Public health communication is an interdisciplinary field of research and practice dedicated to the strategic use of communication processes, channels, and messages. It investigates the development, dissemination, and impact of health-related information and persuasive strategies aimed at informing, influencing, and empowering individuals, communities, and policymakers to promote health, prevent disease, and improve health outcomes at various levels. Its significance lies in its capacity to translate health knowledge into actionable behaviors, shape social norms, advocate for supportive policies, and build capacity for health improvement.
