Generative AI and health misinformation: production, propagation, and mitigation—a systematic review

Generative AI transforms the health misinformation landscape by lowering barriers to creation and exploiting platform and behavioral dynamics.

Future work must prioritize multimodal, multilingual, and health‑specific verification, as well as real‑world testing of interventions, to build equitable and resilient health information ecosystems.
