Description, Abstract, or Artist's Statement

The bacterium Vibrio cholerae, when ingested, infects the intestines and causes a communicable diarrhea disease called cholera. Outbreaks of cholera occur in areas with poor sanitation and sewage treatments where fecal material of an infected person contaminates the water. These areas include Southeast Asia, Haiti, and sub-Saharan Africa, including Uganda. From 2011-2016, an analysis of Ugandan cholera data showed ‘hot spots’ of cholera cases in fishing communities with incidence rates as high as 120-998 cases per 100,000 people. An analysis of these same districts from 2011-2015 showed an average Case-Fatality Ratio of 2.4%, with the worst district as high as 5.8%. Interventions in Uganda to better dispose of feces, chlorinate pope water, and treat drinking water stopped a 2015 outbreak. Vaccination and drinking bottles that help remove bacteria from water may also be helpful in preventing outbreaks.
