have been officially confirmed as having died from the flu this winter and doctors are warning high-risk groups to be vaccinated as it continues to spread. Two children are among the casualties but the highest number of deaths have been among pensioners.
Swine flu is one of the dominant strains circulating since the beginning of winter and it has been been responsible for three of the deaths. It is now just like any other flu virus, and protection against it is included in this season's flu jab.
