Study Notes
Dr. John Snow and Cholera
- Dr. John Snow studied cholera for over 20 years, initially aiding miners suffering from the disease due to poor sanitation.
- Common belief before Snow's research was that cholera spread through miasma, or contaminated air, rather than through ingestion.
- Snow suspected that cholera was caused by consumption of contaminated food or water because it primarily affected the digestive system.
- His experience as an anesthesiologist helped him understand the effects of gases, reinforcing his skepticism toward the miasma theory.
The Grand Experiment
- In 1840, Snow invented a regulator to ensure a safe, steady delivery of anesthetic gas to patients during surgery.
- He questioned why not everyone exposed to the same supposedly contaminated air contracted cholera, leading him to further investigate drinking water sources for affected populations.
- During an increase of cholera cases in London, various theories about its cause emerged, including the focus on pollution from nearby river neighborhoods.
