Russia plague alert as lab worker dies and 200 people are placed in quarantine

A laboratory accident in Russia has resulted in the death of a 28-year-old worker and the placement of nearly 200 individuals in quarantine. The incident occurred at the Irkutsk Anti-Plague Institute in Siberia, where the worker, identified as Daria Shipilova, accidentally broke a test tube containing Yersinia pestis, the bacterium responsible for plague.

Shipilova reportedly became ill several days after the accident and died in intensive care two weeks later. In response to the incident, 197 individuals who may have come into contact with Shipilova have been placed under medical observation, with over 100 of them hospitalized for monitoring. There has been no reported wider outbreak among those being monitored.

Plague is a serious disease caused by Yersinia pestis, with three main forms: bubonic, septicaemic, and pneumonic. The latter is particularly dangerous as it can spread between people through respiratory droplets. While Russian health authorities have not confirmed plague as the cause of Shipilova's death, describing it as pneumonia of undetermined origin, numerous reports continue to label the incident as a suspected case of pneumonic plague following the laboratory accident.

The priority for those placed under observation is to identify any signs of illness as quickly as possible, given the contagious nature of pneumonic plague. The case remains under investigation by Russian authorities, with the coming days expected to reveal more about the incident and whether any further exposure occurred.
