Summary: During Hurricane Helene, misinformation spread rapidly across media platforms, complicating public understanding and response efforts. As the storm neared, false information fueled confusion and anxiety, particularly among vulnerable populations, undermining the effectiveness of official, fact-based communication. Much of this misinformation originated on social media, where users shared unverified and often sensationalized updates about the hurricane’s impact. This phenomenon highlighted the dangers of “weaponized health communication.” Traditional and non-traditional media played significant roles in spreading misinformation. In the rush to deliver updates, news outlets reported on speculative scenarios, sometimes based on unnamed sources, which blurred the lines between fact and fiction. This resulted in conflicting messages, leaving the public uncertain about which actions to take and which guidance to trust. A public health, disaster management, and medicine literature review examined how misinformation (MDM) spreads during crises. Case studies from domestic and international contexts revealed key themes about state-sponsored information operations, the role of social media, and the challenges posed by public distrust. These insights informed potential countermeasures to mitigate MDM in future crises. Various organizations, including governments, militaries, and non-governmental institutions, have developed strategies to counter MDM in public health and disaster contexts. However, widespread distrust in government and the effectiveness of MDM campaigns on social media complicate these efforts. Countermeasures like Inoculation Theory, which has been used to combat climate science denial and anti-vaccine misinformation, show promise in mitigating malicious MDM. By using targeted messaging to “inoculate” the public against false narratives, these methods could help protect vulnerable populations during critical events.
