Park officials in Colorado have no choice: they must close the Rocky Mountain Arsenal National Wildlife Refuge. Why? Because an age-old and fatal disease has started to rear its ugly head again. Yes, certain animals have become infected with the plague – a deadly disorder that ran rampant across Europe in the Middle Ages. But the creatures to blame may well surprise you.
Rather unsettlingly, this isn’t the first plague outbreak in modern times. Various costal cities in the U.S. have had to deal with infestations of the disease, in fact, with Los Angeles being the most recent victim – until now, that is. And so when Colorado officials realized what was happening in August 2019, they acted quickly in a bid to prevent history from repeating itself.
