This survey underscores a crucial dynamic in the current health communication landscape: while individuals predominantly rely on their healthcare providers for credible information, there is a conspicuous and robust trust in professional health and scientific bodies that adhere to rigorous evidence-based standards. The American Heart Association, with its century-long legacy of advancing cardiovascular and cerebrovascular health, clearly occupies a central role in this network of trusted institutions.

The APPC study involved a nationally representative sample of 1,650 adults and was conducted amid a complex ecosystem of health information dissemination characterized by the proliferation of misinformation and disinformation. It highlights Americans’ discernment in differentiating between advice from personal clinicians, career scientists at U.S. health agencies, and organizational leaders, with the former two categories receiving substantially higher confidence ratings.

Nancy Brown, CEO of the American Heart Association, interprets the findings as a testament to the Association’s unrelenting commitment to scientific rigor, transparency, and integrity. She emphasizes that maintaining public trust in an era saturated with conflicting health narratives necessitates ongoing diligence and adherence to the highest standards of evidence. The AHA’s multidisciplinary volunteers, professional staff, community advocates, and philanthropic partners collectively underpin this formidable trust.

For over 100 years, the AHA has been at the forefront of research and guideline development relating to the prevention, diagnosis, and treatment of cardiovascular diseases and stroke. Its capacity to convert complex scientific findings into actionable, understandable, and trustworthy guidance has positioned it as a critical instrument in public health. This expertise and careful stewardship are vital in combating the increasing tide of health misinformation that challenges public understanding and decision-making.

The broader implications of the APPC’s findings are significant for the entire public health communication field. In an information environment that is not only crowded but often polarized and fragmented, the role of independent, science-driven organizations in mediating trustworthy health guidance becomes indispensable. The public’s alignment with such entities suggests a foundation upon which credible health promotion initiatives can be reliably built.

From a technical standpoint, the methodology of this survey leveraged robust sampling techniques to ensure representation across multiple demographic strata, enhancing the reliability and applicability of its conclusions. The margin of error, approximately 3.5 percentage points, affords a high confidence level in the accuracy of the reported trust metrics. Notably, the American Heart Association had no influence on the poll design or data analysis, affirming the independence and objectivity of the findings.

These revelations emerge in parallel with a growing scientific emphasis on transparency in public health messaging, especially amid the COVID-19 pandemic and other ongoing health crises. The clear delineation between trusted clinical sources and health agencies reflects the importance of evidence-based policy originally evolved through such institutions—a dynamic vividly captured by this APPC survey.

The American Heart Association’s enduring relevance is further reinforced through its dynamic approach to integrating science, policy advocacy, and grassroots engagement. The synergy of these elements helps combat health disparities and promotes equitable health outcomes, responding to the pressing needs of diverse communities, including those disproportionately affected by cardiovascular diseases.

Further, the findings shed light on the psychological underpinnings of public trust. Trust is not merely a function of information accessibility but the perceived integrity, competence, and values alignment of information sources. The AHA’s engagement in continuous scientific scrutiny and open communication likely fosters these attributes, promoting resilience in public trust compared to fragmented or politically influenced information sources.

This landscape also emphasizes how professional health organizations can play a pivotal role in the ecosystem of health literacy, empowering individuals to make informed decisions amidst competing narratives. By maintaining an unwavering foundation in scientific evidence, such bodies provide a counterbalance to misinformation, helping to stabilize public health behaviors and outcomes.

The APPC results invite a reconsideration of how public health information is disseminated and consumed in the digital age. As new technological platforms proliferate, the centrality of trusted, evidence-driven organizations like the American Heart Association becomes more necessary than ever, requiring innovative communication strategies to sustain and expand public confidence.

In sum, the Annenberg Public Policy Center’s 2026 survey paints a compelling portrait of public trust in health information sources within the U.S., highlighting the American Heart Association’s distinguished position immediately following personal physicians. It underscores the critical importance of transparency, scientific rigor, and integrity in health communication and serves as a call to action for all health organizations to uphold these principles in the face of challenges posed by misinformation and evolving public health demands.

Alpha-gal syndrome (AGS), an increasingly recognized allergic condition triggered by tick bites, particularly from the Lone Star tick, results in hypersensitivity to galactose-α-1,3-galactose—a carbohydrate found in red meat and other non-primate mammalian products. Patients with AGS often face sudden, severe allergic reactions, complicating diagnosis and management. Given the relative novelty and complexity of this condition, many affected individuals turn to social media platforms seeking information, support, and advice. Recognizing this trend, Dr. Nadia Hamid and colleagues conducted a qualitative analysis of the top 100 English-language videos hashtagged with “#alphagal” on a popular video-sharing platform, scrutinizing the sources, content accuracy, and engagement metrics of these posts.

This thorough content analysis revealed that out of 5,572 videos tagged with variations of alpha-gal, only a fraction—15 videos—were authored by physicians, and notably, over half of these health professional contributors were not allergists. Despite their scarcity, videos created by physicians garnered significantly higher engagement, averaging more than 31,000 likes and 830 comments, compared to approximately 9,200 likes and 202 comments for non-physician videos. Physician videos tended to be longer and more detailed, averaging 2 minutes and 32 seconds, offering viewers a richer, more informative experience. The non-physician content was often anecdotal, brief, and lacked medical rigor, highlighting a critical gap in authoritative information dissemination.

Physicians contributing content spanned a range of specialties beyond allergy and immunology, including gastroenterology, cardiology, orthopedic surgery, family medicine, emergency medicine, pediatrics, and psychiatry. This interdisciplinary presence suggests a broad recognition of the systemic impacts AGS may have. However, the relative underrepresentation of allergists—experts best equipped to diagnose and treat such immunologic disorders—indicates an opportunity for increased specialist engagement. Dr. Hamid emphasized that while personal narratives provide comfort and foster community among patients, without robust input from allergists, misinformation may spread unchecked, impeding effective public health education about AGS.

Parallel to this investigation, another study led by Dr. Ishitha Jagadish explored the proliferation of misinformation about asthma on TikTok, one of the fastest-growing platforms for health content, especially among younger demographics. Asthma, a chronic inflammatory disorder of the airways affecting millions globally, requires ongoing management and evidence-based interventions. Misconceptions about its treatment and prognosis are not only common but can be potentially dangerous if patients forsake medical advice for unproven remedies widely circulated on social media.

The TikTok study analyzed the 40 most-liked English-language videos posted in 2024 under the hashtag “#asthma.” Strikingly, over 25% of these high-visibility videos contained inaccurate or misleading information. Key myths promulgated included assertions that asthma can be completely cured through breathing exercises alone and warnings that combining caffeine with asthma inhalers could be fatal—claims that lack scientific support and could misguide vulnerable individuals. These misleading videos enjoyed more than three times the median likes of their accurate counterparts, indicating the troubling virality of misinformation.

Despite the abundance of anecdotal and user-generated content, only 22% of highly-viewed asthma videos were created by physicians, with the majority 78% coming from non-physician creators. The objectively measured quality of videos, assessed via the Global Quality Score and a modified DISCERN tool designed to evaluate the reliability of health information, was generally low, reflecting deficiencies in both accuracy and comprehensiveness. The low interrater reliability scores in assessment also highlight challenges in uniformly classifying content quality on rapidly evolving social media platforms.

Both studies exemplify the broader tensions within digital health communication: while patient stories and peer-shared experiences can build empathy and solidarity, unchecked misinformation may lead to adverse health behaviors and outcomes. The engaging nature of viral content—often concise, sensationalized, or emotive—can eclipse more nuanced, medically accurate messages. This phenomenon underscores the urgent need for allergists and asthma specialists to amplify their presence online, crafting content that is both scientifically sound and relatable to diverse audiences.

Social media platforms such as TikTok and others offer unprecedented opportunities for timely, widespread dissemination of accurate medical knowledge. The challenge lies in harnessing this potential strategically to counteract the magnetism of misleading content without alienating patient communities that value authenticity and shared experience. Innovating communication approaches to blend clinical expertise with engaging storytelling could bridge this gap effectively.

Furthermore, the studies suggest that collaboration among multidisciplinary teams—including allergists, primary care providers, and specialists from other fields—could enhance content diversity and reliability. Encouraging credential verification, transparency about authorship, and adaptive multimedia strategies may also aid in elevating the standard of health information circulated online. These measures can empower patients to make well-informed decisions about their health, mitigating the risks posed by viral misinformation.

The evolving landscape of digital health education demands proactive involvement from experts who can guide public discourse. By engaging with patients on their preferred platforms and presenting evidence-based content in dynamic, accessible formats, healthcare professionals can reclaim their authority and trust in the social media arena. This proactive approach is essential not only for conditions like alpha-gal syndrome and asthma but also for a broad spectrum of health issues vulnerable to misinformation epidemics.

As digital engagement grows, continued research into the patterns and impacts of online medical information will be instrumental in shaping effective public health interventions. These seminal studies presented at the 2025 ACAAI Annual Scientific Meeting provide valuable insights and a clarion call for the allergy and immunology community to deepen its commitment to digital health literacy. The ultimate goal remains clear: to transform social media from a double-edged sword into a powerful weapon against misinformation and a beacon for accurate, compassionate patient education.

The three-day camp, held from July 23 to 25, 2025, convened fourteen students from grades 9 through 12 to engage with an array of expert virologists, epidemiologists, clinicians, and public health officials. Through hands-on laboratory sessions, simulated outbreak investigations, and critical analysis of media misinformation, the participants were introduced to not only the biological mechanisms underpinning viral transmission but also the socio-political complexities surrounding pandemic response strategies. By combining rigorous science education with practical exposure, the program emphasized an integrative approach to pandemic preparedness.

Central to the educational framework was direct interaction with internationally renowned experts, including Dr. Robert C. Gallo, MD, co-founder of the GVN and a luminary in viral oncology and epidemiology. Dr. Gallo shared his pioneering insights on virus discovery—highlighting his seminal work in identifying HIV as the causative agent of AIDS—and underscored the imperative of cultivating scientific integrity amid the rampant misinformation that challenges public health efforts today. His discussions resonated strongly with the students, reinforcing the ethical responsibilities accompanying scientific inquiry.

The camp’s curriculum was meticulously crafted to offer experiential learning opportunities that bridge theoretical knowledge with applied science. Students toured advanced research laboratories such as the USF Center for Global Health and Inter-Disciplinary Research, the Florida Department of Health Bureau of Public Health Laboratories, and the Hillsborough County Health Department. These visits exposed students to cutting-edge diagnostic technologies, molecular virology techniques, and public health surveillance systems crucial for real-time outbreak detection and response.

One highlight of the program was the immersive laboratory exercises conducted in mock Biosafety Level 3 (BSL-3) facilities. Here, students donned personal protective equipment and simulated handling of pathogenic viral agents, reinforcing critical safety protocols and gaining firsthand understanding of the biocontainment measures essential in virology research. This practical experience is invaluable for demystifying the often abstract realm of high-containment laboratory work.

Moreover, participants engaged deeply with epidemiological modeling, applying mapping tools and case data to reconstruct outbreak scenarios. This exercise challenged them to interpret complex datasets, identify transmission chains, and propose intervention strategies—all fundamental competencies for public health professionals tackling emergent viral threats. The exercise also highlighted the importance of interdisciplinary collaboration across laboratory science, clinical medicine, and data science in pandemic response.

Addressing the challenge of misinformation, sessions on media literacy equipped students with skills to critically evaluate information streams and recognize the pernicious impact of false narratives on public health. These discussions emphasized how scientific knowledge must be communicated effectively to diverse audiences to safeguard community health and foster trust in health authorities.

The program’s instructors praised the students for their exceptional curiosity, analytical thinking, and collaborative spirit. Catherine White, EdD, a K–12 STEM supervisor with Hillsborough County Public Schools, observed that the program was instrumental in transforming rote scientific facts into engaging narratives that empower students to envision themselves as future innovators and problem-solvers in global health.

The impact of the camp extended beyond mere exposure; several students reported a significant shift in career aspirations, with many expressing newfound motivation to pursue advanced studies in medicine, epidemiology, and virology. The hands-on nature of the program, combined with mentorship from distinguished scientists, created a powerful catalyst for their academic and professional development.

Charles J. Lockwood, MD, MHCM, executive vice president of USF Health and dean of the Morsani College of Medicine, lauded the collaboration as a model for integrating community education with institutional expertise. He projected that Global Guardians could become a key contributor to strengthening the pipeline of qualified scientific leaders poised to address future pandemics, especially as the initiative plans to scale statewide and internationally in the coming years.

The founding premise of the Global Virus Network is the recognition of diminishing numbers of emerging scientists in viral research, a trend that imperils global health security. Dr. Gallo emphasized that programs like Global Guardians play a critical role in reversing this decline by providing early, high-quality educational experiences that underscore the scientific rigor and ethical responsibility necessary in virus research.

Looking ahead, GVN intends to expand the program’s reach and accessibility, incorporating merit-based scholarships to empower diverse students from across Florida and beyond. This inclusivity is crucial to cultivating a workforce reflective of the populations disproportionately affected by viral pandemics, thereby enhancing resilience and equity in public health preparedness.

The inaugural Global Guardians summer camp stands as a testament to the power of targeted education and collaboration between academic institutions, public schools, and global scientific networks. By investing in youth education that combines technical knowledge with leadership development, GVN and its partners are laying the groundwork for sustained innovation and vigilance in combating viral threats worldwide.

The proliferation of ADHD-related TikTok videos demonstrates the platform’s significant influence, particularly among young adults. According to the study, which appeared in the open-access journal PLOS One, fewer than half of the claims made in these viral videos were consistent with guidelines from the Diagnostic and Statistical Manual of Mental Disorders (DSM). This critical gap between TikTok content and clinical understanding raises questions about how these narratives affect public perceptions of ADHD and the experiences of those who live with the disorder.

A notable aspect of the study involved an in-depth examination of 100 of the most popular TikTok videos tagged with #ADHD. Two clinical psychologists meticulously reviewed these videos, analyzing the accuracy of claims regarding ADHD symptoms. Their findings revealed that misinformation is prevalent, where individuals are exposed to narratives that may not only misrepresent ADHD but also contribute to misunderstandings about the disorder itself. This is particularly disconcerting since many young adults turn to social media for reliable information regarding their mental health.

To deepen the analysis, the researchers engaged with a diverse group of 843 undergraduate students, investigating their viewing habits and perceptions of ADHD content on TikTok. The students provided insights into how frequently they consumed ADHD-related videos and how they rated the informational value of content previously assessed by the psychologists. This comparative approach shed light on the stark contrasts between the perspectives of mental health professionals and young adults, revealing complex interactions and the potential for miscommunication in digital spaces.

Students who either self-diagnosed or received formal diagnoses of ADHD reported a higher frequency of engagement with #ADHD TikToks when compared to their peers without the diagnosis. Interestingly, after controlling for various demographic factors and diagnosis status, those who watched these videos more often expressed a proclivity to recommend both the most and least endorsed videos by psychologists. This discrepancy suggests that repetitive exposure to certain narratives may shape their views on ADHD, potentially leading to an overestimation of its prevalence and a distorted understanding of its symptoms.

Furthermore, the researchers observed that individuals who consumed a high quantity of ADHD-related content were inclined to perceive their own symptoms more negatively. Such findings signal a ripple effect wherein the content consumed not only influences participants’ understanding of ADHD but may also complicate their self-assessment and personal experiences. It raises a critical concern regarding the role of social media in shaping the narratives around mental health and disorder, particularly for vulnerable populations.

The study’s authors advocate for further exploration into how ADHD is portrayed across various platforms and the implications of these portrayals for those affected by the disorder. As social media continues to evolve, understanding the discrepancies between professional medical opinions and the perceptions formed by users is crucial. Establishing a dialogue between mental health professionals and social media creators could foster a collaborative effort to promote more accurate information. However, such initiatives would require a robust framework that addresses the rapid rate of information dissemination in the digital age.

As society becomes increasingly reliant on social media for health-related advice, the necessity for research into these digital interactions becomes paramount. This study serves as a foundational step toward a more comprehensive understanding of ADHD narratives on platforms like TikTok. It underscores the responsibility of creators and influencers to be mindful of the content they produce and the potential ramifications it may have on audiences’ understanding of mental health.

Furthermore, researchers emphasize the importance of balancing the benefits of informational content with the potential harm of misinformation. As TikTok and similar platforms facilitate interaction and community building, disseminating accurate and evidence-based content can help cultivate a more informed citizenry. This is particularly essential in ensuring that young adults, who are often in crucial developmental stages, receive the guidance they need to navigate their mental health positively.

The implications of misinformation on platforms like TikTok extend beyond individual perceptions to influence broader societal attitudes toward ADHD. By perpetuating misconceptions, such content can hinder efforts to normalize conversations around mental health. In an era where mental health awareness is gaining momentum, it is imperative to channel that awareness toward reliable, fact-based information that empowers rather than misleads.

In conclusion, although TikTok serves as a dynamic space for sharing knowledge and fostering community support related to ADHD, a cautious approach must be taken. The research by Karasavva and her colleagues opens up vital conversations regarding the accuracy of mental health representations online and the need for a more profound understanding of these digital narratives. As the landscape of social media continues to shift, so too does the responsibility of both creators and consumers to seek truth in the information presented, ultimately striving for a culture of informed discussion around ADHD and mental health.
