This qualitatively study used a sample of 30 communication experts and health professionals to explore the role of social media in mitigating COVID-19 infections and its implications to people's health in Zanzibar. The findings revealed that social media are powerful platforms in providing health awareness information for mitigating COVID-19 and these platforms have enabled people to understand local medicines used to reduce the COVID-19 infections. In addition, there is high connection between online health information and offline people's health actions.
