Whose experiments first proved that fleas can spread plague?
Quick Answer
Researchers in the early 20th century, especially Paul-Louis Simond, demonstrated that fleas transmit plague between rodents and humans.
The Full Story
Paul-Louis Simond, a French physician, provided key evidence in 1898 that fleas transmit plague. His work showed that the bacterium could move from infected rodents to humans through flea bites rather than by direct contact alone. This was a major turning point in understanding one of history’s deadliest diseases. The finding helped explain plague outbreaks and led to better rodent and insect control measures. Simond’s experiments remain a landmark in the history of epidemiology and medical entomology.
