Overview
A study from the University of California San Diego suggests that behavioral shifts triggered by disease threats are not unique to human populations. Following an encounter with a viral outbreak, certain non-human primates also demonstrate increased caution regarding germs.
Research Context
During the initial stages of the COVID-19 pandemic, human households exhibited heightened preventative measures against pathogen transmission amid limited information about how the virus spread. These responses included sanitizing groceries prior to storage, coping with shortages of hand sanitizer, and exercising heightened caution regarding germs carried by other people. The study contextualizes these reactions to evaluate whether post-outbreak caution exists across other primate species.
Findings
The University of California San Diego findings suggest that behavioral adaptation to pathogen exposure is not limited to humans. In the wake of a viral outbreak, some primates similarly adjust their actions and exhibit caution toward germs.
Why This Matters
The observation indicates that behavioral changes following an infectious disease threat are shared across primate species, showing that heightened caution toward germs in the aftermath of an outbreak is not an exclusively human response.
