Cornell spotlights behavior as a key factor in outbreak spread

Cornell University College of Veterinary Medicine is spotlighting a familiar but still underappreciated outbreak driver: behavior. In a January 9, 2026, Cornell Veterinary Podcast episode, Ana Bento, PhD, an assistant professor in Cornell’s Department of Public and Ecosystem Health, said disease models can miss the mark if they don’t account for how people change their behavior during outbreaks. The episode frames that idea through Bento’s work in quantitative disease ecology and her research on vector-borne diseases such as Zika and dengue, where ecology, movement, contact patterns, and public response all shape transmission risk.

Why it matters: For veterinary professionals, especially those working in public health, shelter medicine, livestock systems, wildlife health, and zoonotic disease response, the message is practical: surveillance and forecasting are only as useful as the assumptions behind them. Cornell has already invested in work to better integrate human behavior, social networks, and real-world decision-making into epidemiological models, with the goal of making those models more useful for policy and outbreak response. That matters in a One Health setting, where pet parent behavior, farm biosecurity practices, wildlife interactions, and public risk perception can all influence whether a disease event stays contained or spreads.

What to watch: Expect more emphasis on behavior-aware surveillance and modeling tools as veterinary, public health, and vector-borne disease programs look for better ways to predict and blunt the next outbreak. (news.cornell.edu)
