A retold version of the text JOHN SNOW DEFEATS “KING CHOLERA”Being a doctor, John Snow attended the sick to ease the pains of his patients. He then became inspired to help people exposed to cholera, the most deadly disease. He wanted to use his knowledge to help solve the problem. He tried to find the cause. He got interested in looking for the source of the disease. Some people then thought that the germs of this cholera must be multiplying in the air, without reason. They guessed that a cloud of gas full of the germs might float around finding its victims. There were other people who thought that the germs were absorbed into the body with the meals. They attacked the body. John Snow was one of those who believed in the second theory. He set out to test his idea. He found in the end that cholera germs were spreading through drinking water. He gathered information, found out the polluted water. He marked his findings on the map. He told the public that the germs in the water were to blame. By removing germs from the meals, John Snow helped to slow down the spread of cholera. And people were finally prevented from this deadly disease.
