Key points5

Spread through the fecal-oral route, often via contaminated water supplies.
Major outbreaks occurred in London in 1832, 1849, and 1854.
The Great Stink increased public fear of disease transmission.
John Snow identified the link between water pumps and cholera transmission in 1854.
The new sewer system effectively eradicated cholera in London by separating sewage from drinking water.

Summary

Cholera is an infectious disease caused by contaminated water that plagued 19th-century London.

Overview

Cholera is an acute diarrheal illness caused by the ingestion of food or water contaminated with the bacterium Vibrio cholerae. The infection primarily affects the small intestine, where the bacteria release toxins that disrupt the normal absorption of water and electrolytes. This disruption leads to the rapid onset of profuse, watery diarrhea, which is the hallmark symptom of the disease.

Without prompt medical intervention, the resulting fluid loss can lead to profound dehydration and electrolyte imbalances within a matter of hours. Clinical signs of severe cases include sunken eyes, cold skin, and extreme fatigue. Because the disease progresses so quickly, it remains a significant global health threat, particularly in areas lacking adequate sanitation and clean water infrastructure.
