Cholera Outbreak in the Southwestern Central African Republic

Cholera Outbreak in the Southwestern Central African Republic.

The outbreak was officially announced on Friday by Health Minister Pierre Somsé in a televised address. The first case was registered on June 14. Epidemiological data from Friday show: 197 confirmed cases 24 deaths, corresponding to a mortality rate of 12.2%. Cholera outbreaks in Africa are continuously monitored by the World Health Organization (WHO) and national health authorities. Considering the current status (as of mid-2024) regarding the Central African Republic (CAR), the Democratic Republic of Congo (DRC), and Uganda, the epidemiological situation must be precisely assessed. 1. Democratic Republic of Congo (DRC) – This is the epicenter of the region. The DRC is the most severely and persistently affected by cholera of the three countries. The country is in an endemic situation, which repeatedly escalates into severe outbreaks. The DRC is continuously recording thousands of cases. The provinces of Haut-Katanga, Tanganyika, South Kivu, and North Kivu are particularly affected. The ongoing violence and displacement by armed groups in eastern Congo are destroying water supplies and sanitation facilities. The refugee camps provide ideal conditions for the Vibrio cholerae bacterium. The DRC acts as a regional reservoir. From here, the virus is frequently spread to neighboring countries. 2. Uganda – these are imported cases and local outbreaks. Uganda regularly experiences cholera outbreaks, which are usually well contained. Uganda has reported several smaller outbreaks in recent months, particularly in districts bordering the DRC (e.g., in the Rwenzori region or around Lake Albert). The outbreaks in Uganda are often directly linked to the exodus from the DRC. As soon as Congolese refugees or Ugandan fishermen in the border region become ill, the disease spreads to local communities through contaminated water. Uganda has well-functioning surveillance systems and usually responds quickly with vaccination campaigns (oral cholera vaccination) and WASH (water, sanitation, hygiene) measures in the affected border districts. 3. Central African Republic (CAR) – these are localized outbreaks. The CAR does not have the massive number of cases seen in the DRC, but it is highly vulnerable and experiences recurring local outbreaks. There have been isolated cholera outbreaks recently, particularly along rivers (such as the Oubangui) or in areas with large numbers of internally displaced persons (IDPs). The country has suffered from decades of instability. Medical infrastructure is weak, and a large portion of the population lacks access to clean drinking water. The CAR borders the DRC to the south. There is constant cross-border traffic (trade, migration). If outbreaks occur in the CAR along the border with the Democratic Republic of Congo, there is a risk of the disease spreading along trade routes. The spread does not usually occur as a directed chain (CAR infects DRC, DRC infects Uganda), but rather via cross-border corridors. The DRC is the main reservoir in Central and East Africa. Movements of refugees and traders between the CAR and the Democratic Republic of Congo, as well as between the DRC and Uganda, lead to a constant risk of cross-border transmission. Fishing communities on the large lakes (Lake Kivu, Lake Victoria, Lake Albert) are particularly vulnerable, as they often move across national borders without regard for national borders. The current situation in all three countries is exacerbated by the following factors: 1. Extreme weather events such as flooding (e.g., at Lake Victoria or in the Congo Basin) wash fecal matter into drinking water sources. 2. Armed conflicts in the CAR and the DRC lead to massive displacement. Cholera spreads rapidly in overcrowded camps without latrines. 3. The WHO has been warning of an acute shortage of cholera vaccines since 2023. As a result, reactive vaccination campaigns in the DRC, CAR, and Uganda have often had to be scaled back (e.g., administering only one dose instead of two to reach more people). The cholera situation in the region (CAR, DRC, Uganda) remains critical and unstable. While the DRC is the epicenter with the highest number of cases, Uganda and the CAR act as vulnerable neighboring countries, repeatedly registering imported cases through cross-border movements. As long as basic water and sanitation services in the conflict zones are not improved, the disease will continue to circulate in the region.
