This infection first enter through mounth in to the body then to the small intestine by some strains of the bacterium vibrio cholerae. these symptoms may be mild to severe. John Snow was attacked by the weakest point that he could not identified the nature of the poison in water. By this John Snow got an opportunity to test the theory. He proposed a complete and correct model for the etiology of the disease. In the epidemiological field studies, he found that human sewage contamination was the major vector disease in human in london. He discovered that the poison came from the excreata of the cholera patient and it was mixed in the water and which was swallowed by new victims. Dr, John Snow shows the evidence that : a work house in that area had their own private well and by drinking that water there were 5 deaths among 535 inmates, After that brewery on Broad street never used that contaminated water for drinking from the Broad Street pump. But Snow died in 1858 without knowing actually causes the cholera.   cholera can be prevented by frequently handwashing, by brushing teeth, by drinking beverages like tea or coffee, before eating should wash the fruits properly, avoid eating or drinking from unknown sources. should eat home made things and should avoid contaminated things.
