The document summarizes information about the Black Plague pandemic that occurred in Europe in the mid-14th century. It killed an estimated 75 million people, reducing the English population by over half. Fleas on infected rats spread the plague to humans. Symptoms included swollen lymph nodes, high fever, coughing up blood, and a pink rash. Death often occurred within a week of symptoms appearing. The plague devastated populations and traditional burial methods could not keep up with the death toll.
