The WHO report indicates no plague cases have been registered, and tests of the deceased and those she was in contact with were negative for high-threat pathogens. However, the organization calls for continued investigation due to uncertainty about the cause of death and lack of a confirmed diagnosis.

Story summary

A 28-year-old lab technician named Darya Shipilova died of pneumonic plague in Siberia after breaking a test tube at the Irkutsk Anti-Plague Institute on September 29, two days before her death. Around 200 people who had contact with Shipilova were placed under quarantine. Governor Igor Kobzev declared a mask mandate and closed several hospitals for three weeks as a preventive measure. Russian authorities are downplaying the severity of the situation, but there are concerns about potential cover-up efforts, similar to those seen during the early stages of the COVID-19 pandemic in Wuhan. The U.S. State Department is monitoring the outbreak closely with the CDC and other agencies, urging Russia for timely information sharing. Health officials stress that prompt antibiotic treatment can effectively manage pneumonic plague cases.
