Yes, this is the same illness that killed an estimated 50 million people across three continents in the 1300s, though these days common antibiotics will get rid of it.Once known as the Black Death for the dark patches caused by bleeding under the skin, the plague swept Europe 700 years ago, killing a third of the population — an estimated 25 million. It wiped out millions in China and Hong Kong in the late 1800s before people put two and two together and started targeting rat populations.
Centuries later, the plague periodically pops up in countries across the globe — though at minor levels compared to its medieval heyday. In 2015, the World Health Organization recorded 320 cases across the globe, including 77 deaths.
A flea-dwelling bacterium, Yersinia pestis, causes the scourge.
The U.S. tends to see between one and 17 human cases a year. According to the Centers for Disease Control and Prevention, the disease likely hitched a ride to the U.S. in 1900 on flea-infested rats, which had boarded steamships in Asia. Since then, infected fleas have taken up residence on rodents including chipmunks, squirrels and prairie dogs across the southwest.
