A body with Covid washed ashore. Now this Pacific island nation isn’t taking any chances

A Pacific island country has banned outward travel from its main island for three days after a body washed ashore that later tested positive for Covid-19, Radio New Zealand has reported.

The body of a Filipino fisherman was discovered April 11 on a Vanuatu beach a short drive from the main wharf of the capital, Port Vila, on Efate island, according to the report.

That day, a United Kingdom-flagged tanker found one crew member was not aboard as it sailed out of Port Vila, New Zealand public broadcaster RNZ reported last week. Vanuatu port authorities told the tanker to return to port and a search and rescue operation got underway.

After the body of the crew member was found on the beach, authorities detained the tanker. The body was taken to a mortuary and later tested positive for Covid-19, according to RNZ.

It’s not clear from the RNZ report whether the man died from Covid-19 or how he came to wash ashore on the island. CNN has reached out to Ministry of Infrastructure and Public Utilities which overseas the Department of Ports and Marine for more information.

Most of the remote island nations of the South Pacific have reported very few coronavirus cases, and Vanuatu — home to around 300,000 people — is no exception. The country has reported just three Covid-19 cases, according to Johns Hopkins University. It reported its first case in November last year, and two more infections in March.

According to Prime Minister Bob Loughman, the travel ban is in place while authorities conduct contact tracing, RNZ reported.

As part of those efforts, 16 people have been put in quarantine — most of them police officers who went to the scene when the body was found, according to the report. The director-general of health, Russell Tamata, is urging the public to get tested, although he said the risk of community transmission was low, according to RNZ.

The leader of the opposition, Ralph Regenvanu, said on Twitter that although Vanuatu had imposed “admirably strict quarantine protocols on all ports of entry into the country,” they didn’t foresee that a dead body with Covid-19 could wash ashore and be put in “the only mortuary in the country where people gather to mourn every day.”

CNN has reached out to Vanuatu authorities for comment.
