According to papyrus literature, hemorrhagic fever existed in the Nile valley of Egypt in the Pharaoh's time from 1500 BC to 1350 BC. For more than 2000 years, hemorrhagic fever broke out in a large area on the east coast of the Mediterranean. For example, from 700 BC to 450 BC and 250 BC, hemorrhagic fever occurred in Mesopotamia. According to Thucydides, a Greek historian, the symptoms of plague in Athens from 430 to 427 BC were very similar to the Black Death. Justinian plague originated in Ethiopia and spread along the Nile Valley. In 54 1 year, it arrived in Syria, then in Asia Minor, Africa, Europe, and in 542 it arrived in Constantinople. It lasted until 700 ad, during which it broke out many times. Byzantine historian Procopius recorded the details of the plague, and its symptoms were very similar to those of the plague in Athens and the Black Death.
