7. Bubonic Plague
This plague is transmitted through infected fleas and ****s about 70 percent of its victims in 4-7 days. The most well known epidemic was the Black Death in Medieval times when it was rumored to have ****ed about 25 million in Europe alone and another 50 million across the world. The bubonic plague is often characterized by swollen lymph nodes though the modern world has seen few breakouts.
