Ukrainian Foreign Minister Andrii Sybiha said Russia's handling of a suspected pneumonic plague case fit what he described as Moscow's history of concealing information about dangerous incidents, citing the 1979 anthrax outbreak, the Chornobyl disaster, and the COVID-19 pandemic, according to his post on X on 8 October.

A 28-year-old worker at the Irkutsk Anti-Plague Research Institute, Daria Shipilova, died at Shelekhov District Hospital on 2 October. The hospital was placed under quarantine, and nearly 200 people who had contact with her were put under medical observation.

Sybiha has called on Russia to disclose all the facts surrounding the case, provide transparent epidemiological data, and cooperate with international mechanisms.

"Russia has a long record of concealing the truth: the 1979 anthrax leak in Sverdlovsk, the 1986 Chornobyl disaster, and the true scale of COVID-19 in 2020–2022," he said.

Plague is caused by the bacterium Yersinia pestis, which is usually found in small mammals and their fleas. Bubonic plague, the most common form, is caused by the bite of an infected flea. Pneumonic plague is the most virulent form: left untreated, it can be fatal within 18 to 24 hours of onset, though common antibiotics can cure it if given early.

But each time, the consequences were devastating.

Sybiha warns of the risks of secrecy

Sybiha added that there is compelling evidence that Russia has used chemical weapons in Ukraine and has threatened to use nuclear weapons in its genocidal war. His remarks came amid rumors that the plague could have originated in a biological laboratory developing weapons.

"The world must not wait for another catastrophe before asking questions," he said.

Russia must disclose all the circumstances surrounding the case, provide transparent epidemiological data, and cooperate with international mechanisms because “when dangerous pathogens are involved, secrecy is a threat to everyone,” Sybiha added.

WHO seeks more information from Russia

The World Health Organization (WHO) says it still lacks the data it needs for a full risk assessment, while Russia has told the organization that no cases of plague have recently been reported in Irkutsk Oblast.

WHO Director-General Tedros Adhanom Ghebreyesus says that the organization has asked Russia for "further information on the laboratory tests conducted on the individual who died and the contacts," more details on what prompted the public health measures, and the health status of the contacts. The organization also seeks verification of media reports of a second employee with pneumonia of undetermined cause.

Based on "unofficial information," the public health risk to the general population appears to be low, WHO spokesperson Christian Lindmeier says, according to Forbes.

US officials say they know little about what is happening in Russia

On 6 October, US Secretary of State Marco Rubio said information з приводу вирогідної хвороби from Russia was "still quite limited."

The next day at the White House, a reporter asked US President Donald Trump whether the plague in Russia was a bioweapon, according to CNN.

"Well, we don't think so. We're going to find out soon enough, but we don't think so," he said.

The reporter also asked whether Trump was “getting the same vibe right now from Russia that you got from China at the start of COVID.”

"Well, China didn't say much, and Russia's not saying much either, but they do say they have it very much under control,"  Trump answered.

Ukrainian drugmakers could lose the certificates that let them sell in Uzbekistan, their most important export market, Ukrainian business outlet Ekonomichna Pravda reported on 7 October. Uzbekistan is ending remote factory inspections next year, and industry sources say its inspectors are wary of traveling to a country at war.

Russia's war keeps reshaping Central Asia's trade with both warring countries: Ukrainian refinery strikes pushed Russian fuel shortages into the region, and Kazakhstan gained leverage over a Russian retail giant.

A market worth a third of export earnings

Uzbekistan brings in about 30% of the Ukrainian drug industry's foreign-currency earnings, and one in 10 medicine packs sold there is Ukrainian, Ekonomichna Pravda wrote. By the outlet's count, at least three of Ukraine's five biggest drugmakers by revenue rank it as their top foreign market.

The currency from Uzbekistan lets manufacturers keep prices low in Ukraine and absorb losses from Russian strikes, three industry sources told Ekonomichna Pravda. Losing the market would force producers to raise domestic prices or pull low-margin medicines, which "will hit the Ukrainian patient," said Hennadii Vovk, former deputy head of Ukraine's State Service on Medicines and Drug Control.

Exports reached $114 million in January–June 2026, more than in all of 2021, said Yevheniia Piddubna, government relations head at Farmak, Ukraine's largest drugmaker. She said Uzbekistan takes 35% of Farmak's exports.

Data from the YouControl business registry, cited by the outlet, complicates that picture. In 2022, 30–35% of Farmak's products went to Uzbekistan. In 2025, Uzbekistan was not among its direct buyers. Farmak explained that wartime currency rules cap payment terms at 180 days, while foreign buyers often demand longer. So part of its trade runs through the group's Polish company.

Remote checks end, and inspectors hesitate to travel

Uzbekistan grants three-year certificates of good manufacturing practice (GMP) after inspecting the factory. Since the pandemic, it has allowed remote checks. That suited Ukraine, where Uzbek experts avoided traveling because of Russia's invasion, industry sources told the outlet. Remote inspections end on 1 January 2027.

Most Ukrainian certificates expire within a year. Farmak's runs out in November 2026, and the company may not manage to renew it in time. Three producers renewed under the old rules until 2029: Darnytsia, the Borshchahivskyi Chemical and Pharmaceutical Plant, and Farmex Group. According to Piddubna, Uzbekistan's regulator has drafted rules for remote inspections in force-majeure cases, but nothing has been put into practice. Industry sources said the Uzbek Presidential Administration must sign off.

Producers have asked the Office of the President, the Foreign Ministry, and the Health Ministry to raise the issue with Uzbekistan's government, but no Ukrainian experts have been sent there yet, the outlet reported. Russia, whose share of the Uzbek drug market is almost the same as Ukraine's, is ready to take Ukraine's place, its sources said.

Armed escorts in masks pushed a group of migrants from Belarus toward Latvia and threatened Latvian soldiers, and hours later masked people crossed into Latvia and stole border surveillance cameras, Latvian Interior Minister Jānis Dombrava said on 6 October. Latvia's military described the incident as part of a continuing hybrid campaign on the border, and Ukraine's foreign minister blamed Moscow.

Russia keeps probing the EU's eastern defenses with migrants pushed from its own soil and through its ally Belarus, alongside drone incursions and sabotage that ISW has linked into one Russian pattern across Europe.

Armed escorts threatened Latvian soldiers

Latvian soldiers stopped at least 20 migrants trying to cross the border illegally from Belarus, the Latvian National Armed Forces said. Masked escorts led the group, and this time they were armed, threatened the soldiers, and urged and drove the migrants toward Latvia, the military said.

"Unlike many previous incidents, this time the provocation was particularly demonstrative and aggressive," Dombrava said.

The incident confirms that deliberate provocations and hybrid threats on the border will continue, the armed forces said. Illegal migration is being used as a tool to pressure Latvia's border and, with it, the external border of the EU and NATO, they added.

Belarus began funneling migrants toward the EU in 2021, a campaign Poland's government called a hybrid attack in which the migrants end up as weapons. In 2023, Finland closed its border crossings with Russia, accusing Moscow of the same tactic, and by mid-July Latvia had logged 111 straight days of migrants pushed across from Belarus.

Masked people stole the cameras

Several hours after the standoff, people in masks entered Latvian territory, damaged a distribution cabinet, and stole surveillance cameras, Dombrava said. They returned to Belarus before the border guard patrol could arrive.

"Belarus should understand that such incidents could lead to more serious consequences for Belarus itself," he said.

Ukrainian Foreign Minister Andrii Sybiha said Ukraine stands in full solidarity with Latvia. "Make no mistake: Moscow is behind it," he wrote, adding that Russian President Vladimir Putin "deliberately weaponizes migration, with the help of Lukashenka, to destabilise Europe."

Tunnels, tear gas, and damaged cameras on the border

Latvia's border guards stopped 11,384 attempts to cross illegally from Belarus between the start of 2026 and 24 September. In January, Latvia's armed forces and border guard published evidence that Belarusian security agencies were organizing illegal migration across the border. Latvia has also recorded deliberate damage to cables, distribution cabinets, and camera poles on its eastern border, aimed at slowing the rollout of an automated border control system.

On 22 July, Latvian soldiers fired warning shots and used tear gas against migrants trying to cross. The next day, Prime Minister Andris Kulbergs said Russia and Belarus were stepping up their hybrid war against the Baltic States to distract from Russia's failures in Ukraine. Latvia temporarily halted crossings on the Belarus border on 31 July. In August, Latvian guards found the first tunnel dug from Belarus and turned back 15 migrants who used it.
