In an age of unprecedented information access, researchers are sounding the alarm about a growing challenge in public health communication: the “infodemic.” This term, recognized by the World Health Organization, describes the overwhelming volume of information—both accurate and misleading—that can undermine effective health decision-making during disease outbreaks and other public health crises.
Recent studies have highlighted how misinformation spreads and influences different demographics. A groundbreaking 2019 study published in Science Advances by Guess, Nagler, and Tucker found patterns in how false information disseminates through social networks, with important implications for public health messaging strategies.
Building on this research, Allen and colleagues demonstrated in 2020 that exposure to misinformation can significantly alter health behaviors, creating challenges for public health officials trying to promote evidence-based practices. Their work, also published in Science Advances, pointed to concerning trends in how misinformation can override factual public health guidance.
A particularly vulnerable demographic has emerged in this landscape. New research by Lyons, King, Barter, and Kaphingst published in Nature Aging reveals that older adults may be disproportionately susceptible to health misinformation. This finding raises concerns as this population often faces higher health risks and requires accurate information to manage chronic conditions.
The Centers for Disease Control and Prevention has responded by launching targeted campaigns addressing this issue. In a 2025 report from their Preventing Chronic Disease publication, the CDC outlined strategies specifically designed to combat health misinformation among high-risk populations.
Health communication experts Nan, Wang, and Thier have become leading voices in this field. Their chapter in The Routledge Handbook of Health Communication (2021) established a framework for understanding how misinformation undermines public health initiatives. The team further expanded on these concepts in a 2022 Social Science & Medicine paper, where they documented how misleading health claims can impact vaccination rates and preventative care behaviors.
Trust plays a crucial role in determining which information sources people rely upon. The 2024 Edelman Trust Barometer report for Singapore revealed a concerning trend: public trust in traditional health information sources has declined while reliance on unverified social media sources has increased. This shift creates fertile ground for misinformation to flourish.
In unpublished work currently available as a preprint, Wang, Thier, and Nan have developed potential intervention strategies to combat health misinformation. Their approach focuses on building critical evaluation skills among consumers of health information rather than simply correcting false claims after they’ve spread.
Additional research from Harvard’s Kennedy School of Government has identified demographic patterns in susceptibility to health misinformation. A 2020 study led by Guess found that digital literacy, not just age, plays a significant role in determining who falls prey to misleading health claims.
Public health officials are now incorporating these findings into comprehensive communication strategies. Nan, Thier, and Wang’s 2023 article in the Annals of the International Communication Association outlined a roadmap for health organizations to effectively combat misinformation while maintaining public trust.
As information ecosystems continue to evolve, the challenge of ensuring accurate health information reaches the public remains significant. Experts suggest that solutions will require collaboration between health organizations, technology platforms, media outlets, and the public to create information environments that prioritize accuracy and accessibility in health communications.
