Swine flu facts: the virus, the symptoms and treatment "Once seen, he was intubated and ventilated to assist his breathing and transferred to the intensive care unit at Maroondah Hospital the same day," Dr Lester said.
"Unfortunately, the man's condition deteriorated and he died on Saturday evening."
Swabs were taken and results confirmed the man had contracted swine flu, Dr Lester said.
She said that in most cases human swine flu remained a mild illness , and many people recovered without any medical treatment.
"However, we know that for people with chronic medical conditions, influenza can be severe," she said.
