An infodemic refers to an overabundance of information, both accurate and false, that spreads rapidly during an epidemic or crisis, making it difficult for people to find trustworthy sources and reliable guidance. The term is a blend of "information" and "epidemic". It highlights how the proliferation of information can parallel the spread of disease, creating additional challenges in managing the primary crisis. The term rose to prominence in 2020 during the COVID-19 pandemic. During epidemics, accurate information is even more critical than in normal times because people need it to adjust their behavior to protect themselves, their families, and their communities from infection (World Health Organization, 2020).
Contradictory messages and conflicting advice can create confusion and mistrust among the public (Borges et al., 2022). An infodemic can intensify or lengthen outbreaks when people are unsure about what they need to do to protect their health and the health of people around them. The situation is so dire that the World Health Organization (2020) published guidance to help individuals, community leaders, governments, and the private sector understand some key actions they can take to manage the COVID-19 infodemic.
Characteristics of Infodemics
Infodemics result in more information than most people can process effectively, especially those with low health literacy. With growing digitization, information spreads more rapidly. Alongside accurate information, a significant amount of misinformation (false or misleading information shared without harmful intent) and disinformation (false information deliberately spread to deceive) is disseminated. Information spreads quickly, particularly through interconnected social media and digital platforms, reaching global audiences instantaneously. Infodemics often feature highly emotional, sensational, or alarming content that captures attention but may not be accurate or helpful.
Examples of Infodemics
Three global epidemics have occurred in recent memory, each accompanied by infodemics:
- COVID-19 Pandemic: During the COVID-19 pandemic, an infodemic emerged with vast amounts of information about the virus, treatments, vaccines, and public health measures. This included a significant spread of misinformation and conspiracy theories.
- Ebola Outbreaks: Past Ebola outbreaks have seen infodemics where misinformation about the disease’s transmission and treatments spread rapidly, complicating response efforts.
- Zika Virus: The Zika virus outbreak was accompanied by an infodemic, with rumors and false information about the virus’s effects and prevention measures.
Understanding and addressing infodemics is crucial for effective crisis management and public health response, ensuring that accurate information prevails and supports informed decision-making by individuals and communities. With human encroachment on natural areas, the likelihood of future epidemics is high (Shafaati et al., 2023).
Consequences of Infodemics
The flood of conflicting information can cause confusion, anxiety, and stress, making it hard for individuals to know how to respond appropriately to the crisis. Trust in authorities, experts, and media can be eroded when people encounter inconsistent messages or feel they are being misled. Misinformation can lead to harmful behaviors, such as using unproven treatments, ignoring public health advice, or spreading conspiracy theories. The spread of false information can hamper public health responses and crisis management efforts, as resources may be diverted to combat misinformation instead of focusing solely on the crisis. The plethora of unreliable health information delays care provision and increases the occurrence of hateful and divisive rhetoric (Borges et al., 2022). Infodemics can exacerbate social divisions, as different groups may cling to varying sets of information and beliefs, leading to polarized views and conflicts.
Managing Infodemics
Another new term is “infodemiology,” a combination of information and epidemiology. Epidemiology, the study of the distribution of health and disease patterns within populations to use this information to address health issues, is a fundamental aspect of public health. It aims to minimize the risk of adverse health outcomes through community education, research, and health policy development (World Health Organization 2024). Infodemiology is the study of the flood of information and how to manage it for public health. Infodemic management involves systematically applying risk- and evidence-based analyses and strategies to control the spread of misinformation and mitigate its effects on health behaviors during health crises.
For example, in their systematic review of publications about health infodemics and misinformation, Borges et al. (2022) commented that “social media has been increasingly propagating poor-quality, health-related information during pandemics, humanitarian crises and health emergencies. Such spreading of unreliable evidence on health topics amplifies vaccine hesitancy and promotes unproven treatments” (p. 556). However, they noted that social media has also been successfully employed for crisis communication and management during emerging infectious disease pandemics and significantly improved knowledge awareness and compliance with health recommendations. For governments, health authorities, researchers, and clinicians, promoting and disseminating reliable health information is essential to counteract false or misleading health information spread on social media.

Strategies for Combating Infodemics
For government officials, public health professionals, and educators, preparation is essential to prevent the next pandemic disaster (Shafaati et al., 2023). Strengthening public health services and investing in research and development for new medications and vaccines are crucial steps. Expanding access to education and resources in vulnerable communities is also necessary to enhance understanding and encourage preventive actions. Additionally, investing in international cooperation is vital to support countries at risk of outbreaks and provide economic assistance to those affected by pandemics.
- Promoting Accurate Information: Authorities and experts must provide clear, accurate, and timely information. This includes regular updates from trusted sources like public health organizations.
- Media Literacy: Enhancing public media literacy can help individuals critically evaluate the information they encounter, recognize reliable sources, and avoid sharing unverified claims.
- Fact-Checking and Verification: Fact-checking organizations and platforms are crucial in verifying information and debunking false claims. Prominent placement of fact-checked information can help correct misconceptions.
- Algorithmic Adjustments: Social media platforms and search engines can adjust their algorithms to prioritize credible sources and reduce the visibility of misleading content.
- Collaboration and Coordination: Effective communication and coordination among governments, health organizations, media, and tech companies are essential to manage the flow of information and combat misinformation.
- Public Engagement: Engaging with communities and addressing their concerns directly can build trust and ensure accurate information reaches diverse audiences. This may include town hall meetings, Q&A sessions, and community-specific communications.
