WHO declares DRC Ebola outbreak a global health emergency

The World Health Organization declared an outbreak of a rare strain of the Ebola virus in the Democratic Republic of Congo a public health emergency of international concern on Sunday. The designation, known as a Public Health Emergency of International Concern, follows the identification of the Bundibugyo variant, which has not been detected for over a decade. The outbreak is centred in the eastern Ituri province, specifically within the Mongbwalu health zone.

As of the declaration, the crisis has resulted in at least 91 confirmed deaths and approximately 350 suspected cases. Congolese Health Minister Samuel-Roger Kamba confirmed these casualty figures on Sunday. Demographic data indicates that the majority of those affected are women aged between 20 and 39. The outbreak originated with a nurse visiting a health centre in Bunia on 24 April 2026, though the primary cluster of deaths involving four healthcare workers in Mongbwalu over four days prompted an initial WHO alert on 5 May.

This marks the second time the Bundibugyo strain has triggered a global emergency declaration by the WHO. A critical factor in the severity of the response is the current lack of medical countermeasures; there is no approved vaccine or targeted therapeutic drug for the Bundibugyo strain, although experimental vaccines are under development. This absence of standardised treatment protocols distinguishes the current crisis from previous Ebola outbreaks managed with existing immunisation strategies.

Reporting delays have complicated the containment effort, exacerbated by local community factors that have hindered timely data collection and response coordination. The fluid nature of the suspected case count, currently standing at around 350, remains subject to change as testing continues in the region. The epicentre in Mongbwalu remains the focal point for international health monitoring and resource allocation.

The declaration underscores the institutional challenge of managing rare viral strains in regions with limited healthcare infrastructure. With no approved therapeutic drugs available, the WHO’s intervention relies heavily on containment protocols and the rapid deployment of experimental countermeasures. The situation in Ituri province continues to evolve as health authorities work to stabilise the transmission chains identified in the initial healthcare worker cluster.
