US 'watching closely' after plague researcher dies in Russia, Rubio says

Meanwhile, the US notes it is closely monitoring the case of a Russian lab technician who died at a plague research centre in Siberia.

Key points

• It was in response to an outbreak in the 1920s that the Anti-Plague Institute of Siberia and the Far East, external was founded just over 100 years ago.
• The watchdog remarked a biological safety team had inspected the Anti-Plague Institute of Siberia and the Far East in Irkutsk and identified no emergency situation there.
• Kremlin spokesman Dmitry Peskov pressed residents not to "listen to various rumours" but "rely on Rospotrebnadzor's official statements" instead.
• Russian media documented last week that almost 200 individuals known to have had contact with the dead woman were under medical observation as a precaution.
• "Because this is Russia people's thoughts are running to that, but I think my earlier explanation is probably more likely, " Clarke remarked.

Secretary of State Marco Rubio remarked there was concern the incident could have led to the spread of pneumonic plague, but that there was no cause for alarm.

Announcing the cause of death as "pneumonia of undetermined etiology", Irkutsk's governor remarked that "no micro-organisms" linked to the woman's work had been identified "in her biological samples".

Unconfirmed reports had suggested the woman fell ill either after breaking a test tube containing the pathogen or after a field trip to a region where plague is identified naturally among wild rodents.

No other cases of staff from the plague institute seeking medical attention since her death had been documented, Irkutsk governor Igor Kobzev stated, quoting Russia's consumer and health watchdog, Rospotrebnadzor.

For context, the watchdog remarked a biological safety team had inspected the Anti-Plague Institute of Siberia and the Far East in Irkutsk and identified no emergency situation there.

Asked by a reporter for an update on the suspected plague case in Russia, Rubio remarked: 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 rapidly 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."

For context, the woman who died, whose first name was given by Russian media as Daria and who was in her late twenties, had lately visited the Buryatia region on the border with Mongolia.

Meanwhile, the plague bacterium or Yersinia pestis, external. It killed up to half the population of Europe in the 14th Century when it was known as the Black Death, is discovered among rodents such as marmots in the area.

Dr Simon Clarke, an associate professor in cellular microbiology at the University of Reading, informed BBC Radio 4's PM programme that the pneumonic version of Yersinia pestis was almost 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 remarked.

He continued: "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 remarked.

"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 employ as a bio-weapon, the scientist agreed it was feasible.

Taken together, the developments around US ' watching closely' after plague researcher dies in Russia, Rubio says point to a situation that is still moving, and the coming days should bring more clarity.
