BANGKOK — For more than two years, the isolation of the Pacific archipelago nation of Tonga helped keep COVID-19 at bay.
But last month’s volcanic eruption and tsunami brought outside deliveries of desperately needed fresh water and medicine — and brought the virus.
Now the country is in an open-ended lockdown, which residents hope will help contain the small outbreak — and will not last too long.
"We have pretty limited resources, and our hospitals are pretty small," Tongan business owner Paula Taumoepeau said Friday. "But I’m not sure any health system can cope. We are lucky we’ve had two years to get our vax rate pretty high, and we had a pretty immediate lockdown."
Tonga is only one of several Pacific island countries to experience their first outbreaks over the past month. All have limited health care resources, and there is concern that the remoteness that once protected them may now make helping them difficult.
"Clearly when you’ve got countries that have already got a very stretched, and fragile health system, when you have an emergency or a disaster and then you have the potential introduction of the virus, that’s going to make an already serious situation immeasurably worse," said John Fleming, the Asia-Pacific head of health for the Red Cross.
Tonga was coated with ash following the Jan. 15 eruption of the massive undersea Hunga Tonga Hunga Ha’apai volcano, then hit with a tsunami that followed.
Only three people have been confirmed killed, but several small settlements in outlying islands were wiped off the map and the volcanic ash tainted much of the drinking water.
The nation of 105,000 had reported only one case of COVID-19 since the beginning of the pandemic — a Church of Jesus Christ of Latter-day Saints missionary returning to the island from Africa via New Zealand who tested positive in October — and authorities debated whether to let international aid in.
They decided they had to, but despite strict precautions unloading ships and planes from Australia, New Zealand, Japan, Britain and China, two Tongan men who worked at the capital’s Queen Salote Wharf handling shipments tested positive on Tuesday.
"Tonga is just out of luck this xjmtzywyear," said Samieula Fonua, the chairman of Tonga Cable Ltd., the state-own company that owns the sole fiber-optic cable connecting the nation to the rest of the world.
"We desperately need some good news."
The two were moved into isolation, but in tests of 36 possible contacts, one’s wife and two children also tested positive, while the others tested negative, the local Matangi Tonga news site reported.
"The highest priority now is the close contacts of these positive cases and whom they interacted with" since Jan. 29, Health Minister Saia Piukala was quoted as saying.
It was not clear how many people they might have come into contact with the dockworkers, but the government released a list of locations where the virus might have spread, including a church on two days, several shops, a bank on two days and a kindergarten during school hours.
Prime Minister Siaosi Sovaleni told reporters "some" of the five infected had started to show symptoms and were being quarantined at a medical facility. He imposed an open-ended lockdown starting 6 p.m. on Wednesday; one that could be particular arduous for Tongans because most have been without any internet connections since the volcanic eruption severed the fiber optic cable to the country.
The government has been primarily communicating with residents by radio addresses, and Fonua said his crews estimate they may have to replace an 87-kilometer (54 mile) section of undersea cable. Still, they were hopeful to restore service by next week.
One of the dock workers has now tested negative, but remains in quarantine, Matangi Tonga reported.
It is not yet known what variant of the virus has reached Tonga, nor who brought it in. Officials have stressed that the aid deliveries were tightly controlled, and that it is not yet proven the virus came in that way.
Sailors aboard the Australian aid ship HMAS Adelaide reported nearly two dozen infections after an outbreak on board, but authorities said it had been unloaded at a different wharf. Crew members aboard aid flights from Japan and Australia also reported infections.
A total of 389 port workers have now all tested negative, and no further positive cases were reported, Sovaleni told reporters in an update, Matangi Tonga reported.
"That is a good sign for Tonga," resident Tulutulu Kalaniuvalu, a 53-year-old former police official who now in private business told The Associated Press.
"The people are OK with the lockdown because they understand the reason why, so the corona doesn’t spread over our little country, but people hope it doesn’t last long because most of the people depend on the crops that we grow at our plantations and people need to go there."
Despite the optimism, experience from elsewhere in the pandemic, especially with prevalence now of the rapid-spreading omicron variant, suggests that Tonga faces an uphill battle in trying to contain the outbreak, Indonesian epidemiologist Dicky Budiman told The Associated Press.
Some 61% of Tongans are fully vaccinated, according to Our World in Data, but because the country has not yet seen any infections, there will be no natural immunity and it is not clear whether the shots were given long enough ago that they may now be less effective, Budiman said.
The global experience has been that when the virus hits such countries, the number of hospitalizations is very high, he said, recommending that the government immediately start offering booster shots and open vaccinations to younger children.
"If we race with this virus we will not win," he said in an interview from Australia. "So we have to move forward by protecting the most vulnerable."
The October case of the missionary with COVID-19 prompted a wave of vaccinations, and 1,000 people already showed up for a first dose after the current outbreak was detected, Kalaniuvalu said.
This is already starting to be seen in the Solomon Islands, which reported its first community outbreak on Jan. 19. With only 11% of its population fully vaccinated, the virus has been spreading rapidly with the Red Cross reporting that less than two weeks later, there are now more than 780 recorded cases and five COVID-19 related deaths.
Elsewhere, Fiji — still reeling from damage caused by Cyclone Cody in early January — has been battling an ongoing spike in cases, fueled by omicron, and cases have been reported for the first time in Kiribati, Samoa and Palau.
Palau has nearly its entire population fully vaccinated, while Fiji has 68% and Samoa 62%, but Kiribati is only at 33%.
The key to ensuring hospitals aren’t overwhelmed is to make sure more people get shots, Budiman said.
"These countries that choose to have this COVID-free strategy, they are very vulnerable," he said.
Kalaniuvalu said some people have questioned the decision to let the ships carrying aid in to Tonga, but most feel it was necessary to help through the aftermath of the volcano and tsunami, and that the islanders now just had to do their best to minimize the impact of the outbreak.
"To be honest with you, we were one of the luckiest countries in the world for almost three years, now it’s finally here in Tonga," he said.
"We, the people of Tonga, knew sooner or later the coronavirus would come to Tonga because the corona is here to stay."
