Epidemiology
Cholera is a major cause of epidemic diarrhea throughout the developing world. There has been an ongoing global pandemic in Asia, Africa and Latin America for the last four decades. In 2011, a total of 58 countries reported a cumulative total of 589,854 cases including 7,816 deaths (case fatality rate of 1.3%) to the World Health Organization (WHO). There was an 85% increase in number of cholera cases as a result of the Haiti cholera outbreak(https://www.cdc.gov/cholera/haiti/2010-outbreak-response.html) in October 2010. Resource-poor areas continue to report the vast majority of cases with the African continent having the worst case fatality rates.16
