Global flu warning after UK hit
Northern hemisphere countries are being told by health experts to brace themselves for flu outbreaks.
There has been a well-publicised surge of cases in the UK during December with swine flu appearing to be the dominant of the three strains circulating.
But the European Centre for Disease Prevention and Control warned much of the rest of Europe was also beginning to see increases too.
Meanwhile, parts of the US and Canada have reported higher levels.
