(AI Overview article from The GOOGLE.COM on 08 October 2026.)
A
28-year-old laboratory technician named Daria Shipilova died in Siberia after
contracting an undiagnosed pneumonia, triggering unconfirmed media reports and
international concern over a potential pneumonic plague exposure.
Shipilova
worked at the Irkutsk Research Anti-Plague Institute in Shelekhov (near
Irkutsk, Siberia). She was hospitalized on September 29, 2026, placed on a
ventilator, and died on October 2, 2026.
Russia’s
consumer health watchdog (Rospotrebnadzor) and federal officials officially
classify the death as pneumonia of unknown origin. They state that tests on
known contacts have returned negative for plague and that there is no risk of
an epidemic.
Unofficial media reports and a regional governor initially claimed she accidentally broke a test tube containing Yersinia pestis (the bacterium behind the Black Death) or caught it on a trip, leading to fears of pneumonic plague.
Quarantine
& Response: Nearly 200 people who came into contact with her have been
placed under medical observation or isolation as a precaution.
The
World Health Organization (WHO) has asked Russia for more transparency,
assessing the public risk as low to moderate. U.S. and European officials are
monitoring the developments, with leaders like President Donald Trump noting
plans to discuss the situation with Vladimir Putin.
US 'watching closely' after plague researcher dies in Russia
Donald
Trump says the US was looking "very strongly" at the case but had not
discussed it with the Kremlin. President Donald Trump says the US is looking
"very strongly" at the case of a Russian lab technician who died at a
plague research centre in Siberia.
Secretary
of State Marco Rubio said Washington was watching closely amid concerns the
incident could lead to the spread of pneumonic plague, but there was no cause
for alarm. Announcing the cause of death as "pneumonia of undetermined
etiology", Irkutsk's governor said "no micro-organisms" linked
to the woman's work had been found "in her biological samples".
Unconfirmed
reports suggested the woman fell ill either after breaking a test tube
containing the pathogen or following a field trip to a region where plague
occurs naturally among wild rodents.
Asked
what Washington was going to do about the risk of plague spreading from Russia,
Trump said he had not spoken to the Kremlin about it. "I hate to see them
having it," he said, but added: "We'll help. Everybody who has that
kind of a problem, we'll always help."
No
other cases of staff from the plague institute seeking medical attention since
the lab technician's death had been reported, Irkutsk governor Igor Kobzev
said, quoting Russia's consumer and health watchdog, Rospotrebnadzor.
The watchdog said a biological safety team had inspected the Anti-Plague Institute of Siberia and the Far East in Irkutsk and found no emergency situation there. Kremlin spokesman Dmitry Peskov urged people not to "listen to various rumours" but "rely on Rospotrebnadzor's official statements" instead.
Russian
media reported last week that nearly 200 people known to have had contact with
the dead woman were under medical observation as a precaution. Asked by a
reporter for an "update on the suspected plague case in Russia",
Secretary of State Marco Rubio said: "It seems that there was a worker at
the lab that was infected and there's concern that that, you know, could have
spread, at least internally - you've seen them do quarantine of this and that
nature.
"If
something like that gets out, it can quickly spread. So we're watching and
monitoring it closely. I don't think it's cause for alarm, but it is cause for
focus and the cause to just keep an eye on it and we're doing that."
The woman who died, whose first name was given by Russian media as Daria and who was in her late twenties, had recently visited the Buryatia region on the border with Mongolia. The plague bacterium or Yersinia pestis, which killed up to half the population of Europe in the 14th Century when it was known as the Black Death, is found among rodents such as marmots in the area.
It
was in response to an outbreak in the 1920s that the Anti-Plague Institute of
Siberia and the Far East was founded just over 100 years ago. Dr Simon Clarke,
an associate professor in cellular microbiology at the University of Reading,
told BBC Radio 4's PM programme that the pneumonic version of Yersinia pestis
was nearly always fatal if left untreated, but could be overcome with
antibiotics.
"Pneumonic
plague can transmit from person to person and that is why there is the concern
around this," he said. He added: "But of course people's thought with
any outbreak of infectious disease at all runs to... lockdowns and Covid and
that is just not what's going to happen here."
"People
think, 'Oh the plague, that's gone, that went hundreds of years ago,' but it
hasn't," Clarke said. "It's still around and in certain parts of the
world, it's a threat to human health and that's why they need to study
it."
Asked
if the pathogen might have been studied for potential use as a bio-weapon, the
scientist agreed it was possible. "Because this is Russia people's
thoughts are running to that, but I think my earlier explanation is probably
more likely," Clarke said.
According
to the World Health Organization (WHO), pneumonic plague has a very short
incubation period - sometimes just 24 hours - and can be fatal, if not
diagnosed and treated early.
People
can be infected through: infected flea bites, contact with bodily fluids or
contaminated materials, and the inhalation of respiratory particles. Symptoms
include shortness of breath and coughing, often with blood-tainted phlegm.
