Bubonic plague, previously known as the Black Death, is a bacterial infection caused by Yersinia pestis, spread by fleas living on wild rodents such as marmots, and is characterised by symptoms including fever, chills, headaches, swelling in the lymph nodes under the arms, in the neck, and groin.

It had caused a global epidemic of bubonic plague that occurred in the mid-1300s. It majorly affected Europe and Asia killing around 200 million people worldwide. This is considered as one of the most fatal pandemics recorded in human history.
