The claim that pneumonic plague is transmissible human-to-human is supported by WHO, CDC, and BBC sources, which all state person-to-person transmission occurs through respiratory droplets. The post's 'unlike bubonic plague' framing is faithfully reflected in the sources, and the extraction does not add anything the passage did not say.

A guest makes this claim. Listeners heard it, so it counts against the post, and on the guest's own record.

What was said

… Now, the thing that antibiotics don't do is solve the problem if you don't address it quickly, because once plague, plague is extremely virulent, and once it gets you, And the other thing is that I believe, I'm not sure about this, but I believe that pneumonic plague, unlike bubonic plague, is transmissible human to human.

What we found

Supports. The WHO states that pneumonic plague can spread from person to person through respiratory particles, and that person-to-person transmission is possible through inhalation of infected particles.[2]

Supports. The CDC says plague can sometimes spread from person to person through infected droplets, though it is rare and typically requires close contact.[3]

Supports. The BBC reports that human-to-human transmission of pneumonic plague is possible through coughing infected droplets that are breathed in by another person.[5]

Supports. A Ministry-style provider guidance document states that person-to-person transmission can occur with primary pneumonic plague and recommends droplet precautions for patients.[4]

Context. PolitiFact reports that experts consider person-to-person spread of pneumonic plague unlikely to spread quickly or widely in the current Russian lab-worker case. This concerns the likelihood of an outbreak, not whether transmission is possible, so it does not contradict the claim.[1]
