Figure 1.
Annual number of cholera cases and deaths reported in Uganda 1997–2010.
There was a major outbreak in 1998 and a fluctuating, but persistent burden of cholera in the years since the outbreak.
Figure 2.
Districts with reported cholera cases from 2005 to 2010 (endemic and non-endemic districts).
Some districts may be considered endemic for cholera based on a history of cholera incidence during three of the five years from 2005–2010. Other districts have demonstrated cholera on a less consistent basis, while a few districts did not report any cases between 2005–2010.
Figure 3.
Age breakdown of cholera cases from non-random sample of cholera outbreaks, 2002–2010.
The percentage distribution of cholera cases in Uganda is similar to the overall age distribution of the population.
Figure 4.
Distribution of deaths by age group and average case fatality rate by age group.
The age distribution of cholera deaths varies slightly from age distribution of cases because the case fatality rates are higher infants and the elderly relative to other age groups.
Figure 5.
Map of reported cholera incidence by district, hospitalized cases, 2005–10.
The estimated incidence by district varies considerably in Uganda with a distinct pattern of low-incidence versus high incidence districts.

Figure 6.
Epidemic curves of cholera outbreaks in Uganda, 2002–2010.
The epidemic curves from a convenience sample of fifteen outbreaks shows both large and small outbreak have occurred during the period 2002–2010. There is considerable variation in the duration of outbreaks with longer outbreaks in districts with higher average annual incidence rates.
