Background In recent years, medical journals have emphasized the increasingly critical role that social media plays in the dissemination of public health information and disease prevention guidelines. However, platforms such as Facebook and Twitter continue to pose unique challenges for clinical health care providers and public health officials alike. In order to effectively communicate during public health emergencies, such as the COVID-19 pandemic, it is increasingly critical for health care providers and public health officials to understand how patients gather health-related information on the internet and adjudicate the merits of such information. Objective With that goal in mind, we conducted a survey of 1003 US-based adults to better understand how health consumers have used social media to learn and stay informed about the COVID-19 pandemic, the extent to which they have relied on credible scientific information sources, and how they have gone about fact-checking pandemic-related information. Methods A web-based survey was conducted with a sample that was purchased through an industry-leading market research provider. The results were reported with a 95% confidence level and a margin of error of 3. Participants included 1003 US-based adults (aged ≥18 years). Participants were selected via a stratified quota sampling approach to ensure that the sample was representative of the US population. Balanced quotas were determined (by region of the country) for gender, age, race, and ethnicity. Results The results showed a heavy reliance on social media during the COVID-19 pandemic; more than three-quarters of respondents (762/1003, 76%) reported that they have relied on social media at least “a little,” and 59.2% (594/1003) of respondents indicated that they read information about COVID-19 on social media at least once per week. According to the findings, most social media users (638/1003, 63.6%) were unlikely to fact-check what they see on the internet with a health professional, despite the high levels of mistrust in the accuracy of COVID-19–related information on social media. We also found a greater likelihood of undergoing vaccination among those following more credible scientific sources on social media during the pandemic (χ216=50.790; φ=0.258; P<.001). Conclusions The findings suggest that health professionals will need to be both strategic and proactive when engaging with health consumers on social media if they hope to counteract the deleterious effects of misinformation and disinformation. Effective training, institutional support, and proactive collaboration can help health professionals adapt to the evolving patterns of health information seeking.

Introduction Despite the widespread availability of SARS-CoV-2 vaccines in the USA, vaccine hesitancy continues to represent a significant impediment to the attainment of herd immunity and the end of the COVID-19 pandemic. This survey analysis provides an update for clinical healthcare providers and public health officials regarding current trends in misinformation exposure, as well as common objections to COVID-19 vaccination. Methods We conducted a web-based survey of 600 adults in the state of Florida between June 3 and June 14, 2021. Access to the sample was purchased through an industry-leading market research provider (Prodege MR), and survey respondents were selected using a stratified, quota sampling approach to ensure representativeness. Balanced quotas were determined (by region of the state) for gender, age, race, education, and ethnicity. The survey responses were analyzed using basic descriptive statistics, as well as chi-square testing and a logit regression model. Findings High levels of misinformation exposure were observed among participants, with 73% reporting some exposure to misinformation about COVID-19 vaccines in the past 6 months. Exposure to misinformation was directly correlated with vaccine hesitancy. Among those who did not report any exposure to misinformation, 73.8% of respondents were vaccinated. That number fell to 62.9% with exposure to just one misinformation theme and 52.2% for six or more ( χ 2 = 11.349; φ = 0.138; p ≤ 0.05). Politicization was also found to be a major factor in vaccine hesitancy, with 73.4% of self-identified Democrats being vaccinated, compared to only 58.5% of Republicans and 56.5% of Independents ( χ 2 = 16.334; φ = 0.165; p ≤ 0.001). Both misinformation exposure and political affiliation were strong predictors of vaccination even after accounting for other demographic predictors. Discussion The survey results add to previous research on misinformation and vaccine hesitancy by quantifying exposure to specific misinformation themes and identifying its relationship to vaccine hesitancy. Overcoming these impediments to vaccination will require strategic and targeted messaging on the part of public health professionals, which may be aided by collaboration with political thought leaders. Understanding the volume and nature of misinformation themes the public is exposed to regarding COVID-19 vaccines may aid public health officials in targeting this vaccine messaging to more directly address reasons for vaccine hesitancy.

While emerging technologies such as social media have demonstrated value for crisis communications, significant question remains regarding how these tools can be most effectively leveraged to facilitate the flow of valid information under crisis conditions. In an effort to address these issues, this article examines the use of Twitter during the 2015-2016 Zika virus outbreak in the United States. Particular attention is paid to network structures within the Zika conversation and how different actors and communities contribute to the flow of information throughout the broader Twitter community. Public-facing organizations can benefit from a deeper understanding of the nature and structure of spontaneously occurring communities on social media as well as the types of content that they create and circulate. As such, these findings have significant implications for the development of effective social media strategies during natural disasters and public health emergencies. In particular, this analysis identifies several predominant themes communicated through Zika-related tweets as well as a number of distinct communities and influential actors. The findings suggest that respected political actors, public institutions, as well as those with valid scientific credentials can help to facilitate the flow of accurate and vital information across disparate communities.

The growing influence of social bots in political discussion networks has raised significant concerns, particularly given their potential to adversely impact democratic outcomes. In this study, we report the results of a case study analysis of bot activity in a recent, high-profile political discussion network. Specifically, we examine the prevalence and impact of bots in a Twitter network discussing the Special Counsel investigation into Russian interference in the 2016 U.S. elections. Using this discussion network, we conduct a “before-and-after” analysis to examine the prevalence of social bots in the discussion network as well as their influence on key network features such as (1) network structure, (2) content/messaging, (3) sentiment, and (4) influentialness. Our findings suggest that bots can affect political discussion networks in several significant ways. We found that bot-like accounts created the appearance of a virtual community around far-right political messaging, attenuated the influence of traditional actors (i.e., media personalities, subject matter experts), and influenced network sentiment by amplifying pro-Trump messaging. The results of this analysis add to a growing body of literature on the use and influence of social bots while at the same time uniquely examining their influence in a nonelectoral, political setting.
