The Bubonic Plague, also known historically as the Black Death, infected a child recently in Boise, Idaho.
The bubonic plague, while extremely rare, does still exist. According to ABC News, "Since 2000, the CDC has received reports of one to 17 cases of the plague per year. In 2015, 16 cases of plague were reported and, in 2016, there were only 4 cases." Typically, humans catch it after being bit by an infected flea. It's important to keep your pets flea-free, and to never handle wild rodents or animals that could carry fleas.
Symptoms include fever, chills, headache, weakness, and painful and swollen lymph nodes. The good news is that if caught in time, the plague is very treatable thanks to antibiotics!
