WHO seeks more information after Siberian lab worker’s unexplained death

A 28-year-old employee of an anti-plague research institute in Irkutsk, Siberia, died on October 2 after developing severe pneumonia, prompting quarantines and international concern over unconfirmed reports of pneumonic plague.

Russia’s public health agency, Rospotrebnadzor, said the woman died from pneumonia of unknown origin and that tests found no microorganisms connected to her work. Russian authorities said no plague cases had been detected among nearly 200 people placed under observation. By October 7, officials said about 90% of those quarantined had been released after nearly 5,000 tests found no dangerous pathogens.

The World Health Organization initially assessed the risk outside Russia as “very low,” but said Wednesday that it lacked enough information to determine what caused the woman’s death or conduct a full risk assessment. WHO officials urged Russia to provide further details. The European Centre for Disease Prevention and Control said it was also monitoring the situation and had seen no reports of secondary cases or sustained human-to-human transmission.

The United States renewed its warning against travel to Russia while monitoring the incident. President Donald Trump said he planned to discuss the case with Russian President Vladimir Putin and that the United States was willing to assist.

Pneumonic plague is a severe lung infection caused by *Yersinia pestis*. Unlike bubonic plague, it can spread between people through respiratory droplets and can be fatal without prompt antibiotic treatment.
