The World Health Organization announced that the threat of a plague outbreak in Russia is low after the death of a 28‑year‑old lab technician at the Irkutsk anti‑plague institute. The statement followed the death of Darya Shipilova, who had fallen ill with pneumonia of unknown aetiology two days earlier.
Shipilova was a researcher at the institute that studies plague and other Yersinia species. Russian authorities said the disease was unrelated to her work, describing it as a pneumonia case.
WHO said it had received no evidence of further transmission and that the overall epidemic risk remained low. The institute has already been closed to external visitors.
The risk of an epidemic in Russia is low.
In the wake of Shipilova's death, Rospotrebnadzor imposed a 14‑day quarantine on 60 colleagues inside the institute and restricted access to several hospitals, including a maternity ward.
Pneumonic plague, the rarest and most lethal form of the disease, spreads through airborne droplets and can cause severe respiratory illness. Scientists warn that early detection and isolation are key to preventing a wider outbreak.
WHO will continue to monitor the situation and has requested that Russian health authorities keep detailed records of all close contacts. It also urged the public to seek medical attention if they develop symptoms after exposure.

The incident underscores the importance of rigorous biosafety protocols in research facilities dealing with dangerous pathogens. While the risk has been deemed low, the situation will be reviewed if new evidence emerges.
