Russian Lab Worker Dies of Pneumonia; Plague Link Unconfirmed

A laboratory worker at a Russian plague research institute has died, sparking fears of a possible infection, though experts say there is no evidence of a wider outbreak. The cause of death remains unconfirmed. The worker, 28-year-old Darya Shipilova, died on 2 October at the Irkutsk Anti-Plague Research Institute in Siberia after developing severe pneumonia. Russian health authorities have rejected links to pathogens handled there, and neither plague nor a reported lab accident has been independently confirmed. Around 200 contacts have been monitored as a precaution, with no confirmed plague cases reported. Experts note that a broken test tube alone would not prove exposure, and genetic matching would be needed to confirm any lab link. The case has drawn comparisons to past incidents, but no evidence currently ties the death to a laboratory release.
