Disease Mapping

In Episode 3, The Crowd & The Cloud travels back to 19th century London for an early citizen science success story. Scroll down to learn more about the people and projects featured in this segment.

Cholera in 19th Century London
FEATURED PROJECT
GOAL:

Mapping clues to find a killer.

In the mid 19th century, London was the largest city on Earth, with a population of more than two and a half million. And where there are travelers, there are often deadly diseases, often reaching epidemic proportions. Medical historian Richard Barnett guides us through the streets of London to tell the story of how medical detective work tracked down the water-borne causes of cholera. The first outbreak in 1832 killed more than six thousand people, and was followed by another in 1848 that killed sixty thousand. The causes of the disease were misunderstood until—in 1854—the celebrated physician John Snow, and a little-known clergyman, Henry Whitehead, found an entirely new way to think about the disease, pounding the pavements and talking to neighbors, until they discovered its cause. It’s a story of persistence, map-making and local knowledge solving a deadly epidemiological mystery with approaches that can now be mobilized with cellphones, sensors and crowdsourced disease data.
