Pneumonic plague is spread through the air and can be passed from person to person through coughing, according to the World Health Organization. It is caused by the same bacteria that occurs in bubonic plague — the Black Death that killed an estimated 25 million people in Europe during the Middle Ages. While bubonic plague which is usually transmitted by flea bite can be treated with antibiotics if diagnosed early, pneumonic plague is one of the deadliest infectious diseases. According to the WHO, humans can die within 24 hours of infection.
