Cholera symptoms are usually mild, but in some extreme conditions, they can be fatal if left untreated. Cholera mostly prevails in poverty and places affected by natural disasters or war. People in these places live in crowded conditions, and they don’t have access to proper sanitation. Cholera symptoms show its effects within a few hours of infection. In some cases, it may also take 3 to 5 days. Cholera is a type of infectious disease that will cause watery diarrhea, eventually leading to dehydration. If it is left untreated, it can lead to death. Cholera is caused by drinking water or eating food that contains a bacterium known as Vibrio Cholerae. During the 1800s, a large population of the United States was affected by cholera. But after the modernization of the water and sewage systems, the rate of this disease has lessened. Usually, cholera symptoms are not severe. But sometimes, it may be serious as well. 1/20th of every cholera-infected person suffers diarrhea and vomiting, leading to dehydration.
