The number of Australians diagnosed with swine flu has risen to 303.

Cases have been diagnosed in every state and territory, with the majority 212 in Victoria and 57 in New South Wales.

Schools have been closed in several states, as a way of minimising the impact on communties where people have come down with swine flu.

Health Minister, Nicola Roxon, says work has to continue to reduce the spread of the disease.

She says, “The aim is to make sure that we delay that for as long as possible in order to be able to ensure that when the disease really does attack the broadest number in the community that we are closer to the date of having a vaccine produced.”

She says “That way we can make sure that we can protect those that are most likely to be particularly vulnerable to the harder edge of this disease.”
