Ebola Spreading at Unprecedented Rate, Driven by Different Strain and Reduced Aid

The Ebola virus is spreading at an unprecedented rate this year, with the current outbreak in the Democratic Republic of Congo (DRC) surpassing the speed of previous epidemics. In the first five months since the outbreak began, the World Health Organization (WHO) has reported 9,415 confirmed cases and 4,536 deaths within the DRC. While the virus has largely remained contained within the DRC's borders, case counts in neighboring Kenya and Uganda are also increasing, with 20 confirmed cases in Uganda and eight in Kenya.

The speed of the current outbreak far exceeds that of the 2014 West African epidemic. Approximately 150 days after its declaration, the 2014 outbreak had reported 2,599 cases, whereas the current outbreak reached 8,978 cases by the same point and continues to climb.

Viral Strain and Medical Solutions

A primary reason for the rapid spread is that the current epidemic is caused by a different viral strain, known as Bundibugyo. While it belongs to the same viral family as those responsible for the 2014 West Africa and 2018 Congo epidemics, the Bundibugyo strain is distinct enough that existing medical solutions are not as effective. Unlike the Zaire virus, for which vaccines and treatments were developed, there is currently no vaccine for Bundibugyo.

This is not the first encounter with the Bundibugyo strain. Previous outbreaks occurred in Uganda in 2007 and in Congo's eastern province in 2012. Those outbreaks were contained within months through efforts by the country's Ministry of Health and international partners like the WHO, the US Agency for International Development (USAID), and humanitarian organizations such as UNICEF and the Red Cross.

Impact of Reduced Aid and Internal Conflict

However, efforts to curb the spread have been significantly hampered by reduced USAID funding in recent years. Tracing requires substantial resources, including testing capacity, health workers, and protective equipment for those treating suspected cases. With strains like Bundibugyo, where no effective vaccine exists, contact tracing and isolation are critical, making access to these resources particularly vital.

Cuts to aid for disease surveillance created a "critical four-week detection gap between the onset of symptoms of the presumed index case…and the laboratory confirmation of the outbreak," according to a WHO situation report. In August, the United States pledged an additional $242 million to its initial $23 million pledge made in May, aiming to address some of these resource deficits.

The DRC faces additional challenges due to ongoing internal conflict and a humanitarian crisis in its eastern provinces. Years of conflict have weakened public infrastructure, including the healthcare system. This has left a significant portion of the population vulnerable to disease, with nearly 25 percent facing food insecurity and 4.5 million children suffering from clinical malnutrition. Violence has also displaced millions and disrupted public health responses, exacerbated by widespread mistrust in health authorities.
