Third plague pandemic

Bubonic plague pandemic, beginning 1855

The third plague pandemic was a major plague pandemic that began in Yunnan, China, in 1855. Its name refers to its status as the third of at least three known major pandemics caused by the spread of the bacterium Yersinia pestis. This episode of bubonic plague spread to all inhabited continents, and ultimately led to at least 15 million deaths worldwide, including 10-12 million in British Raj India and 2.2 million in China.
