SEOUL, South Korea >> On a recent nighttime visit to a drugstore, a double-masked Kim Jong Un lamented the slow delivery of medicine. Separately, the North Korean leader’s lieutenants have quarantined hundreds of thousands of suspected COVID-19 patients and urged people with mild symptoms to take willow leaf or honeysuckle tea.

Despite what the North’s propaganda is describing as an all-out effort, the fear is palpable among citizens, according to defectors in South Korea with contacts in the North, and some outside observers worry the outbreak may get much worse, with much of an impoverished, unvaccinated population left without enough hospital care and struggling to afford even simple medicine.

“North Koreans know so many people around the world have died because of COVID-19, so they have fear that some of them could die, too,” said Kang Mi-jin, a North Korean defector, citing her phone calls with contacts in the northern North Korean city of Hyesan. She said people who can afford it are buying traditional medicine to deal with their anxieties.

Since admitting what it called its first domestic COVID-19 outbreak one week ago, North Korea has been fighting to handle a soaring health crisis that has intensified public anxiety over a virus it previously claimed to have kept at bay.

The country’s pandemic response appears largely focused on isolating suspected patients. That may be all it can really do, as it lacks vaccines, antiviral pills, intensive care units and other medical assets that ensured millions of sick people in other countries survived.

North Korean health authorities said Thursday that a fast-spreading fever has killed 63 people and sickened about 2 million others since late April, while about 740,000 remain quarantined. Earlier this week, North Korea said its total COVID-19 caseload stood at 168 despite rising fever cases. Many foreign experts doubt the figures and believe the scale of the outbreak is being underreported to prevent public unrest that could hurt Kim’s leadership.

State media said a million public workers were mobilized to identify suspected patients. Kim Jong Un also ordered army medics deployed to support the delivery of medicines to pharmacies, just before he visited drugstores in Pyongyang at dawn Sunday.

North Korea also uses state media outlets — newspapers, state TV and radio — to offer tips on how to deal with the virus to citizens, most of whom have no access to the internet and foreign news.

“It is crucial that we find every person with fever symptoms so that they can be isolated and treated, to fundamentally block the spaces where the infectious disease could spread,” Ryu Yong Chol, an official at Pyongyang’s anti-virus headquarters, said on state TV today.

State TV aired infomercials showing animated characters advising people to see doctors if they have breathing problems, spit up blood or faint. They also explain what medicines patients can take, including home remedies such as honey tea. The country’s main newspaper, Rodong Sinmun, advised people with mild symptoms to brew 4 to 5 grams of willow or honeysuckle leaves in hot water and drink that three times a day.

“Their guidelines don’t make a sense at all. It’s like the government is asking people to contact doctors only if they have breathing difficulties, which means just before they die,” said former North Korean agriculture official Cho Chung Hui, who fled to South Korea in 2011. “My heart aches when I think about my brother and sister in North Korea and their suffering.”

Kang, who runs a company analyzing the North Korean economy, said her contacts in Hyesan told her that North Korean residents are being asked to thoroughly read Rodong Sinmun’s reports on how the country is working to stem the outbreak.

Since May 12, North Korea has banned travel between regions, but it hasn’t attempted to impose more severe lockdowns in imitation of China. North Korea’s economy is fragile due to pandemic border closures and decades of mismanagement, so the country has encouraged farming, construction and other industrial activities be accelerated. Kang said people in Hyesan still go to work.

The office of the U.N. High Commissioner for Human Rights expressed worry this week about the consequences of North Korea’s quarantine measures, saying isolation and traveling restrictions will have dire consequences for people already struggling to meet their basic needs, including getting enough food to eat.

“Children, lactating mothers, older people, the homeless and those living in more isolated rural and border areas are especially vulnerable,” the office said in a statement.

Defectors in South Korea say they worry about their loved ones in North Korea. They also suspect COVID-19 had already spread to North Korea even before its formal admission of the outbreak.

“My father and sibling are still in North Korea and I’m worrying about them a lot because they weren’t inoculated and there aren’t many medicines there,” said Kang Na-ra, who fled to South Korea in late 2014. She said a sibling told her during recent phone calls that their grandmother died of pneumonia, which she believes was caused by COVID-19, last September.

Defector Choi Song-juk said that when her farmer sister in North Korea last called her in February, she said that her daughter and many neighbors had been sick with coronavirus-like symptoms such as a high fever, coughing and sore throat. Choi said her sister pays brokers to arrange phone calls, but she hasn’t called recently, even though it’s around the time of year when she runs short of food and needs money transfers via a network of brokers. Choi said the disconnection is likely related to anti-virus restrictions on movements.

“I feel so sad. I must connect with her again because she must be without food and picking wild greens,” said Choi, who left North Korea in 2015.

In recent years, Kim Jong Un has built some modern hospitals and improved medical systems, but critics say it’s mostly for the country’s ruling elite and that the free socialist medical service is in shambles. Recent defectors say there are lots of domestically produced drugs at markets now but they have quality issues so people prefer South Korean, Chinese and Russian medicines. But foreign medications are typically expensive, so poor people, who are a majority of the North’s population, cannot afford them.

“If you are sick in North Korea, we often say you will die,” Choi said.

Despite the outbreak, North Korea hasn’t publicly responded to South Korean and U.S. offers of medical aid. World Health Organization Director-General Tedros Adhanom Ghebreyesus said Tuesday that the world body “is deeply concerned at the risk of further spread” in North Korea and the lack of information about the outbreak.

Choi Jung Hun, a former North Korean doctor who resettled in South Korea, suspects North Korea is using its pandemic response as a tool to promote Kim’s image as a leader who cares about the public and to solidify internal unity. He says the country’s understated fatalities could also be exploited as a propaganda tool.

“One day, they’ll say they’ve contained COVID-19. By comparing its death toll with that of the U.S. and South Korea, they’ll say they’ve done a really good job and their anti-epidemic system is the world’s best,” said Choi, now a researcher at a Korea University-affiliated institute in South Korea.
