As seen from Figure 2, the initial and isolated cases were reported from UN House PoC in Juba starting on 26 May 2015. However, following epidemiological investigations on 27 May 2015, cases could be traced back to 18 May 2015. Cholera was eventually confirmed on 1 June 2015 in Juba after Vibrio cholerae inaba was isolated from the one of five samples tested in the National Public Health Laboratory. From 6 June 2015, sustained and consistently increasing community transmission was established in Juba as seen from the multiple transmission peaks. The highest transmission peak occurred on 19 July 2015 and was attributed to a funeral in Atlabara B. This trend is attributed to sustained community transmission in Kator, Rejaf, Northern Bari, Munuki, and Juba.

In Bor, the initial case occurred on 26 June 2015 with increasing cases from week 26 to week 27 when the highest transmission peak was registered. In the subsequent weeks, successively shorter transmission peaks were registered, a trend that is consistent with declining community transmission. Figure 2: Epidemic curve for cholera cases in Juba and Bor, 18 May – 1 August 2015
JS: Jonglei State; CES: Central Equatoria State; CFR: Case Fatality Rate
The probable risk factors fueling transmission include: residing in a crowded IDP camp with poor sanitation and hygiene; using untreated water from the Water tankers; lack of household chlorination of drinking water; eating food from unregulated roadside food vendors or makeshift markets; open defecation/poor latrine use; and attending/eating food at a funeral. Figure 3: Spot map for cholera cases by residence in Juba, 18 May – 1 August 2015
As of 1 August 2015, the sites reporting the majority of cases in Juba include Gumbo, New site, Juba 3 PoC, Gudele 2, Atlabara B, and Munuki with satellite cases distributed in seven Payams in Juba County (Figure 3). In Bor County, the majority of the cases originated from Malou 41 (36%) and Langbar 12 (10.4%) in Makuach Payam.

As seen from Table 5, 248 (89%) of the samples have been RDT positive while 43 (41%) have been confirmed by culture after the National Public Health Laboratory isolated Vibrio cholerae inaba. Most of the culture confirmed cases have been reported from Juba 3 PoC, New site, Munuki, and Nyakuron West in Juba while in Bor, Malou has registered the highest number of confirmed cases (Figure 4). Seven stool samples were shipped to the Central Public Health Laboratory in Uganda for testing. Vibrio cholerae Inaba serogroup, 01 serotype was isolated from one of the samples while six samples tested negative for cholera but were positive for nonpathogenic Escherichia coli. Three isolates were confirmed as positive and three negative samples tested negative on repeat testing in Uganda thus confirming earlier test results by the National Public Health Laboratory. The four isolates were sensitive to tetracycline and ciprofloxacin; intermediate for Ampicillin and chloramphenicol and resistant to Sulphamethoxazole.
