Could the plague happen today?
The Bubonic Plague refers to a bacteria known today Yersinia pestis. Bubonic plague killed a third to one half of the world's population in the 13th-14th century. That would be 2.25 billion people if that happened today. Despite killing millions in the middle ages, the plague was never fully eradicated. About 2,000 cases are reported worldwide every year, it's not as deadly as we have antibiotics and advanced medicine and sanitation but if you don't get help within a few days, the prognosis if very grim. The plague is mostly in Africa and Asia where sanitation is poor. It's never been a major problem in America as the plague has only had a few isolated cases in the south, but if carelessness were to happen around a large population, it could happen all over again.
