WHO Declares International Health Emergency Amid Deadly Ebola Outbreak

The World Health Organization (WHO) has officially declared an international health emergency in response to the escalating Ebola outbreak in the Democratic Republic of Congo (DRC) and Uganda. This declaration is designed to raise the alert level in neighboring countries and rally international support, as stated by the UN agency in Geneva. However, the WHO has made it clear that this does not equate to a pandemic alert. Recent reports indicate that there are eight confirmed and 336 suspected cases of this lethal fever disease in Ituri province, located in northeastern Congo. The situation worsened as the virus was detected in an Ituri returnee situated in Kinshasa, the capital, which is over 2,500 kilometers away. Tragically, two individuals infected with the virus traveled to Kampala, Uganda, one of whom has since died. As of Saturday, the WHO has reported 80 suspected Ebola-related deaths in Ituri, while the Africa CDC cites a total of 88 fatalities connected to the outbreak. Infectious disease expert Anne Cori from Imperial College London noted that the rising number of suspected cases suggests the outbreak may have gone unnoticed for several weeks or even months, complicating containment efforts like contact tracing. The increasing trend of suspected cases and fatalities in Ituri indicates a potentially far larger outbreak than currently recognized. This poses a significant risk of local and regional spread of the virus, especially given the already vulnerable neighboring countries due to travel and trade. The DRC provinces affected by the outbreak share borders with Uganda, South Sudan, and Rwanda. Notably, the most impacted area is grappling with not only a fragile security situation but also a humanitarian crisis coupled with considerable population movements. The region is also marked by numerous gold mines that are often sites of armed conflict, further heightening the risk of virus transmission. Historically, the Ituri and North Kivu provinces faced a significant Ebola epidemic from 2018 to 2019. At that time, a vaccine was available for the circulating Zaire strains. Unfortunately, there is currently no licensed vaccine for the Bundibugyo variant, the strain responsible for the ongoing outbreak. This variant has a case fatality rate of approximately 30%, as per a meta-analysis of outbreaks up to 2022, which is less than the 66% rate for the Zaire strain. The Bundibugyo variant has only been recorded in two previous outbreaks: in Uganda in 2007 with 37 deaths and in Congo in 2012 with 29 deaths. Therefore, the epidemiology surrounding this variant remains inadequately characterized, heightening concerns about the current outbreak potentially evolving into one of the largest recorded for an Ebola strain, excluding the Zaire variant. While Ebola is well-known as a contagious and life-threatening disease characterized by symptoms such as fever, fatigue, vomiting, diarrhea, and bleeding, it is transmitted through bodily contact and fluids, not via the air. Treatment options are critically limited, with the only available monoclonal antibody therapies being tailored for the Zaire variant. In light of this serious situation, WHO Director-General Tedros Ghebreyesus plans to convene an emergency committee as soon as possible to provide recommendations for the affected states. The WHO is encouraging nations to initiate national disaster protocols. Additionally, Doctors Without Borders is preparing for large-scale intervention in the affected regions, with emergency program head Trish Newport emphasizing that the rapid increase in cases and deaths is extremely concerning. This marks the 17th Ebola outbreak in the Democratic Republic of Congo since 1976. Historically, Ebola outbreaks typically begin with animal-to-human transmission, predominantly from bats. The catastrophic outbreak that occurred in West Africa between 2014 and 2015 resulted in over 11,000 deaths due to the Zaire variant. The most recent outbreak in the DRC, specifically in the southwestern province of Kasaï, resulted in 45 deaths between September and December 2025. Related Sources: • Source 1 • Source 2
