Background. Primary health care (PHC) in Indonesia plays an important role in combating the spread of COVID-19 in the community. While each PHC deals with different situations at the beginning of COVID-19, the purpose of this study is to investigate the roles of PHC in preventing COVID-19 spread and promoting healthy behavior in the community. Methods. Applying qualitative approach, this study collected data through focus group discussions and then analyzed the data using a thematic content analysis. PHC health officers from eight Indonesian regions, ranging from western to eastern Indonesia, took part in this study. Results. This study found that PHCs play crucial roles in preventing the spread of COVID-19 and promoting healthy behavior. They collaborated with the community to identify suspected COVID-19 cases, provided isolation facilities, and educate the public about COVID-19 prevention. The community contribution was somehow followed by stigmatization of COVID-19 patients, complicating PHC efforts to prevent COVID-19 spread. Using WHO building blocks, we identified lacking in leadership, health workforce, and access to essential medicine as another challenge for PHC to perform their tasks. Conclusion. PHC must employ strategies to provide comprehensive understanding and combat stigma associated with COVID-19 since community plays pivotal roles and presents hurdles in preventing the spread of COVID-19.
