Woman dies after infection at Siberian anti-plague laboratory in Russia

MOSCOW: A woman has died after reportedly contracting a dangerous infection linked to a laboratory in Siberia, raising concerns over a possible exposure at a facility specialising in plague prevention.

Russian authorities have launched an investigation into the incident, but officials have not yet determined what substance or infectious agent may have been released from the laboratory.

The woman reportedly developed an infection after being exposed at the anti-plague facility. Details about the exact cause of her illness and how the exposure occurred remain unclear.

Authorities have placed people who were in close contact with the woman under medical observation as a precaution. So far, tests carried out on those under monitoring have reportedly returned negative results, according to Russian officials.

Reports indicate that around 200 people have been placed under observation at a hospital in the city of Shelekhov, located in Russia’s Irkutsk region.

Health authorities are continuing to monitor those potentially exposed while efforts are underway to determine the source of the infection and whether any further risk exists.

The incident has drawn particular attention because anti-plague laboratories handle dangerous pathogens and are subject to strict biosafety procedures.

Officials have not confirmed that plague itself was responsible for the woman’s death, and the precise nature of the infection remains under investigation.

Authorities are expected to release further information as laboratory testing and epidemiological assessments continue. For now, officials are focusing on monitoring contacts and preventing any possible spread beyond the affected area.
