The coronavirus disease 2019 (COVID-19) pandemic has shown us how important it is to inform key public audiences about impending health risks and strategies for minimizing these risks. Yet, we have learned (the hard way) during the pandemic that serious information dissemination problems can hamper effective responses to major health threats both within and between many countries.The pandemic has provided a vivid example of how communication efforts must be designed and implemented to promote cooperation and coordination among groups of people and between nations to stop the spread of contagion and to mobilize efforts to care for those who become infected. Sadly, there have been multiple communication missteps with efforts to effectively disseminate needed health information to address the pandemic. Ineffective public communication has led to dangerous societal problems such as underestimating the seriousness of the pandemic, spreading dangerous misinformation that led to confusion and errant responses to the pandemic, and failing to provide sufficient rationale to motivate widespread adoption of important prevention, and control guidelines.Addressing large-scale health issues is often tremendously complex for health-care consumers, providers, and others involved in the modern health-care system. Relevant health information is the most valuable resource for health system participants to help them make sense of health complexities and to enable them to make good decisions about how to best address health problems. Yet, contrary to public understanding, competent health communication must involve intricate strategies to match the communication processes to meet the information needs and preferences of different groups of people who often desperately need relevant information to guide their health decisions and actions. This is why research about the dissemination of health information is important for evaluating the
