Ebola surges in Congo: 782 cases and 181 deaths

The Ebola outbreak in the Democratic Republic of Congo has entered a phase that is alarming even to European health authorities: as of June 15, the country had reported 782 confirmed cases and 181 deaths, with 72 new infections logged in a single day. For Serbia, which monitors precisely these cross-border risks through the Batut Institute, the figure is not abstract. The European Centre for Disease Prevention and Control has already stepped up surveillance along air corridors, and the pandemic years showed just how quickly a distant outbreak can become a domestic concern.

The fatality rate in the current outbreak stands at roughly 23 percent, lower than historical averages for Ebola, but the daily influx of 72 new cases shows that the response is lagging behind the spread. More than 90 percent of cases are recorded in Ituri province, in the northeast, while individual cases have been confirmed in both North and South Kivu. This is a region scarred by years of armed conflict, which further complicates the movement of medical teams and the delivery of equipment.

Why doesn’t a vaccine help this time?

The core problem lies with the pathogen itself. Unlike earlier waves, which were caused by the Zaire strain, this outbreak involves the rare Bundibugyo strain. Existing vaccines, developed and approved for the Zaire variant, offer no protection against it, so health workers are relying solely on classic measures: isolating the infected, tracing contacts and strict use of protective gear.

This is where the system stumbles most. Contact tracing, which in previous outbreaks reached above 90 percent, has now dropped to just 56 percent. The reasons are resistance from local communities, distrust of the central government and the difficulty of reaching remote villages. Every untraced contact represents a potential new chain of transmission, and with no vaccine available, manually extinguishing each cluster becomes the only line of defence.

The World Health Organization declared the outbreak a public health emergency of international concern back on May 16, opening the way for accelerated mobilisation of funds and experts. The decision carries diplomatic weight too: member states are obliged to report on border measures, and multilateral agencies gain a mandate for coordination that crosses national lines.

What does the outbreak mean for the wider region?

The geographic spread of cases is especially worrying because Ituri and both Kivus border Uganda, Rwanda and South Sudan. Historically, Ebola in eastern Congo rarely stays within one country, and the weakening of contact tracing raises the risk that the disease will cross a border before it is detected. Ugandan authorities have already tightened checks at crossings, while regional health networks exchange data on suspected cases in real time.

For now, no cases have been reported outside Congo, but the combination of a rare strain without a vaccine, a low contact-tracing rate and an unstable security environment creates a scenario in which the figure of 782 cases could easily multiply. The next two to three weeks will show whether the epidemiological response has managed to keep pace with the disease or whether the outbreak will spread to neighbouring provinces.

After the experience of the pandemic, does the world today have enough mechanisms to halt a distant outbreak before it becomes a regional crisis?
