Which strategy can help increase engagement during a public health campaign?

Interactive formats like social media contests and challenges are effective strategies for increasing engagement during a public health campaign because they actively involve the audience in the campaign's messaging and activities. Engaging the audience through interactive elements fosters a sense of community and encourages participation, making individuals feel like they are part of the campaign rather than just passive recipients of information.

When people participate in contests or challenges, they are more likely to share their experiences and results, which can expand the reach of the campaign through organic sharing. This method creates a dynamic environment where the audience can communicate, respond, and reflect on their understanding of the health messages being conveyed. Additionally, using platforms that people are already familiar with, such as social media, can make the content more relatable and accessible, leading to improved engagement and retention of the campaign's objectives.
