Reducing the threats of rodent-borne zoonoses requires an understanding and leveraging of three key pillars: disease ecology, synanthropy, and rodentation.

Abstract

Rodents have co-existed with humans for centuries, and frequently exchange pathogens. Historically, rodent-driven plague outbreaks scoured the Old World, resulting in substantial human mortality. Although such pandemics have not occurred for centuries, serious threats from rodent-borne infections, such as the global emergence of mpox, still exist. Moreover, endemic and emerging rodent infections continue to cause substantial human morbidity and mortality in low-income and middle-income countries. Efforts by the medical community to control rodent-borne zoonoses primarily focus on treating or preventing symptoms in humans using biomedical interventions (eg, vaccination). Such approaches are geared towards preparedness and response but are insufficient for prevention. In this Personal View, we identify three key pillars that drive rodent-borne zoonotic spillover: ecology of rodent infections; use of human habitation by rodents (synanthropy); and the influence of humans on the ecological proliferation of rodents in our landscape (rodentation). The challenge is to leverage these pillars as entry points for interventions, to prevent spillover and reduce disease burden. Given shortcomings of rodent culling, we advocate for integrated countermeasures that are socially and ecologically grounded, apply systems thinking, and leverage emerging technologies to prevent spillover driven by persistent human-rodent interactions and global change.
