A fourth case of swine flu has been confirmed in Ireland.
It is understood the infected person is a man from the south of the country who had recently returned from New York.
Department of Health Chief Medical Officer Dr Tony Holohan said the man is currently being treated for influenza A(H1N1) and that 'all necessary public health protection measures are being taken.'
This case is unconnected with the three previous cases confirmed in Ireland.
Both the Department of Health and the HSE say they would like to remind people of the measures which can be taken to help personal protection.
