In Haiti, from the beginning of the epidemic (October 2010) to 28 October 2012, the total of cholera cases reached 606,951, of which 326,253 (54%) were hospitalized and 7,615 died. The global case-fatality rate is 1.2% and the hospitalized case-fatality rate is 1.5%. In general, comparing the 2012 and 2011 data by month and epidemiological week (EW), reflects that 2011 saw a higher number of cases and deaths than 2012. However, the distribution of cases and deaths has followed similar trends in both years with peaks coinciding with periods of heavy rain around May-June-July and around September-October.
