ABSTRACT

After remarkable success from 2000 to 2015, the progress in reducing the global malaria burden has stalled and even reversed in the last few years according to the World Health Organization. Vector control is currently the single most powerful intervention against malaria, but there is evidence that elimination is not feasible with the available vector controls tools in most settings. As there are ongoing global efforts to develop and test novel methods, zooprophylaxis refers to the use of livestock to divert mosquito vectors away from humans, potentially reducing malaria transmission. However, conflicting evidence highlights the concept of zoopotentiation, where livestock may instead increase vector populations and enhance malaria transmission. This controversy raises ongoing debates about the role of cattle in malaria. Here, we implemented a novel spatial approach to explore the role of cattle on malaria transmission in coastal Kenya. Using data with high granularity from a recent clinical trial, we explore variables beyond ownership. We show that the cattle-to-human ratio measured at 400 and at 500 meters around the household is significantly related to higher odds of testing positive for malaria. Cattle kept within 200 m of households do not impact malaria prevalence. Furthermore, we demonstrate that livestock can and should be considered a contributing environmental factor in malaria transmission and not only a family asset.
