Russia Watch: Central Asian neighbours tighten border health checks as Russia insists Irkutsk lab worker did not die of plague

Several Central Asian countries have tightened health screening at their borders after the death of a laboratory technician at a Siberian anti-plague institute. Russian officials maintain that she died of pneumonia of unknown cause, not plague.

None of the reports reviewed for this update describe a border closure. Each describes stepped-up sanitary-quarantine checks at crossing points.

The World Health Organization (WHO) says it is in contact with Russian health authorities to verify the event, according to Politico Europe. Laboratory confirmation of plague has still not been made public.

What has changed since our last report

Central Asia. Tajikistan is checking the temperature of every person crossing its state border with contactless thermometers, according to Asia-Plus. The outlet cited Sayed Davlatzoda, a senior official at Tajikistan's Ministry of Health. Travellers are also asked about symptoms, and checkpoint staff have been advised to wear disposable protective clothing.

Kyrgyzstan's Ministry of Health said all its sanitary-quarantine checkpoints are on heightened alert, with surveillance of people, vehicles and cargo, Kazakhstan's state news agency Qazinform reported.

Kazakhstan's Ministry of Health said it is carrying out sanitary and quarantine controls at border crossings. It has found no passengers with elevated temperatures or suspected dangerous infections, and assesses the risk of importation as low, according to Qazinform and Tengrinews.

Uzbekistan's Committee for Sanitary and Epidemiological Welfare and Public Health said on 4 October that it had increased the readiness of health and sanitary services, Kun.uz reported. It noted that no laboratory-confirmed diagnosis had been announced.

WHO and Europe. A WHO spokesperson told Politico Europe that, under the International Health Regulations, the agency is in contact with Russian authorities to verify the event, the laboratory tests under way and the health of contacts. "Based on unofficial information available, the public health risk to the general population appears to be low," the spokesperson said.

European Commission spokesperson Eva Hrnčířová said the Commission is monitoring "very closely" and is in touch with the European Centre for Disease Prevention and Control (ECDC).

In a statement to Vital Signs, the ECDC said the suspicion of plague "is not yet confirmed." It said there were no reports of secondary cases or sustained human-to-human transmission.

Washington and Moscow. U.S. Secretary of State Marco Rubio said on 5 October that the United States was "watching and monitoring it closely," RFE/RL reported. "I don't think it's cause for alarm, but it is cause for focus," he said.

Kremlin spokesman Dmitry Peskov told journalists to rely on official statements from Rospotrebnadzor, Russia's federal public-health agency, "not listening to various rumours, various speculations," according to TASS (state media) as carried by Meduza and Lenta.ru.

The institute. More than 60 institute employees have been confined inside the building since 2 October, sleeping on floors and chairs while awaiting test results, according to sources who spoke to RFE/RL's Siberia.Realities. One relative said that by 3 October "not a single positive test had been found."

The official picture

The federal position has not changed. Rospotrebnadzor says the worker, named in media reports as Darya (Daria) Shipilova, 28, was diagnosed with "pneumonia of unknown etiology." It says expanded testing found no microorganisms linked to her professional work, and that no accidents involving pathogenic microorganisms were found at the institute.

Among contacts, the agency reported two COVID-19 cases and two rhinovirus cases and no other pathogens. Kazakhstan's health ministry put the number of contacts under medical observation at 197.

Irkutsk Oblast Governor Igor Kobzev said in a 5 October Telegram post that the situation was "currently stable." He said no new institute employees had sought medical care in recent days, RFE/RL reported.

bne IntelliNews reported that, according to Rospotrebnadzor, the commission also found no evidence of infection during a trip to Thailand. It said former Rospotrebnadzor head Gennady Onishchenko called the illness likely not plague.

Hospitals: conflicting accounts

Four Irkutsk hospitals, City Clinical Hospitals No. 1, 3 and 10 and the Ivano-Matreninskaya Children's Hospital, denied social-media claims that they had been closed for a three-week plague quarantine. bne IntelliNews reported the denials, citing Lenta.ru. City Clinical Hospital No. 1 said no cases of pneumonic plague had been officially confirmed in the city.

However, patients at Hospital No. 1 and the children's hospital told Siberia.Realities that relatives were barred and patients could not leave, according to Asia-Plus. Rospotrebnadzor has not explained why staff were isolated and hospitals restricted if tests were negative, Current Time reported, according to Euronews.

What could not be verified

No credible report was found that St. Petersburg has begun temperature or fever checks linked to this case. Searches in Russian and English found only older Rospotrebnadzor material on routine remote temperature screening at Pulkovo Airport.

An automated aggregator claimed temperature screening on flights from Irkutsk to Moscow. No news outlet or official source confirming this was found.

Reports that Central Asian countries "closed" their borders are not supported. Official statements describe stronger screening only.

Speculation and unverified claims

The claim by independent outlet People of Baikal that Shipilova broke a tube of plague bacteria on 25 September remains unconfirmed, and Rospotrebnadzor denies any accident.

What is still unknown

No public laboratory result for Yersinia pestis, the bacterium that causes plague, has been released. No WHO Disease Outbreak News notice has been published. The WHO says its risk assessment will be updated as more information becomes available. According to the WHO, plague is treatable with antibiotics if caught early.
