CHOLERA DYNAMICS IN ZIMBABWE FROM 1992-2012

The waterborne disease cholera has been endemic in Zimbabwe since the 90s. The cholera cases from the year of 2000 have been fluctuating from more than 1000 cases to more than 80 000 cases in 2008-2009 cholera epidemic. The decrease in water and sanitation from 1990 -2012 are the major reasons why cholera is endemic in Zimbabwe; rural: 71-69 % decrease in access to safe water; 35-32% decrease in sanitation, urban: 100-97% decrease in improved water; 54- 52% improved sanitation. As the improved water decreased there was a significant rise in (crude Case Fatality Rate) CFRs. It was shown that the CFRs have been rising and fluctuating from 1992, the statistical analysis using Fischer rejected the null hypothesis that within this period 1992-2009 there has been a significance change in the Crude Fatality Rate.
