The spread of swine flu across the country has worsened, with the death of a fifth victim in Sydney, taking the national death toll to 20.
The virus, once thought no more deadly than seasonal influenza, has become “unstoppable”, the World Health Organisation says.
The number of cases in Australia is expected to hit more than 10,000 today after jumping by 778 in 24 hours. Experts predict the worst is yet to come, with a surge in deaths expected next month.
But Australians may have to wait three months for a vaccine, with the Government ordering 21 million doses of the vaccine, not expected to arrive until October, when the worst of the epidemic is expected to have passed.
