Which type of public health communication has other public health experts as the audience?

The correct choice is a scientific poster presentation. This type of communication is specifically designed for sharing research findings and public health information among professionals and experts in the field. At conferences or academic settings, a scientific poster presentation allows researchers to convey complex data, methodology, and results to an audience that is knowledgeable about public health concepts and terminology.

In contrast, a community workshop, radio interview, and informational brochure are aimed at the general public or specific community groups. These formats are tailored to provide information in a more accessible way to individuals who may not have a formal background in public health, focusing on practical implications, awareness, or community engagement. Thus, the scientific poster presentation is uniquely suited for an audience of public health experts, facilitating in-depth discussions and professional feedback.
