WHO probes Russian plague researcher's death amid pneumonic plague speculation

The World Health Organization is investigating the death of a researcher at a plague research center in Russia. The 28-year-old scientist died Friday at a hospital near Irkutsk, with speculation suggesting she may have contracted pneumonic plague in a laboratory accident. Russian health authorities reported no recent plague cases in the Irkutsk region, according to WHO Director-General Tedros Adhanom Ghebreyesus. He stated that an epidemiological investigation is underway, with identified contacts placed under medical observation and testing, though no severe pathogens have been detected among them. The WHO has requested further information to clarify the cause of the acute pneumonia and reports of a second employee with unexplained pneumonia. Tedros emphasized that timely, complete, and transparent information sharing under international health regulations is essential for assessing potential public health risks.
