Al Jazeera English - H1N1 virus spreads to 160 countries

The H1N1 flu virus has spread to at least 160 countries across the world, the World Health Organisation (WHO) has said.

The global virus, which the UN health agency declared a pandemic in June, has resulted in nearly 800 deaths worldwide since it was first detected in Mexico four months ago, WHO officials said in Geneva, Switzerland, on Friday.

'The spread of this virus continues, if you see 160 out of 193 WHO member states now have cases, so we are nearing almost 100 per cent, but not quite yet,' said Gregory Hartl, a WHO spokesman.

'For the moment we haven't seen any changes in the behaviour of the virus,' he said.

'What we are seeing still is a geographic expansion across countries.'
