Asia Pacific|An Australian aid ship with a Covid outbreak has docked in Tonga.
An Australian naval ship carrying aid supplies arrived in Tonga on Wednesday, a United Nations spokesman said, a day after the Australian defense minister announced that 23 people aboard the vessel had tested positive for the coronavirus.
The ship, the H.M.A.S. Adelaide, docked in Tonga early Wednesday evening, Sione Hufanga, the United Nations spokesman in the remote Pacific nation, said in a telephone interview.
“It’s in front of me now,” he said. No one was entering the vessel, he added, and its cargo was being offloaded by machines.
Two weeks ago, Tonga was slammed by the world’s largest volcanic eruption in decades, and a tsunami that followed. The country was smothered with ash and swamped with water, complicating efforts to deliver aid, particularly in remote islands.
At least three people were killed, and the scale of the disaster is still coming into focus, in part because eruption cut off the nation’s lone connection to the internet. The outbreak on the Australian ship is stoking concerns that aid workers could inadvertently take the virus to Tonga, which reported its first and only case in October.
On Wednesday, Japan’s national broadcaster reported that the country’s Defense Ministry had suspended its aid mission to Tonga because several members of the Japanese Air Self-Defense Force — which has been delivering aid to Tonga since Saturday from a base in Australia — had tested positive for the virus.
Tonga requires arriving travelers to quarantine for 21 days, and about 60 percent of the country’s population has received two doses of a Covid-19 vaccine.
The H.M.A.S. Adelaide is one of several naval ships and planes that have delivered aid in Tonga, starting with a New Zealand Air Force cargo plane that arrived last week packed with relief supplies like generators, communications gear and shelter kits. One of latest was the U.S.S. Sampson, a guided missile destroyer, which the Pentagon said arrived in Tonga on Monday.
Peter Dutton, Australia’s minister of defense, said at a news conference on Tuesday that the 23 people aboard the ship who had tested positive for the virus were in isolation.
“We have a vessel obviously that we’re very keen, as quickly as possible, to dock in Tonga so that we can get those supplies off and provide the support to people,” Mr. Dutton said, adding that several planes had been used to unload supplies from the ship.
Mr. Dutton said the ship would attempt to deliver supplies safely if it were allowed to dock.
“Under no circumstance will we compromise the health and well-being of those Tongans, who have already had a concerted effort against the virus,” he said.
The Australian Department of Defense did not respond to requests for comment on Wednesday.
Tonga has a population of about 100,000 people. Its geographical isolation — the country’s main island is 1,100 miles northeast of New Zealand — has largely helped it to ward off an outbreak.
The country’s lone coronavirus case of the pandemic came from a person who arrived in October on a commercial flight from Christchurch, New Zealand.
