While the last major cholera outbreak in DR Congo's western provinces was in 2011, cholera is endemic in the eastern provinces, which experienced a resurgence of cases starting in July 2012. Over the course of 2013, ongoing violence and displacement in North and South Kivu, Katanga and Orientale provinces limited access to health care and life-saving vaccination services. Between January and September, more than 21,000 cases of cholera and 376 deaths were recorded with 99% of these cases in the eastern provinces. During the same time frame, more than 74,299 cases of measles and 1,160 deaths had been reported. (WHO, 31 Oct 2013)
In 2013, Katanga was the most-affected province with 13,726 cholera cases and 348 deaths, compared to 6,930 cases and 223 deaths in 2012 (OCHA, 15 Jan 2014). On 7 Dec 2013, the governor of Sud-Kivu officialy declared a cholera epidemic outbreak. More than 6,200 cases had been reported since the beginning of the year. (OCHA, 11 Dec 2013) Country-wide, a total of 26,440 cases of cholera were reported in 2013 (UNICEF, 28 Jul 2014).
Between 1 Jan and 1 Dec 2013, 86,264 measles cases and 1,372 deaths were recorded (WHO, 20 Dec 2013).
By the end of July 2014, 10,551 cholera cases had been reported - almost half the number of cases reported during the same time in 2013 (19,032) (UNICEF, 28 Jul 2014). By October, the total number of cholera cases in 2014 stood at just over 14,000, compared to just over 21,000 in 2013 (UNICEF, 20 Oct 2014). By then end of 2014, a total of 19,305 cases had been recorded (UNICEF, 29 Jan 2015).
Since the beginning of the year, 19,705 cases have been reported in DRC. As of 29 November, the following provinces had reported cases: South Kivu (4,906), ex-Katanga (4,565), Maniema (3,971), North Kivu (3,294) and ex-Oriental (2,969). A high number of cases are still reported in the province of South Kivu where the situation is particularly worrying because of the presence of camps hosting refugees from Burundi. Furthermore, there are concerns that the epidemic in Maniema could spread to other provinces of the country as observed during the 2011 cholera epidemic when areas of Kinshasa were also affected. (WHO,15 Dec 2015)

In spite of the observed reduction during the reporting week, the cholera outbreak in the Democratic Republic of the Congo remains a concern, with a high weekly incidence and new areas being affected. The cholera epidemic is active in eleven provinces and 66 health zones. The outbreak appears to be following three major river and lake routes, suggesting that these water bodies play an important role in transmission. Towards the east of the country, the affected areas are along Lake Tanganyika and Lake Kivu and the disease appears to be moving towards Lake Albert in the north-east. In the central region, the disease is affecting areas along the internal lakes and along the Congo River, up to Kindu and Maniema. In the western central area, the disease is affecting areas along the Kasai River. (WHO, 23 Oct 2017)

To be noted that while this bulletin was prepared, the completeness rate of the database shared was not of 100%. However, the overall decrease of the reported cholera incidence is clear as the incidence reduces in several provinces (notably North Kivu, South Kivu, Kongo Central, Sankuru, Tanganyika, and Ituri). The epidemic is still expanding to new areas in the Great Kasai, despite an overall reduction in the cumulative incidence. (UNICEF, 15 Dec 2017)
