WELLINGTON, New Zealand (AP) — The leader of the small Pacific nation of Samoa appealed for calm Thursday after the country reported it’s first positive test for the coronavirus, although a second test on the same patient returned a negative result.

Prime Minister Tuilaepa Sailele Malielegaoi addressed the nation live on television and radio, urging people to remain vigilant with their virus precautions.

Samoa was among a dwindling handful of nations to have not reported a single case of the virus.

According to the Samoa Observer, the prime minister said the patient was a sailor who had been staying in a quarantine facility since flying in from New Zealand on Friday. He said the sailor returned a positive test four days after arriving, but then a second test on Thursday returned a negative result.

The prime minister said the Cabinet would meet Thursday to decide on any changes to the current virus settings, the Observer reported. Samoa is home to about 200,000 people.
