A lab technician in Siberia has died after reportedly coming into contact with plague bacteria, triggering emergency anti-epidemic measures across a Russian region.
Darya Shipilova, 28, worked at the Irkutsk Anti-Plague Institute, a facility that specialises in handling dangerous pathogens. According to regional media outlet People of Baikal, cited by the Daily Mail, she is believed to have broken a test tube containing Yersinia pestis, the bacterium behind plague, while working there in late September.
She became seriously unwell with what was described as “pneumonia of unknown” origin and was admitted to hospital in the nearby town of Shelekhov on 29 September, according to The Telegraph. She was placed on a ventilator but died within days, with different reports giving her death as either 1 or 2 October.
What happened next
Her death has prompted a rapid response from Russian health authorities. Around 197 people who may have had contact with Shipilova have been placed under medical observation, with more than 100 of them monitored in hospital, according to Euro Weekly News. A facility in Shelekhov was quarantined and a mask order introduced in Irkutsk.
Russia’s chief state sanitary doctor, Anna Popova, travelled to the region to personally oversee the response. Irkutsk governor Igor Kobzev said an “extraordinary meeting of the regional sanitary and anti-epidemic commission” had been held after “information that had emerged about a suspected case of a particularly dangerous infectious disease in a resident of the region”.
He added that all identified contacts had been placed under medical observation and that, as of his statement, none had shown signs of illness, with laboratory tests coming back negative. Alexei Tsydenov, governor of the neighbouring Buryatia region, said in a social media post that a woman in Irkutsk had “died of plague”.
Not everyone is convinced by the official account. Russian epidemiologist Mikhail Favorov questioned the “broken test tube” explanation, telling the Moscow Times that lab staff at the institute wear protective anti-plague suits, making infection from a simple breakage unlikely. He suggested the public would not be told the full story.
Shelekhov mayor Maxim Modin urged residents “not to spread rumours or unreliable information – use only official sources,” adding that it was “too early to draw final conclusions” ahead of specialist findings. There has been no formal confirmation of the case from Russia’s health ministry, and reports have varied on Shipilova’s exact age, with some giving it as 27.
Why it matters
Pneumonic plague is one of three forms of plague caused by Yersinia pestis, alongside bubonic and septicaemic plague, and is considered the most dangerous because it attacks the lungs and can spread between people through respiratory droplets. The World Health Organisation says it can be fatal if not diagnosed and treated within 24 hours of symptoms appearing, but recovery rates are high when antibiotics are given early.
The WHO continues to record human plague cases in around ten countries in recent years, though outbreaks remain rare and localised. Reports suggest the White House has also been monitoring the situation, according to Axios.
For now, officials say no further cases have been confirmed among those under observation, and the risk beyond the immediate area is considered low. The investigation into exactly how Shipilova was infected, and whether the official explanation holds up, remains ongoing.
