Mosquitoes, Yellow Fever, and a Deadly Medical Experiment
About this episode
The episode discusses a pivotal medical experiment involving mosquitoes and yellow fever that changed the understanding of tropical diseases.
On July 7th, 1896, something extraordinary happened in the Philippines that would transform our understanding of tropical diseases and save countless lives. The American physician James Carroll allowed himself to be bitten by mosquitoes as part of what would become one of the most daring medical experiments in history, though the most famous chapter of this research would unfold a few years later in Cuba. But let me take you back further to set the stage. Yellow fever was an absolute terror in tropical regions throughout the 19th century. The disease would strike without warning, turning its victims' skin a sickly yellow color as their organs failed. Entire cities would be paralyzed by outbreaks. The conventional wisdom of the time blamed bad air, or miasma, rising from swamps and rotting vegetation. Doctors and scientists were completely stumped. Enter Carlos Finlay, a Cuban physician who had a radical idea in 1881. He proposed that mosquitoes were transmitting yellow fever between humans. The medical establishment largely dismissed him. After all, how could such a tiny insect be responsible for such devastating epidemics? The idea seemed preposterous to most doctors who clung…
