A 28-year-old laboratory technician died from pneumonic plague in Russia’s Irkutsk region of Siberia, according to regional authorities and media reports. Health officials have placed nearly 200 people under medical observation following the death, which is linked to a suspected laboratory accident.
Laboratory accident leads to death of Daria Chipilova
The deceased has been identified as Daria Chipilova, a 28-year-old technician who worked at the Plague Control Institute in Irkutsk, btvnovinite.bg reported. According to the Russian publication “Peoples of Baikal,” Chipilova likely contracted the infection after a test tube broke during her work in the lab. While regional leaders have confirmed the death, the Russian Ministry of Health has not yet issued an official statement on the incident.
Medical observation for 200 contacts in Irkutsk
Authorities have placed approximately 200 people who may have had contact with Chipilova under quarantine, according to reports from AFP and the Moscow Times. Alexei Tsidenov, the governor of the neighboring Republic of Buryatia, confirmed via social media that a woman in the Irkutsk region had died from the plague. AFP noted that it has been unable to independently verify the specific details of the outbreak or the quarantine numbers.
Pneumonic plague spreads through airborne droplets
Pneumonic plague is one of three primary forms of the disease caused by the bacterium Yersinia pestis. According to the World Health Organization, this specific form is the most severe and rarest variant because it can spread directly from person to person through airborne droplets. If not treated promptly, the disease causes rapid development of severe pneumonia and carries an extremely high mortality rate, which often reaches 100%.
