US Embassy Issues Urgent Health Warning for Americans in Russia
The U.S. Embassy in Moscow issued an emergency advisory on Tuesday, urging American citizens to leave Russia immediately due to concerns over a potential outbreak linked to a laboratory incident in Irkutsk. The warning cited reports of a 28-year-old researcher, Darya Shipilova, who died after allegedly breaking a test tube containing the bacterium responsible for pneumonic plague. The embassy emphasized that U.S. authorities have “limited capacity” to assist citizens if the crisis escalates, while advising those in the affected area to follow local health guidelines.
Several universities in Russia have canceled classes as part of precautionary measures, according to reports. The U.S. State Department has formally requested clarification from Russian authorities, with a source close to the matter telling AFP that the request was made. The embassy’s warning highlights growing uncertainty, as the U.S. continues to maintain its level 4 travel advisory ("Do Not Travel") for Russia, which has been in place since January 2022.
Russian Authorities Dispute Plague Claims, Initiate Quarantine Measures
Russian health officials have not confirmed that Shipilova’s death was caused by plague, instead describing her condition as “pneumonia of unknown origin.” However, the incident triggered quarantine measures, with around 200 individuals placed under medical observation and five hospitals reportedly closed. Rospotrebnadzor denied any emergency at the institute, stating that no plague cases had been recorded in the region recently.
According to reports, 189 people were placed under medical observation following the incident, with Russian health authorities stating that no plague cases had been detected among those in contact with Shipilova. FHI emphasized that it follows international health organizations’ guidelines and is tracking potential contacts of the affected individual.
WHO Calls for Transparency as Global Concerns Rise
The World Health Organization (WHO) reiterated on Tuesday that the risk of the outbreak spreading beyond Russia remains “very low,” but called for greater transparency from Russian authorities. WHO Director Tedros Adhanom Ghebreyesus stated that the organization had not yet received a full risk assessment of the incident, citing conflicting reports about Shipilova’s cause of death. “Rapid, complete, and transparent information sharing is critical to resolving contradictory reports and conducting an accurate risk assessment,” Tedros said.
WHO has also requested clarification on reports of another employee at the Irkutsk research institute who developed pneumonia of unknown origin. The agency emphasized that it has not yet conducted a full risk assessment of the incident, despite Russian health authorities’ claims that no plague cases have been recorded in the region. Norwegian health authorities, including the FHI, have stated they are following the situation closely but have not issued any national health advisories.
U.S. and International Leaders Press for Clarity
The U.S. State Department has formally requested clarification from Russian authorities, with a source close to the matter telling AFP that the request was made. Meanwhile, President Donald Trump announced plans to discuss the issue with Russian President Vladimir Putin in a call “very soon,” stating, “We will help them.” The U.S. has maintained its level 4 travel advisory (“Do Not Travel”) for Russia since January 2022.
USAs utenriksminister Marco Rubio has also urged Russia to share more information about the incident, as reported by Norwegian media. Trump’s comments came as the U.S. embassy’s warning highlighted concerns about the potential for a larger crisis, with the State Department emphasizing the limited capacity to assist American citizens if the situation worsens.
Pneumonic Plague Spreads Between People and Lacks Vaccine
Pneumonic plague, caused by Yersinia pestis, is a severe form of plague that can spread from person to person. While treatable with antibiotics, it is almost always fatal if not treated. The WHO noted that isolation and mask use provide good protection. Norwegian health authorities stated they are monitoring the situation but have no national recommendations at this time.
Current research indicates that there is no effective vaccine for pneumonic plague, but a vaccine based on the same technology as the most effective COVID-19 vaccines is undergoing testing.
Russian Officials Dismiss Reports of Additional Plague Cases
Russian officials have dismissed media reports of additional cases, with Kremlin spokesperson Dmitry Peskov urging the public to rely on official health authorities rather than “rumors and speculation.” However, international outlets have highlighted discrepancies between Russian health statements and the scale of quarantine measures. The U.S. embassy’s warning highlights growing uncertainty.
Reports suggest that Shipilova may have been exposed to plague bacteria after a test tube containing the pathogen broke in the lab. Norwegian media cited a lab accident theory, though Russian authorities have not confirmed this. Unverified reports also indicate another employee at the institute experienced similar symptoms, though officials have not confirmed this.
Expert Urges Transparency in Russian Plague Response
Bratlie emphasized that transparency from Russian authorities is critical to addressing public concerns and ensuring accurate risk assessments.

WHO Seeks Information from Russia on Deaths
The WHO is seeking more information from Russia to clarify the cause of Shipilova’s death and reports of another employee with pneumonia. The U.S. State Department has yet to confirm whether it will extend its travel advisory, but the embassy’s urgent warning suggests a heightened focus on safeguarding American citizens. As the situation evolves, the international community remains divided between calls for transparency and efforts to contain potential panic.
FHI also noted that it receives routine information from international health organizations and is tracking potential contacts of the affected individual. The agency emphasized that smitteverning (contact tracing) and follow-up of cases are likely to prevent further spread.
