The World Health Organization (WHO) has stated that no confirmed cases of plague have been recorded so far following the death of a laboratory worker in Russia, while the cause of the pneumonia that took her life remains unknown.

According to a statement released on Saturday, Russian authorities reported that tests on the victim and those who had contact with him tested negative for the dangerous pathogens tested. Also, the contact persons did not show symptoms and no other cases of severe pneumonia linked to the event have been identified.

"WHO has not identified evidence of ongoing transmission associated with this event," the statement said, noting that the main uncertainty remains the lack of a confirmed diagnosis for the deceased employee.

Laboratory worker's death sparks health alarm in Russia

The employee, identified by Russian media as Darya Shipilova, 28, worked at the Irkutsk Anti-Plague Research Institute in eastern Siberia. She fell ill and died on October 2, under circumstances that have not been fully disclosed.

The case caused great concern, as authorities placed around 200 people in quarantine, while speculation spread on social media about a possible outbreak of pneumonic plague, a particularly dangerous form of the disease that affects the lungs.

The governor of the neighboring region of Buryatia stated that the woman may have died from the plague, but Russian health authorities said her diagnosis was pneumonia of unknown cause.

According to Rospotrebnadzor, the Russian health watchdog, post-mortem tests did not reveal the presence of the plague bacteria. Authorities also claimed that the employee was vaccinated and that no microorganisms related to her work were found in her body.

Quarantine and transparency requirements

Russian authorities announced that health checks on all people who had contact with the laboratory worker had been completed. A local official announced on October 6 that about 60 percent of those placed in quarantine had already been released.

Meanwhile, WHO Director-General Tedros Adhanom Ghebreyesus has asked Russia for clarification after media reports of a second staff member with pneumonia of undetermined cause. Moscow has dismissed the reports as disinformation. The United States has also demanded transparency from Russian authorities regarding the case.

At present, the WHO emphasizes that there is no evidence of ongoing transmission of the disease, but the cause of death remains unclear. Health experts continue to be cautious about cases of pneumonia of unknown origin, especially in the wake of the COVID-19 pandemic, which began with a cluster of severe respiratory illness cases in China.
