Public understanding of respiratory virus transmission and prevention is shaped by a wide range of information sources, including social media. As social media platforms play an increasingly central role in shaping health communication, it is critically important to define best practices to disseminate reliable information online. This is especially important when considering the lives of susceptible groups who may not have easy access to culturally relevant and language-concordant reputable sources. Although access to health care remains a significant barrier, access to reliable health messaging is a significant predictor of immunization against respiratory viruses. Yet, little is known about community-level differences in how narratives about respiratory virus protection emerge, how they are shared, and how they ultimately affect decision-making in favor of proven infection prevention strategies. Social media posts that include personal narratives are effective at reliably communicating health recommendations, especially those that come from a trusted peer. Therefore, communication strategies that leverage neighborhood and interpersonal relationships can prove extremely effective at health communication. Community health workers are trusted community members who serve as links between health/social services and a defined region to improve access to health services and quality of service delivery. Community health workers can diffuse reliable information in the neighborhoods they serve and can be essential to address concerns about health recommendations, increase trust, and improve health outcomes; they have been at the forefront of addressing lower rates of testing for respiratory viruses and inform decision-making to promote evidence-based immunization practices in communities with unmet health and social needs. Community health workers are uniquely positioned as trusted messengers to disseminate reliable information through strategic use of social media and principles of health communication. Dime La Verdad (Tell me the truth) is an innovative social media capacity-building program based on theoretical frameworks related to health communication that empowers community health workers to disseminate reliable information about respiratory virus protection strategies through the use of personal narratives on social media. The proposed work will use a rigorous stepped wedge design to 1) deliver a scalable program of science communicators using an adapted curriculum grounded in principles of health communication, 2) evaluate how diffusion of health messaging is perceived on social media, and 3) discern how use of personal narratives to enhance science communication can encourage informed decision-making to promote evidence-based immunization practices and improve health outcomes.
