A new Ebola outbreak has been declared in the Democratic Republic of Congo’s Kasai province.
The Democratic Republic of the Congo (DRC) is once again on high alert following the declaration of a new Ebola outbreak in the remote Kasai Province.
This marks the 16th time the country has faced the deadly virus since its discovery nearly five decades ago.
The outbreak, which was officially declared in early September, is raising serious concerns due to its location in a hard-to-reach area near the border of Angola.
The current outbreak is caused by the Zaire Ebola virus, the most severe strain of the disease. The first known case was a 34-year-old pregnant woman who died in late August.
Since then, the virus has spread to her contacts, including two healthcare workers who treated her and have also succumbed to the disease.
As of mid-September, the Africa Centres for Disease Control and Prevention (Africa CDC) reported dozens of confirmed cases and a growing number of deaths, highlighting the rapid and dangerous nature of this new cluster.
A Different Kind of Outbreak: Spillover from Nature
Unlike some previous outbreaks that were a resurgence of a dormant strain in a survivor, genetic analysis suggests this one is a new zoonotic spillover.
This means the virus likely jumped from an animal host, such as a fruit bat or monkey, to a human, reigniting the chain of transmission. This finding underscores the ongoing risk of Ebola and other hemorrhagic fevers in regions where humans and wildlife coexist.
The epicentre of the outbreak is the Bulape Health Zone, a rural area with limited infrastructure. This presents a dual challenge: it can make it harder for the virus to spread to major urban centres but also creates significant logistical hurdles for health responders trying to get supplies and personnel into the affected region.
The proximity to the provincial capital of Tshikapa city and the border with Angola also poses a risk of wider regional spread if not quickly contained.
The Response: A Race Against Time
A swift and coordinated response is underway from the DRC government, the World Health Organization (WHO), and other international partners like Médecins Sans Frontières (MSF) and the Africa CDC. Key pillars of the response include:
- Vaccination: Front-line health workers and contacts of confirmed cases are receiving the Ervebo vaccine, which has proven highly effective against the Zaire strain. The WHO has already begun dispatching thousands of doses to the affected area.
- Contact Tracing: Teams on the ground are working tirelessly to identify and monitor anyone who may have come into contact with confirmed cases. This “ring vaccination” approach is critical to stopping the spread.
- Community Engagement: Health officials are working with local communities to raise awareness about safe practices, including hygienic burial rituals, which are a major source of transmission in many outbreaks.
- Medical Care: The establishment of Ebola treatment centres and the provision of supportive care, including rehydration and therapeutic drugs, are essential for saving lives.
Despite these efforts, challenges remain. A major hurdle is the lack of infrastructure, including passable roads and reliable cold chains for vaccines.
The DRC is also battling other public health crises, including a large mpox epidemic and outbreaks of cholera and measles, which stretch already strained resources.
While the WHO has assessed the risk as high for the DRC, it remains moderate for the region and low globally.
The hope is that with early detection and the availability of a proven vaccine, this latest outbreak can be contained and brought to an end quickly, preventing another major crisis.
