Background: The COVID-19 pandemic has highlighted the critical role of public participation in disease control. Understanding the components of this participation is crucial for effective management of future pandemics. This study aimed to identify the key elements of people's engagement in COVID-19 control efforts. Methods: This content analysis (qualitative study) was conducted using semi-structured interviews with 12 experts (medical, media/communication) and 10 community members. Thematic analysis was employed to identify primary codes, subcategories, and categories within the interview data. Results: Analysis revealed 1012 initial codes. After refinement and categorization, 200 codes were organized into 21 subcategories, 9 categories, and ultimately, 3 core themes: 1) Role of the Media, 2) Public Participation, and 3) COVID-19 Control. The "Role of the Media" theme comprised three subthemes: trust in media, interactive vs. non-interactive media. The "Public Participation" theme encompassed social participation, therapeutic participation, and the role of media in facilitating participation. Finally, the "COVID-19 Control" theme included three subthemes: public knowledge, psychological burden of the disease, and the media's influence on control efforts. Conclusion: This study identifies key components of public participation in COVID-19 control. By focusing on these elements and strengthening media efficacy, we can enhance preparedness for future pandemics.
