A mysterious death at a Russian plague research institute has triggered quarantines and international monitoring — but there is still no confirmed outbreak.
The case centers on 28-year-old Darya Shipilova, an employee of the Irkutsk Anti-Plague Research Institute in Siberia.
Shipilova developed severe pneumonia and died on Oct. 2. Russian authorities officially describe the cause as “pneumonia of unknown etiology.”
Unconfirmed reports claimed she may have broken a test tube containing plague bacteria days before becoming sick. Russia’s health watchdog says it has found no evidence of such a laboratory accident or any link between her death and pathogens handled at the institute.
Authorities have nevertheless taken aggressive precautions.
Roughly 200 contacts have reportedly been placed under medical observation, while sections of hospitals in the Irkutsk region have been quarantined.
So far, no secondary plague cases have been confirmed. Several contacts tested positive for COVID-19 or rhinovirus instead.
The World Health Organization says the risk to the general public currently appears low, while U.S. and European officials are monitoring the situation.
One important distinction: pneumonic plague is not a virus. It is a bacterial infection caused by Yersinia pestis and can be treated with antibiotics when identified early.
Bottom line: something unusual clearly happened, but claims of a major Russian “plague outbreak” remain unproven.
