Samoa's Health Ministry has confirmed that one of the 29 students from Australia has tested positive for influenza A/H1N1, the Samoa Observer reported on Wednesday.
All the other swabs sent were tested negative for the virus, General Manager of National Health Services Stanley Dean said on Tuesday.
Dean said so far no one else in the Pacific island country was suspected of having contracted the flu.
But treatment for the positive case and the other three girls who developed the flu-like symptoms last week have been completed.
Dean said that other members of the visiting Australian group are now taking Tamiflu pills.
All the visitors are expected to leave Samoa later in the week through Auckland, New Zealand.
New Zealand authorities have insisted that they take the pills three days before arrival, he said.
The six locals placed in isolation with the Australians at a motel will also be released at the end of the week under a schedule of taking their medicine over 10 days.
