Russian officials reported on Tuesday that plague had not been detected among close contacts of a lab worker who died at an anti-plague laboratory in Siberia last week. Out of about 200 identified contacts, around 60% have been tested so far, with results showing two cases of COVID-19 and two of rhinovirus infection but no plague. The World Health Organization confirmed that Russian health officials stated there was no case of plague recorded in Irkutsk regarding the woman’s death.

Story summary
A 28-year-old female lab technician named Darya Shipilova died in Siberia after breaking a test tube containing the pneumonic plague pathogen at the Irkutsk Anti-Plague Institute on September 29. She was admitted to a hospital and placed on a ventilator but passed away two days later. Up to 200 people with whom Shipilova had contact were quarantined as authorities acted to prevent potential spread of the disease, which can be highly lethal if not treated early.
Russian officials did not immediately confirm the details publicly, leading some observers to question transparency around the incident. The outbreak raised concerns both domestically and internationally; the U.S. State Department acknowledged awareness of reports from Irkutsk Oblast, a region in southeastern Siberia, urging Russia for prompt sharing of accurate information about the situation. Health officials emphasized that pneumonic plague is treatable with common antibiotics if detected early enough. Despite the uncertainty surrounding full confirmation of the incident's details and scope, Russian authorities have implemented strict quarantine measures including sealing off hospitals and issuing mask mandates across affected areas to contain the outbreak. The White House has also been monitoring developments closely.
