Pneumonic Plague in Russia: Low Risk of New Epidemic, Experts Say

The death of a Russian lab researcher has raised concerns about pneumonic plague, though health authorities attribute it to undetermined pneumonia and experts assess the risk of a new epidemic as low. The case has triggered international scrutiny and calls for transparency from Moscow. The researcher, Daria Shipilova, 28, died on October 2 after being hospitalized on September 29 in Irkutsk. Russian officials deny plague, citing no lab-related microorganisms, while the WHO has requested details and Central Asian countries have tightened border controls. Pneumonic plague spreads via droplets and is highly contagious but treatable with early antibiotics. The WHO rates the outbreak risk as "moderate to low" locally, "low" for Russia, and "very low" for Europe. Modern sanitation and short transmission chains make large outbreaks unlikely, though the bacterium persists in wild rodents across continents, including natural foci in Brazil's northeast and Teresópolis.
