In cases of pneumonic and particularly septicemic plague, the progress of the disease is so rapid that there would often be no time for the development of the enlarged lymph nodes that were noted as buboes.

This blockage results in starvation and aggressive feeding behaviour by the fleas, which repeatedly attempt to clear their blockage by regurgitationresulting in thousands of plague bacteria being flushed into the feeding site, infecting the host. During this period many Jews relocated to Poland, where they received a warm welcome from King Casimir the Great.

Some modern scholars suggest that the symptoms and incubation period indicate that the causal agent may have been a disease similar to a viral hemorrhagic fever. It seemed no one was safe, as the disease hit Africa and made its way through the Americas as well.

The origins of the plague are disputed among scholars. The most authoritative account at the time came from the medical faculty in Paris in a report to the king of France that blamed the heavens, in the form of a conjunction of three planets in that caused a "great pestilence in the air".
