Addressing historical biases and the limits of biomedical commodities in vector-borne disease control in Africa

---

Résumé

In this essay, we describe efforts to curtail the spread of vector-borne infections and how these efforts are entangled in the causes and consequences of the destruction of life, and the ecosystems which support life, on our planet. Using examples from malaria and sleeping sickness, we show how current efforts to control vector-borne diseases reflect the Western logic of a highly compartmentalized, hierarchical approach, dominated by biomedicine and commoditized interventions. These have dramatically reduced morbidity and mortality yet perpetuate colonial legacies, global inequities, and environmental harm. For instance, billions of insecticide-treated nets, rapid diagnostic tests, and other single-use plastics used in health products generate waste and emissions, while reinforcing fossil-fuel dependence and Global North dominance. These approaches treat diseases as isolated problems detached from the broader socio-ecological system. They excel at suppressing symptoms but leave untouched the root causes such as poverty, ecosystem destruction, and entrenched power imbalances. Current disease research and control strategies are situated within a wider dominant culture that has led to multiple undesirable effects on our planet (including climate, ecological functions, and biosphere integrity) driven largely by wealthy minorities and a global extractive economic system. Our intention is not to promote the idea that communities should be denied commodities that protect against vector-borne disease, but to identify that a shift is urgently required to make space for alternatives. A change involving transdisciplinary, socially-just strategies, that center local leadership, and enforce full life-cycle responsibility for health commodities; all of which are essential to safeguard both human and planetary health.
