Russian health authorities announced that Daria Shipilova, a 28-year-old lab worker at an anti-plague institute in Irkutsk who died last week, did not have plague, despite initial speculation. Over 60 colleagues remain isolated inside the institute, with several hospitals in the region still under quarantine without clear explanation. Rospotrebnadzor reported that tests on Shipilova found no pathogens linked to her work at the institute and no accidents involving infectious materials were detected. However, two cases of COVID-19 and two rhinovirus infections among those who had contact with her raised concerns about the true cause of her death.

Story summary
A 28-year-old female lab technician named Darya Shipilova died in Siberia after breaking a test tube containing live bacteria at the Irkutsk Anti-Plague Institute on September 29, leading to her hospitalization and death two days later. At least 197 people who had contact with Shipilova were placed under quarantine to prevent any potential spread of pneumonic plague. The Russian government has not released an official statement but regional officials have taken swift action by placing several hospitals under quarantine measures. Irkutsk Governor Igor Kobzev declared a mask mandate in the area and Russia's Chief State Sanitary Officer, Anna Popova, visited the region to assess the situation. Reports suggest that while Rospotrebnadzor maintains the broader situation remains stable, there are fears this could be another "Wuhan situation," referencing the initial outbreak of COVID-19 in China. The U.S. State Department is monitoring the incident closely and urging Russia to share accurate information about the case promptly. Despite the concerns, pneumonic plague can still be treated with common antibiotics if administered early. The White House is also reportedly aware and assessing options regarding the situation.

Why this leaning score
This article does not take a side on a contested political
question, so it has no leaning score. That is an
answer rather than a gap: a match report or a rescue can be warmly
or critically written without being left or right, and scoring it
anyway is how approval of a subject gets recorded as a political
position.
