New Study Reveals Body Lice's Role in Spreading Plague

Research suggests body lice may have significantly contributed to past plague pandemics, challenging previous assumptions about transmission methods.

Overview

Body lice can efficiently transmit Yersinia pestis, the bacterium causing plague, through bites.
Experiments show lice can infect salivary glands, enhancing their ability to spread the disease.
Findings indicate body lice might have played a major role in the Black Death and other historical outbreaks.
This discovery adds complexity to the understanding of plague transmission beyond rats and fleas.
Further research is needed to determine the real-life impact of lice in historical plague cases.
