Suspected pneumonic plague kills Russian lab worker; ~200 under observation

scienceOct 5, 2026955,661

A 28-year-old laboratory researcher at the Irkutsk Anti-Plague Institute died after developing what Russian officials called “pneumonia of unknown etiology,” and nearly 200 people who had contact with her were placed under precautionary medical observation, local media and regional officials reported. Maksim Modin, mayor of the Shelekhov municipal district, said the inpatient facility where the researcher was treated was closed and quarantined. Russian authorities have not confirmed pneumonic plague as the cause of death; preliminary statements described the regional sanitary-epidemiological situation as stable. The World Health Organization notes pneumonic plague can spread person to person via respiratory droplets and can trigger severe epidemics, and medical experts say rapid antibiotic treatment is required to prevent fatalities. The White House and U.S. agencies including the Centers for Disease Control are monitoring the situation, and former White House Covid-19 response coordinator Dr. Ashish Jha said Moscow needs to provide more information while assessing that a large outbreak remains unlikely if the case is isolated.

And now we find that Russia is cultivating pneumonic plague in test tubes.

Not to be "that guy" but it is pneumonic plague not bubonic plague. Same bacterium but lung rather than lymphatic system. Different mode of transmission (person to person rather than by rats). Not better (maybe worse) but different...

It’s worse actually. Bubonic plague only has like a 30% fatality rate, while pneumonic is closer to 100% if untreated. It absolutely destroyed places in Europe that experienced it vs bubonic.

People need to understand the difference. They sure weren't getting it from Mr. "Which part of my frontal lobe is functioning today"

It's probably somewhat worse than bubonic, but any plague is very bad news. Fortunately, although pneumonic can be passed from person to person, it's far less contagious than Covid was. It also has a short incubation period (typically one to three days) and is treatable with antibiotics.

It's okay, I'm exactly "that guy/gal" also, and it can be blood borne sepsis (blood poisoning), buboes from infected rat/rodent fleas in the lymphatic system, or pneumonic as you said, and transmits airborne from coughs. All are Yersinia pestis bacterial infections, requiring early treatment.

Thank you for being "that guy". I was getting confused by the coverage since they were using the terms interchangeably which I was pretty sure was not the case. Still scary and the last pandemic is still too fresh in most of our memories.

The sad thing is that we will not get a fact-based report on what the pneumatic plague is, how it's transmitted, prognosis, treatment or what the U.S. is doing in concert with the rest of the world to prevent its spread. Can you imagine RFK Jr trying to do that?
