Where Did the Pneumonic Plague Come from?

Pneumonic plague occurs when Y. pestis infects the lungs. This type of plague can spread from person to person through the air. Transmission can take place if someone breathes in aerosolized bacteria, which could happen in a bioterrorist attack.

What was the pneumonic plague and how was it caught?

Pneumonic plague occurs when the Y. pestis bacterium is inhaled. The disease may be spread through face-to-face contact when an infected person coughs or sneezes. Because it enters the body by being inhaled, pneumonic plague could be spread intentionally if the bacteria were put into aerosol form.

Does the pneumonic plague still exist?

The plague is most prevalent in Africa and is also found in Asia and South America. In 2019, two patients in Beijing, and one patient in Inner Mongolia, were diagnosed with the plague, according to the Chinese Center for Disease Control and Prevention.
