Mankind's 13 Deadliest Diseases

Adam Starr | AllHealthcare

5. Cholera

According to the CDC, “Cholera is an acute, diarrheal illness caused by infection of the intestine with the bacterium Vibrio cholerae. Approximately one in 20 infected persons has severe disease characterized by profuse watery diarrhea, vomiting, and leg cramps. In these persons, rapid loss of body fluids leads to dehydration and shock. Without treatment, death can occur within hours.”

Because of modern American sanitation and sewage infrastructures, the risk for contamination in the United States is low, but travelers to Sub-Saharan Africa and India should be aware of the risks presented by the disease. Since cholera kills through severe dehydration, getting more and more people access to clean drinking water will continue to decrease incidents of infection.
