New undiagnosed disease in DR Congo: urgent action needed - Lancet
The outbreak of an undiagnosed disease in DR Congo, reported by WHO on Dec 8, 2024,1 is a pressing global health concern that demands swift and coordinated action. As of Dec 5, 406 cases and 31 deaths have been reported in the Panzi health zone in Kwango province, with influenza-like symptoms and anaemia. Most affected individuals are children aged younger than 5 years, many of whom are severely malnourished.
The remoteness of the region and poor infrastructure complicate the identification of the pathogen, with suspicions that multiple diseases could be contributing to these cases. Furthermore, the outbreak has the potential to transcend regional boundaries, particularly as DR Congo shares porous borders with Angola, where provinces such as Uige are vulnerable to cross-border transmission. Mobility between these regions could facilitate the spread of the disease to neighbouring African countries, raising the potential for a Public Health Emergency of International Concern.
With disease samples dispatched to Kinshasa for laboratory testing to determine the pathogen's origin, we are in a crucial window to prevent its further spread. Today, the approach must be different. The disease's unknown nature warrants containment measures at both the local and international levels. These measures should include the immediate restriction of cross-border movement in affected regions, enhanced disease surveillance, and the rapid mobilisation of health-care resources to DR Congo and neighbouring countries. Additionally, the international community must recognise that this is not solely an African challenge; it is a global health threat. Comprehensive funding and logistical support should be prioritised, enabling rapid diagnostic efforts, contact tracing, and the provision of personal protective equipment to front-line workers.
The risk of spillover into neighbouring countries underscores the urgency for Angola and other countries in the region to heighten preparedness measures. These measures should include deploying rapid response teams, establishing quarantine protocols, and intensifying public health communication to mitigate panic and misinformation. In this interconnected world, a delayed or fragmented response could allow this disease to evolve into a global health crisis. By learning from our recent past, we can change the trajectory of this outbreak and safeguard lives across continents. The experience with COVID-19 has shown that delays in responding to outbreaks can have catastrophic consequences. Therefore, it is imperative that the global community acts decisively to contain this undiagnosed disease in DR Congo, protecting not only African populations, but also global public health.
