An “infodemic” describes the rapid spread of large amounts of sometimes conflicting or inaccurate information that can impede the ability of individuals, communities, and authorities to protect health and effectively respond in a crisis.1 Even a deluge of accurate information can overwhelm the public.
In times of emergency, people do not always have access to the information they need. The COVID-19 pandemic incited an unprecedented infodemic highlighting the impact of misinformation, disinformation, and information disseminated with malicious intent on the effectiveness of public health action and national health security.
At the request of the Centers for Disease Control and Prevention (CDC), the National Academies of Sciences, Engineering, and Medicine hosted a two-day public workshop on April 10-11, 2023 to examine the history of public health infodemics, the impact of infodemics on trust in the public health enterprise, and tools and practices used to address infodemics.

[1] The workshop planning committee devised its own definition of "infodemic" to steer the workshop planning process and to contextualize the term within the workshop's scope, while also acknowledging other pre-existing definitions and their utility.
The first session began with remarks from Nancy Tomes, Stony Brook University, who described the history of infodemics, noting their occurrence during the 1918-1919 influenza pandemic, the 1980s HIV/AIDS pandemic, and the 2003 severe acute respiratory syndrome outbreak. Tina Purnat, World Health Organization, explained how the speed and scale of infodemics now exceed the current capacities of health information technologies and underfunded health systems. Dietram A. Scheufele, University of Wisconsin-Madison, described the effects of an amalgam of science, policy, and partisan politics on declining trust in science. Umair Shah, Washington State Department of Health, discussed rumors that affected behavior during the responses to Hurricanes Katrina in 2005 and Harvey in 2017, as well as rumors that fueled discrimination against Asian Americans during the COVID-19 pandemic.
Tara Kirk Sell, Johns Hopkins Bloomberg School of Public Health, stressed that a constellation of interventions is needed to effectively meet the diverse needs of various communities and populations in addressing infodemics. Annie Sundelson, Johns Hopkins Bloomberg School of Public Health, outlined a set of approaches that can be used to help manage infodemics. Sandra Quinn, University of Maryland, provided an overview of the Building Public Trust in Public Health Emergency Preparedness and Response (PHEPR) Science workshop held in 2022.
Maddie Perlman-Gabel, New York City Department of Health and Mental Hygiene, described the work of the department’s Misinformation Unit that was established in March 2021 to identify factors undermining COVID-19 vaccine confidence. Phil Maytubby, Oklahoma City County Health Department (OCCHD), shared how OCCHD used sentiment analysis surveys to inform their COVID-19 vaccination campaign messaging community. Scott Burris, Temple University, discussed how public health law can be leveraged to address infodemics. Ian Brooks, University of Illinois Urbana-Champaign, discussed how the Pan American Health Organization/WHO Anti-Infodemic Virtual Center for the Americas (AIVCA) has established international, multidisciplinary teams to detect, research, prioritize, and respond to misinformation threats.
Lisa Cox, Missouri Department of Health and Senior Services, described how public health officials leveraged preexisting relationships to reach certain communities and engaged with trusted messengers to connect with other hard-to-reach communities. Monica Schoch-Spana, Johns Hopkins Bloomberg School of Public Health, explained how community-based participatory research techniques can reveal nuanced values and priorities within vulnerable groups. Teresa Wagner, The University of North Texas Health Science Center at Fort Worth, highlighted support for health literacy as an approach to counteracting harm from infodemics. Highlighting the importance of cultural context and meeting community members where they are, Amanda Boyd, Washington State University, explored infodemic preparedness and response efforts within Indigenous communities.
Kate Starbird, University of Washington, explored a framework for and the benefits of shifting the terminology around infodemics, specifically the term “rumor.” Neil Johnson, The George Washington University, showed how mapping the ecosystem of online communities can predict the potential spread of misinformation. Alejandro Posada, Internews, discussed how social listening can used to synthesize public discourse into insights about a particular community. Christopher Voegeli, CDC, highlighted the State of Vaccine Confidence Insights Report series, in which CDC provides iterative and inductive analyses of misinformation, tracks themes, and issues recommendations. Rachael Piltch-Loeb, Harvard T.H. Chan School of Public Health, described psychological inoculation, or “pre-bunking,” a communication technique that builds psychological resistance against a future persuasion strategy.
During the concluding roundtable discussion, panelists identified practices, capacities, capabilities, partnerships, and collaborations that could be developed within the next decade to address infodemics. William Hallman, Rutgers Global Health Institute, discussed the integration of effective communication strategies into every aspect and every level of public health. Demetre Daskalakis, White House National Mpox Response, reflected on the U.S. mpox experience and lessons learned for risk communications. Michael Fraser, Association of State and Territorial Health Officials, underscored how community engagement efforts should be at the forefront of infodemic response strategies. Jewel Mullen, University of Texas at Austin, remarked on the impact of community health works and their role during an infodemic. Bruce Y. Lee, City University of New York, shared a systems perspective on how to confront future infodemics.
