Nina's Clinic

The year is 1854. You are Dr. John Snow, a physician in London. A serious outbreak is spreading through the Soho neighborhood. Hundreds of people have fallen ill with cholera — a disease that causes severe vomiting, watery diarrhea, and dangerous fluid loss. Without treatment, it can kill within hours. The outbreak is unusually concentrated: most cases are packed into a few blocks around Broad Street. The city's leaders and most doctors believe the disease comes from "miasma" — poisonous bad air rising from the filthy River Thames and London's open sewers. They think the terrible smell itself causes disease. But you have a different theory. You've studied cholera for years and don't think it spreads through air. You think it spreads through contaminated drinking water. Most doctors dismiss your idea. You have no microscope powerful enough to see the cause, and germ theory hasn't been developed yet. You need to prove your theory with evidence so clear that no one can ignore it.
