John Snow is considered the father of epidemiology.
John Snow, a British physician, is renowned for his groundbreaking work in identifying the source of a cholera outbreak in London in 1854. His meticulous investigation and use of mapping to pinpoint the Broad Street pump as the source of the contamination established fundamental principles of epidemiology. Snow's efforts went beyond simply identifying the source; he persuaded local officials to remove the pump handle, effectively halting the outbreak.
Snow's approach was revolutionary for his time and laid the foundation for modern epidemiological methods. He challenged the prevailing miasma theory, which attributed disease to "bad air," by demonstrating that cholera was a waterborne disease.
His work included:
- Data Collection and Analysis: Snow meticulously collected data on cholera cases, noting the addresses of those affected.
- Mapping: He created a map showing the spatial distribution of cholera cases, which revealed a cluster around the Broad Street pump.
- Hypothesis Testing: Based on his observations, Snow hypothesized that cholera was transmitted through contaminated water.
- Intervention: By removing the pump handle, Snow tested his hypothesis and successfully prevented further cases.
| Feature | Description |
