Trust as Public Health Infrastructure: Advancing Health Care Safety Through Risk Communication and Community Engagement

Background Preparedness frameworks traditionally emphasize surveillance, laboratory capacity, clinical care and logistics. However, recent public health emergencies have demonstrated that even technically sound interventions may fail when trust is weak, communication is fragmented or misinformation undermines public confidence. Risk communication and community engagement (RCCE) is therefore increasingly recognized as an important component of effective outbreak response. Perspective Evidence from COVID-19, Ebola and other public health emergencies demonstrates that trust, communication and community engagement influence adherence to public health guidance, vaccine acceptance, healthcare utilization and the implementation of evidence-based interventions. Despite this, RCCE is frequently operationalized as a support function rather than a core response capacity. This perspective argues that RCCE and infodemic management should be recognized as essential public health infrastructure because they create the social conditions necessary for interventions to achieve population-level impact. We discuss practical implications for preparedness planning, performance measurement, workforce development and emergency response systems. Conclusion Preparedness and health care safety frameworks should classify risk communication, community engagement, and infodemic management as core response capacities alongside surveillance, clinical care, and logistics because trust and behavioral uptake determine whether interventions work at the population level.
