Story summary

In September 2023, a pneumonic plague outbreak hit Siberia after a lab worker named Darya Shipilova, aged 28, died at the Irkutsk Anti-Plague Institute in Irkutsk. She had reportedly broken a test tube containing plague bacteria while working and was admitted to hospital on September 29th before passing away two days later despite being placed on a ventilator. As many as 200 people she might have been in contact with were put under quarantine, leading the Russian government to implement strict measures like mask mandates in affected areas.

Russia's Chief State Sanitary Inspector Anna Popova traveled to Irkutsk following Shipilova’s death, but official statements from local authorities did not explicitly confirm it was pneumonic plague. Governor Igor Kobzev convened a special meeting of the regional commission on sanitation and epidemic prevention without specifying the infection involved. Despite this ambiguity, Russia's health watchdog Rospotrebnadzor has maintained that the broader situation in Irkutsk remains stable.

The incident prompted global attention; the White House and State Department are closely monitoring the situation along with U.S. intelligence agencies to assess potential risks for Americans in Russia and globally. The Centers for Disease Control and Prevention (CDC) is also involved, emphasizing early antibiotic treatment as crucial if pneumonic plague is confirmed. Concerns persist over whether Russian authorities will provide transparent updates on this developing health crisis.
