Cornell podcast highlights behavior’s role in outbreak spread

Cornell University College of Veterinary Medicine is using its latest podcast to spotlight a core lesson in outbreak science: behavior can reshape the course of disease spread. In “How Behavior Impacts Outbreaks,” published January 9, 2026, Dr. Ana Bento tells host Michelle Moyal that predicting the next pandemic depends not just on pathogens, vectors, or climate, but on how behavior changes during an outbreak. She says that without accounting for the “evolution of behavior,” researchers can’t fully understand or predict epidemic outcomes. (vet.cornell.edu)

That framing fits Bento’s broader research program at Cornell. She is an assistant professor of infectious disease ecology in the Department of Public and Ecosystem Health, where her lab develops theoretical and data-driven models to understand how human and animal systems behave and how those behaviors affect disease transmission. Her listed research areas include adaptive behavior, pathogen evolution, seasonal transmission, anthropogenic effects such as vaccines, and climate, placing her squarely at the intersection of veterinary medicine, ecology, and public health.

The podcast itself is more of an expert explainer than a study release, but it builds on a substantial body of work. Cornell says the episode follows Bento’s path “from chasing crazy sheep to tracking cute monkeys” to tackling the question of when and where the next pandemic will occur. That message aligns with her lab’s stated goal of using mathematical modeling, phylodynamics, and statistical inference to make testable predictions and confront models with real-world data.

Her prior publications help explain why this matters. In a 2022 Nature Communications paper, Bento and colleagues reported that targeted isolation strategies in a coupled epi-economic model could avert up to 91% of economic losses relative to voluntary isolation strategies, without adding disease burden, underscoring how behavioral responses can alter both transmission and the downstream consequences of control measures. She has also contributed to real-time outbreak tracking work, including a 2022 Lancet Infectious Diseases paper on the mpox outbreak. Together, those projects reinforce the idea that disease models become more useful when they incorporate how people actually respond to risk, guidance, and changing outbreak conditions.

Industry reaction to this specific podcast appears limited so far, but Cornell is clearly elevating Bento as a public-facing voice in outbreak science. Her faculty profile notes service on the World Health Organization’s COVID-19 Technical Advisory Group and leadership roles in pandemic prevention and disease ecology networks. Cornell has also recently highlighted her in public health communications, suggesting the college sees her work as part of its broader contribution to preparedness and One Health thinking.

Why it matters: For veterinary professionals, Bento’s message lands well beyond human public health. Disease surveillance in animals, wildlife, and shared human-animal environments is shaped by movement, contact patterns, compliance with control measures, vector exposure, and risk perception, all of which are behavioral variables. That matters in zoonotic preparedness, companion animal and livestock outbreak management, and vector-borne disease planning. Models that treat behavior as static may underperform when veterinary teams need them most: during fast-moving events where pet parent decisions, producer practices, wildlife contact, and public messaging all influence spread.

The podcast also arrives as veterinary medicine continues to lean into One Health and data-enabled forecasting. Cornell’s own public and ecosystem health training emphasizes surveillance, outbreak response, risk communication, and policy change, which matches the operational reality facing veterinary professionals asked to interpret emerging threats across species. Bento’s emphasis on behavior suggests that better forecasting won’t come only from more pathogen data, but from better integration of social, ecological, and veterinary intelligence. That’s a useful takeaway for clinicians, diagnosticians, epidemiologists, and health system leaders alike. (courses.cornell.edu)

What to watch: The next step isn’t likely to be a single policy change, but a continued push toward behavior-aware outbreak models, especially in zoonotic, vector-borne, and cross-sector surveillance systems where veterinary insight can improve early detection and response. (vet.cornell.edu)
