The White House is monitoring a plague outbreak in Russia after a laboratory technician died and roughly 200 people who had contact with her were placed under monitoring. The Trump administration is now weighing [1] its response as Russian authorities impose quarantines and other security measures.
An administration official told Axios on Sunday that officials are “aware, monitoring the outbreak, and assessing options.” The source did not detail which options are under consideration.
Darya Shipilova, 28, was reportedly working at the Irkutsk Anti-Plague Institute in Siberia when she was exposed to pneumonic plague. According to the news outlet Lyudi Baikala, Shipilova told medical workers that she had accidentally broken a test tube containing live bacteria.
Shipilova later became ill while participating in a field expedition with colleagues in Buryatia, near Russia’s eastern border with Mongolia. She was admitted to a hospital on September 29 and placed on a ventilator.
Shipilova died two days after being hospitalized. She had come into contact with roughly 200 people, all of whom are now being monitored because of concerns that the disease could spread.
At least three hospitals in the region have been placed under secure measures, and a mask mandate has been imposed. Health officials have also been pictured wearing hazmat suits in the Irkutsk region during the response.
☣️BREAKING: Plague outbreak expands, Russia BSL-3 lab accident – FIVE hospitals now quarantined ☣️
The plague outbreak in Siberia, Russia has expanded w/5 hospitals now under QUARANTINE: Irkutsk Hospitals No. 1, No.3, No.10, Ivano-Matreninskaya Children’s Hospital, and an unnamed maternity hospital (Lyudi Baikala news, Moscow Times).
Quarantine is NOT voluntary. Even in the U.S., quarantine is among the most extraordinary measures gov’t can impose on American citizens who haven’t been convicted, or even accused, of committing a crime. Quarantine means being forcibly confined and medically examined by law. U.S. quarantine can be imposed on anyone infected by a legally quarantinable disease listed below (this can change). One should assume Russia’s quarantine protocols are even more severe. As of 2026, under Executive Order 14047, legally quarantinable diseases in the U.S. are:
■ Plague
■ Smallpox
■ Viral hemorrhagic fevers
■ Cholera
■ Diphtheria
■ Yellow fever
■ Infectious tuberculosis
■ Severe acute respiratory syndrome (SARS)
■ Flu that can cause a pandemic

Irkutsk Governor Igor Kobzev said the people being monitored had not displayed symptoms and had tested negative for the disease, according to The Moscow Times. The hospital where Shipilova received treatment is among the medical facilities placed under quarantine.
The other quarantined medical facilities have taken in people who came into contact with Shipilova. The regional response comes as officials watch for symptoms among those who may have been exposed.
Pneumonic plague produces a severe lung infection. Its symptoms include fever, shortness of breath, and coughing up blood, and they typically begin appearing between three and seven days after contact.
Fatalities from pneumonic plague fall to around 17% when patients receive antibiotics within the first 24 hours of infection. The disease, however, is almost always fatal when it goes untreated.
WATCH:
Questions are also mounting over the official explanation for Shipilova’s exposure. Reports have claimed Russian authorities are trying to conceal exactly what happened at the institute.
Other reports claim that medications used to treat the disease are running out in the region. Frightened residents have reportedly crowded into pharmacies and medical facilities seeking supplies.
Mikhail Favorov, a senior Russian epidemiologist, dismissed the explanation involving the broken test tube, according to The Moscow Times. The Irkutsk Anti-Plague Institute, where Shipilova reportedly worked, was founded in 1934.
Favorov said: “It’s laughable. Someone working at the Anti-Plague Institute in Irkutsk wears a protective anti-plague suit.”
He continued: “If you break a test tube, the likelihood of infection is actually very low. In short, it doesn’t matter to the general public – they’ll believe the ‘broken test tube’ story.”
Favorov added: “It’s absolutely hair-raising. We will not be told what really happened.”
Pneumonic plague is one of three types of plague caused by the bacterium Yersinia pestis. It spreads when a person breathes in airborne droplets from another person.
Septicaemic plague causes a blood infection through flea bites or contact with infected animals. Its symptoms include internal bleeding and tissue turning black because of necrosis.
The third form is bubonic plague, also known as the Black Death. It is caused by flea bites and produces fever, chills, and painful swollen lymph nodes known as buboes.
The Black Death was notoriously responsible for the Great Plague of 1665, which killed at least a third of Europe’s population at the time. Meanwhile, the White House response remains under consideration as Russian officials monitor those exposed.
The Daily Mail contacted the White House, State Department, Centers for Disease Control and Prevention, and White House Office of Science and Technology Policy for comment. No additional response from those offices was included in the report.
