Quick Summary

The US CDC stated it is aware of a suspected pneumonic plague case in Russia involving Darya Shipilova, who worked at an anti-plague laboratory in Siberia and died under unexplained circumstances. Russian authorities have quarantined a hospital and placed nearly 200 people under medical observation. The CDC emphasized that the disease is treatable with antibiotics but noted it poses little risk to the US, while urging for rapid identification of infected individuals. U.S. officials are calling on Russia to provide more information about Shipilova’s death and the situation overall.

Story summary

A 28-year-old laboratory assistant named Darya Shipilova died in early October after reportedly breaking a test tube containing potentially dangerous pathogens at the Irkutsk Anti-Plague Research Institute in Shelekhov, Russia. Despite extensive speculation that she may have contracted pneumonic plague, Russian authorities continue to maintain that her death was due to pneumonia of unknown origin and have not identified the specific pathogen involved. At least 197 people who had close contact with Shipilova were placed under quarantine or surveillance, while international health organizations like the CDC remain vigilant but assert that the risk to other countries is minimal. The incident has sparked concerns about Russia's transparency regarding biological research and safety protocols at such facilities.
