Covid-19 positive case

American Samoa's Director of Health Motusa Tuileama Nua says the traveller was asymptomatic.

Motusa told KHJ News the all other travellers have yielded negative results.

This is the 11th positive covid test result detected in quarantine since American Samoa resumed commercial flights from Honolulu three months ago.

All of the confirmed cases have been asymptomatic.

The December 6 flight was Hawaiian Airlines' last commercial flight for the year.

The department said the man worked at the Holiday Inn hotel at Melbourne Airport, and it was contacting the hotel along with the case's close contacts.

The worker returned a negative test result on 4 February and returned to work on 7 February, where they developed symptoms and tested positive.

"We are contacting Holiday Inn Airport workers and others who are considered primary close contacts," the department said.

"They are required to immediately isolate, get tested and remain isolated for 14 days."

Warning in NSW

David Panuelo last week announced the sailor on the government ship, MV Chief Mailo, had tested positive after it returned from the Philippines.

He said the ship and its crew are isolated in the Pohnpei lagoon under heavy watch.

In a national address, Mr Panuelo said the crew was tested before they left the Philippines, and he allowed them to return because they feared for their safety.
