Public health communication refers to the process of notifying, educating,
entertaining, and persuading a target audience to be aware of, interested in,
and understand the importance of specific health issues. A two-way
communication is recommended so the target audience has a chance to
gain access and interact with the communication process. Furthermore, the
process must have clear objectives and be planned in such a way that
results can be measured and evaluated (Chansawang 2003).
