The medieval plague known as the Black Death is making headlines this month.

In Mongolia, a couple died of bubonic plague on May 1 after reportedly hunting marmots, large rodents that can harbor the bacterium that causes the disease, and eating the animal’s raw meat and kidneys – which some Mongolians believe is good for their health.
