The “The Ghost Map” is a book written by Steven Johnson, a well known science aurthorauthor. In the book, the author explains to us why urban planning is necessary to prevent deadly diseases, such as the deadly cholera outbreak. This book is a chronicle about an event that began on August 28, 1854, on Broad Street. A five-month-old infant named Frances Lewis, had developed diarrhea and exhaustion, which were both symptoms of cholera. Dr.William Rogers had taken care her, but she died within a few days.

John Snow, whose beliefs about contagion have been denied by the scientific community, but who is convinced that he knows how the disease is had spread. “The Ghost Map” records the outbreak’s spread and the despairing efforts to put an end to the epidemic - and solve the most urgent medical puzzle of the age. It was Dr. Snow’s "Ghost Map," that explained the connection between the water supply and the disease. This out break had drawn Dr. Snow’s attention because it was close to his house. Snow withe help of Whitehead, drafted on a map the 13 public wells, the 578 cholera deaths planned by home address, marked as black bars stacked perpendicular to the roads nearby Soho, and recorded the clustering of cases nearby one specific water pump on the intersection of Broad Street and Cambridge Street. He tested water samples from multiple wells under a microscope and verified the presence of an unknown bacterium in the Broad Street specimens. Despite heavy skepticism from the local authorities, he had the pump handle removed from the Broad Street pump and the outbreak immediately stopped. Dr. Snow theorized that cholera was reproduced in the human body and was spread through contaminated water. His theory opposed the prevailing theory that diseases were spread by
