the plague

The latest outbreak of the plague is alarming. Over the last two months, the World Health Organization reports 501 cases of plague – known as the Black Death to history buffs – on the island nation. Even more concerning: of those case, there's an 11 percent mortality rate. 
If recent headlines are to be believed, the plague is making a comeback as cases have popped up in Colorado and Michigan. However, these sensationalized reports are obscuring the truth, as the plague is actually more common in the U.S. than you may think. So everyone, relax.
