Fleas May Have Caused the Black Death
WouterUntil now, scientists have been confused as to what exactly caused the black death. They have tried to determine whether rodents or fleas were responsible for the disease. But a new study suggests that fleas and lice on humans may be to blame. Researchers have used mathematical models to determine how plague spread from one place to another.
Although scientists still do not know what exactly caused the Black Death, they have some theories. One possible explanation is that fleas spread the plague from rat to human, which is what caused the plague in the first place. Researchers have found that fleas spread the plague through human blood. The Black Death began in the Himalayan Mountains, where people lived in crowded and dirty conditions. Infected rats carried the deadly bacteria Yersinia pestis, which the fleas ingested.
Researchers have used mortality records and mathematical models to simulate the spread of the disease. The researchers then tested the model against actual deaths and found that it closely matches the actual epidemic. The researchers then examined nine outbreaks of the Black Death that occurred in Europe between 1348 and 1813. The findings of this study will help us understand the dynamics behind the spread of plague and the factors that affected the death rate.
In addition to fleas, other factors may have contributed to the disease. One of those factors is the fact that rodent populations increase periodically, which means that flea populations increase along with the population.
