Human behaviors driving disease emergence

Area of Science:

• Evolutionary Anthropology
• Disease Ecology
• One Health

Background:

• Zoonotic spillover, the transmission of pathogens from animals to humans, is facilitated by human-animal-environment interactions.
• Current narratives often portray humans as external disruptors of natural disease systems, limiting understanding of human roles.
• Evolutionary anthropology offers a framework to view humans as integral components of disease ecologies.

Purpose of the Study:

• To reframe human drivers of zoonotic disease risk through the lens of evolutionary anthropology.
• To demonstrate how human adaptive strategies in resource acquisition shape high-risk interactions and ecological processes.
• To integrate human ecology and disease ecology theories by examining niche construction and foraging ecology.

Main Methods:

• Literature review synthesizing theories from evolutionary anthropology and disease ecology.
• Conceptual framework development linking human foraging ecology, niche construction, and zoonotic spillover.
• Analysis of how human adaptive strategies influence ecological processes relevant to disease transmission.

Main Results:

• Human adaptive strategies for resource acquisition predictably shape high-risk human-animal interactions.
• Humans actively construct ecological processes that facilitate zoonotic spillover events.
• Contemporary epidemiological risk patterns emerge from the interplay of human foraging ecology and niche construction.

Conclusions:

• Human drivers of disease are rational, adaptive, and dynamic, necessitating their inclusion in disease control strategies.
• Disease control measures should leverage human capacity to influence ecological processes for risk mitigation.
• Viewing humans as functional components of disease ecologies enhances understanding and management of zoonotic risks.
