Public Perception and Behavioral Response to Infectious Disease Pandemics
Summary
The public’s perceptions of infectious threats and their consequent behaviours are central to the trajectory of epidemics and pandemics. Research has shown that both cognitive assessments of risk—such as perceived susceptibility and perceived severity—and affective responses—such as anxiety and worry—drive adoption of protective measures. Non-pharmaceutical interventions, including hand hygiene, mask-wearing and social distancing, often rely on public compliance in the absence of immediate pharmaceutical solutions. Theoretical frameworks such as protection motivation theory elucidate how self-efficacy, outcome expectancies and threat appraisal interact to shape individual and collective responses. Socio-demographic factors, including age, gender and cultural context, modulate these responses, while trust in authorities and clarity of communication determine the effectiveness of public health campaigns. Over time, perceptions and behaviours evolve in response to changing epidemiological data, media narratives and personal experience, highlighting the need for adaptive messaging and inclusive engagement. Effective understanding of these dynamics has global significance, informing policy design, communication strategies and model parameterisation to stem disease spread and mitigate social disruption.

Technical terms
Risk perception: An individual’s cognitive evaluation of the likelihood and severity of contracting an infectious disease.
Protective behaviour: Actions taken to reduce the probability of infection, including non-pharmaceutical and pharmaceutical measures.
Non-pharmaceutical intervention (NPI): A strategy to limit disease spread without medical treatment, such as social distancing or hand hygiene.
Self-efficacy: Confidence in one’s ability to perform recommended protective actions.
Perceived severity: Individual assessment of the serious health consequences of infection.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
