Quick Summary

The World Health Organization reported on Saturday that they cannot confirm the cause of death for Darya Shipilova, a 28-year-old Russian lab worker who died in early October after being hospitalized while working at an anti-plague research institute in Siberia. Initial reports suggested she may have broken a vial containing plague bacteria, leading to concerns about a potential outbreak; however, tests on her colleagues were negative and no pathogens that cause high-threat diseases like plague or COVID-19 were identified. WHO emphasized that they need more information from Russian authorities to assess the risk accurately, stating that a laboratory-associated exposure cannot be ruled out entirely.

Story summary

A 28-year-old lab technician named Darya Shipilova died of pneumonic plague in Siberia after breaking a test tube containing the pathogen at the Irkutsk Anti-Plague Institute. About 200 people who came into contact with her were placed under quarantine, and three hospitals were closed as a precautionary measure. Russian authorities initially did not provide details about Shipilova's death or confirm if it was pneumonic plague, raising concerns among residents and media outlets that there could be a cover-up. The incident led Russia’s Chief State Sanitary Doctor Anna Popova to travel from Moscow to Siberia to oversee the situation. U.S. officials are monitoring the case closely with the CDC and other agencies, urging Russian authorities to share more information about the outbreak and its containment measures. Local epidemiologists downplayed fears of widespread transmission but acknowledged public concern due to similarities with previous viral incidents like the one in Wuhan. The White House is also reportedly aware of the situation and assessing options for response. Cooler weather is seen as a factor that could help contain potential spread, though public health protocols remain stringent.
