Japan, Singapore and Thailand are the most recent countries to be added to the list of countries that travellers coming from or transiting through need to undergo 14 days self-quarantine.

This makes it a total of six counties on this list, including Mainland China, Hong Kong and Macau.

Travelers from these states or transiting through must spend at least 14 days at a country that is free of the 2019 novel coronavirus and must undergo medical clearance within three days before arrival in Samoa.

“In the event you arrive within the 14 day period as noted above, you will be returned to the country of last Port before arrival in to Samoa,” the Samoa Government Advisory reads.

The Government requires compulsory screening of all arriving passengers in Samoa with the policy now effective at all ports of entry.

All sea port entries will be screened at the quarantine buoy before the vessel docks at the wharf.

To date only four persons left in quarantine: two students and a Samoan woman with Kenyan husband who all flew in from mainland China.

Two Samoan sailors who transited through China last month were released on Saturday after getting quarantined upon arrival at the Faleolo hospital over a fortnight ago.

Nanai Laveitiga Tuiletufuga from the Government's Press Secretariat confirmed that one individual was deported last week as he transited through Hong Kong before arriving.

Travelers have reportedly been cancelling or missing flights due to flight restrictions imposed by the Samoa Government in its bid to keep the country free of coronavirus.

One traveler returning to Samoa, who did not want to be identified, could not check in for her flight to Samoa at the Brisbane Airport last week as she did not have a medical clearance.

As she was not an Australian resident and didn't have medical insurance, she had to pay a AUD$345 fee at a hospital in order to get medical clearance before she was allowed to board the flight to Samoa. 

All travellers originating from or transiting through certain countries and states are required to undergo medical examination by a registered medical practitioner within three days of arrival.

These countries include, South Korea, Taiwan, Canada, United Arab, Cambodia, Belgium, Australia, Germany, U.S.A. (California, Washington, Arizona, Illinois, Massachusetts, Wisconsin), Malaysia, Vietnam, France, India, Italy, Russia, Philippines, UK, Nepal, Spain, Finland, Sweden, Sri Lanka.

The medical clearance is required on check in prior to the issuing of passenger boarding passes.

For travellers outside of Samoa, it is strongly recommended that individuals intending to travel to China and any country affected by the virus postpone their travel arrangement, unless necessary.

Signs and symptoms of 2019 Novel Coronavirus that need to be looked out for include fever, cough, shortness of breath and breathing difficulties.
