The Ebola outbreak in the Democratic Republic of the Congo (DRC) has reached 5,515 confirmed cases and resulted in 2,642 deaths, marking it as the deadliest epidemic of the virus in the nation’s history. With 51 new cases recently detected in the Ituri and North Kivu provinces, government figures indicate that the case fatality rate has climbed to nearly 48 percent. This represents a significant increase from early June, when the fatality rate stood at approximately 20 percent.
DRCにおける感染状況と致死率の急上昇
The outbreak, which was declared in mid-May, is the 17th Ebola epidemic in the DRC and has been designated a Public Health Emergency of International Concern by the World Health Organization (WHO), the organization’s highest alert level. The epidemic is currently on track to surpass the 2014–2016 West Africa outbreak, which killed more than 11,000 people. While the case fatality rate has climbed to nearly 48 percent—meaning almost one in two infected people are dying—contact tracing efforts have improved sharply, rising from 30 percent in June to more than 85 percent.
レオ教皇による国際的な救援要請
At the Vatican, Pope Leo has offered prayers for the DRC and called for international action to help contain the epidemic. Addressing the severity of the situation, the pontiff urged the international community to respond in a manner that involves local communities in prevention efforts so that as many lives as possible can be saved.
ワクチン供給と臨床試験の展開
The current outbreak involves the Bundibugyo strain of the virus, for which there is no currently approved vaccine or treatment. However, the DRC government requested a release of Ervebo vaccines from the global stockpile managed by the International Coordinating Group (ICG). On Monday, the ICG informed the DRC government of an immediate initial release of 70,000 doses. Of that allocation, 20,000 doses are designated for a Phase 3 clinical trial to evaluate the vaccine’s impact on the Bundibugyo virus, while 50,000 doses are intended for frontline and health workers. Some 16,250 doses arrived in the DRC on Friday. While Ervebo is licensed for Ebola, early laboratory and animal data suggest it may provide some protection against the Bundibugyo strain.
封じ込めを阻む現場の障壁
Containment efforts have been hindered by armed conflict, displacement, and a mobile working population. Abdulsalami Nasidi, a public health consultant who helped establish the Africa Centres for Disease Control and Prevention (Africa CDC), stated that the outbreak is getting out of hand,
citing weak infection control measures and a lack of trust between authorities and affected communities. The virus has also exacted a toll on those fighting it; according to the WHO, approximately 160 health workers have been infected, and about 45 have died. The WHO and Africa CDC have emphasized the need for better support for front-line workers, including timely payment, access to rapid diagnosis, and protective equipment. Despite these challenges, the WHO noted that transmission has been interrupted in Uganda and several health zones in Ituri and South Kivu, providing evidence that rapid detection and community cooperation can break the chain of transmission.
