The crisis concerns the heightened risk of cross-border Ebola Virus Disease transmission into Burundi following the confirmed Bundibugyo Ebola outbreak in the Democratic Republic of Congo (DRC) and Uganda. Burundi has not reported confirmed cases, but is exposed due to its proximity to affected areas in DRC and frequent formal and informal movement of people and goods across the Burundi–DRC border. The outbreak is evolving rapidly. According to WHO (6 June 26) DRC had reported 515 confirmed cases, including 91 deaths. Uganda had 19 confirmed cases, including two deaths, and one probable case who died. Cases in DRC have been reported from 25 health zones in Ituri, North and South Kivu, with Ituri accounting for 94% of cases. WHO assesses the risk as very high in DRC, high in Uganda, and high for countries sharing land borders with countries with documented Bundibugyo virus detection due to sustained population mobility, cross-border trade, variable readiness levels and differences in response capacity. For Burundi, the areas of highest concern are western border and lakeside communities with strong social and economic links to eastern DRC, including communities along Lake Tanganyika, key trade and transport corridors, and Bujumbura as a major commercial/transport hub. The areas include formal and informal crossing points, markets, transport routes and gathering places where early community-level action is needed to reduce the risk of local transmission. The main humanitarian concern is that one case could lead to local transmission in high-risk border and transit areas, particularly where awareness is limited, misinformation circulates, and access to timely referral and trusted health information is weak. Border communities, informal traders, fuel traders, transport workers, people using informal crossing points, caregivers, faith communities, refugees/returnees where relevant, elderly people and persons with disabilities are particularly exposed. A DERF response would be strictly non-clinical and community-based, focusing on trusted risk communication, rumor management, community engagement, early warning and safe referral messaging in coordination with local health authorities and specialised Ebola response actors. It would complement government and international preparedness efforts and help reach communities not sufficiently covered by health facilities.
