American Samoa recorded its first COVID-19 case this month, after a resident who returned from Honolulu on September 13 tested positive for the virus.

According to Radio New Zealand, American Samoa acting governor Talauega Eleasalo Ale said the traveller had tested negative three times prior to boarding the flight.

The person, who has been inoculated for COVID-19, is currently in isolation for 14-days.

Mr Ale said that locals, including government personnel, who came in contact with the traveller upon arrival in the territory had been placed in quarantine as well.

The positive case was identified among the 43 travellers in quarantine at Sadies by the Sea hotel in Utulei. And after testing 217 travellers in quarantine at Tradewinds Hotel in Tafuna, no positive cases were identified.

Health officials confirmed the traveller was asymptomatic when tested.

AS Health Department's epidemiologist Dr Aifili Tufa said contact-tracing process had already begun to identify all individuals, including travellers, who came in contact with the passenger, who tested positive.

"It's very hard for us to pinpoint where the traveller contracted the virus including in the US, but the Health Department has protocols in place for contact-tracing."

Meanwhile, American Samoa is continuing with all planned commercial flights between Honolulu and Pago Pago.

Only 7 countries in the world remain COVID-19 free to date. They include Tonga, Kiribati, Micronesia, Tuvalu, Nauru, North Korea and Turkmenistan.

Four other dependencies or territories in the Pacific - Tokelau, Niue, Pitcairn Island, and Cook Islands - also remain COVID-19 free as well as Saint Helena, a British Overseas Territory located in the South Atlantic Ocean, according to the World Health Organization.
