Mystery Disease in the Democratic Republic of Congo Sparks Investigation

A deadly outbreak of an unknown disease has struck the southwestern Democratic Republic of Congo (DRC), claiming between 67 and 143 lives in just two weeks. Health officials report that the disease causes flu-like symptoms, including fever, headache, cough, and anaemia. Women and children are reported to be the most seriously affected, according to an epidemiologist speaking to Reuters.
Local health authorities are working urgently to identify the cause of the outbreak. Initial investigations are focusing on diseases endemic to the region, such as malaria, dengue fever, or chikungunya. However, officials face significant hurdles due to limited diagnostic testing facilities and infrastructure challenges.
Sample collection, transportation, and testing remain difficult in the DRC. Many local clinical laboratories can only test for common pathogens, with limited capacity for identifying rarer infections. In cases requiring advanced diagnostics such as gene sequencing, samples must often be sent abroad. However, international sharing of biological samples is controversial, with concerns about equitable access to the resulting benefits.
Determining the full extent of the outbreak is another priority. Remote regions in the DRC often lack adequate healthcare facilities, with fewer than two doctors per 10,000 residents. By comparison, the United Kingdom has more than 31 doctors per 10,000 residents.
Not all infected individuals seek medical care, especially in areas with few clinics. Even among those who do, not all cases are tested or reported. This underreporting complicates efforts to gauge the true scale and severity of the outbreak.
The outbreak is part of a broader pattern of emerging infectious diseases, driven by factors such as climate change, urbanisation, deforestation, and population growth. These conditions increase the likelihood of infections jumping from animals to humans, a phenomenon known as “spillover”.
Disease surveillance in the DRC, as in many low-income countries, is underfunded and fragmented. Reporting delays between infection, diagnosis, and notification slow response times. A lack of standardised processes, trained personnel, and sufficient resources compounds the problem.
Globally, disease surveillance systems are also fragmented, leaving many areas vulnerable to undetected outbreaks. The consequences are particularly severe in resource-poor regions such as sub-Saharan Africa.
The World Health Organization (WHO) has launched several initiatives to improve outbreak responses. One such programme, the 7-1-7 initiative, sets targets for outbreaks to be detected within seven days, reported to public health authorities within one day, and an initial response launched within seven days. While this approach is promising, it may still be too slow for fast-spreading diseases.
Another WHO effort, the Integrated Disease Surveillance and Response (IDSR) programme, has been active in Africa for two decades. Despite its potential, progress has been hindered by financial constraints, workforce shortages, and data-sharing difficulties.
More recently, the WHO has promoted the International Pathogen Surveillance Network, which aims to improve collaboration across sectors such as human health, animal health, and environmental monitoring. These efforts encourage sharing of expertise and data to create a more cohesive response system.
This outbreak highlights the urgent need for stronger global disease surveillance and rapid response mechanisms. Without significant investment in these areas, there is a risk that future pandemics will remain undetected until it is too late. Improved coordination, better infrastructure, and equitable international collaboration are crucial for mitigating the impact of such crises.
