The Ebola outbreak in eastern Democratic Republic of Congo has reached 1,003 confirmed cases, including 254 deaths, Congo's Ministry of Health announced late Sunday. Some 100 people have recovered since the outbreak was declared on 15 May, while 365 patients remain hospitalised or in isolation. Health authorities warn that the true scale of the crisis is almost certainly larger than official figures reflect, and that the peak has yet to be reached.
The outbreak, concentrated in Ituri province in the country's northeast, is caused by the Bundibugyo strain of the Ebola virus — a rare variant for which no approved vaccine or treatment currently exists. It has already been described as the worst first-month Ebola outbreak on record, with a 38 percent rise in cases recorded in just one week. The Africa Centers for Disease Control and Prevention Director-General, Dr. Jean Kaseya, underscored the severity of the situation, noting that authorities have yet to identify the index case — the first person infected. "If you want to control an outbreak, especially an Ebola outbreak, you must know the index case. We don't have confidence on when this outbreak started," he said.
Contact tracing remains a critical weak point. Authorities have managed to reach only about 55 percent of known contacts, far short of the 90 percent threshold the World Health Organization considers necessary for effective outbreak control. More than 35,000 people who have been in contact with infected individuals remain untraced as of last week.
The response is being severely hampered by the ongoing conflict in eastern Congo. Attacks by the Allied Democratic Force — a rebel group backed by the Islamic State — have cut off access to numerous villages and displaced large numbers of people, including those living in overcrowded displacement camps. Constant population movement makes it extremely difficult to track infections and isolate cases. Poor infrastructure in remote communities compounds the problem further. Health workers have also faced hostility from some communities resistant to public health measures; earlier in the outbreak, a hospital in Rwampara was set on fire by protesters seeking to recover the bodies of deceased relatives for traditional burial.
The outbreak has crossed an international border, with 19 confirmed cases and two deaths recorded in neighbouring Uganda, all linked to contact with patients in Congo. With contact tracing lagging, no identified source case, and active conflict obstructing access, health officials are warning that the outbreak continues to outpace the response — and that a significantly worse trajectory remains a real possibility.
