In 1854 a cholera epidemic broke out in the slums of London.

Cholera is characterized by rapid dehydration resulting from simultaneous vomiting, diarrhea, and profuse perspiration. As victims dehydrate, their skin darkens, shrivels and loses elasticity. Depending on the general health, body mass, age, and amount of ingested bacteria, cholera victims may suffer only mild symptoms or can die in less than an hour.

In 1854, hundreds died in the cholera epidemic. One man, Dr. John Snow, discovered the source and stopped the epidemic. You will be given the same information that Dr. Snow possessed and will try to solve the mysterious epidemic.

Your job as epidemiologist, is to find the source of the disease based on the information you have in your envelopes.

What did you conclude, as epidemiologist, about what caused the cholera epidemic in London in 1854?

Get out your map and write this conclusion (as a group) on the back of your map.
