Artificial Intelligence as a Threat to Public Health
This page is part of the AI in Public Health Hub.
Artificial intelligence is transforming every sector—including medicine and public health—but with power comes risk. From deepfake health videos to algorithmic bias in diagnostics and predictive analytics, AI introduces new vulnerabilities that threaten evidence, equity, and trust. The same systems designed to accelerate insight can also amplify misinformation, reinforce inequity, and weaken human oversight when it matters most.
This Hub explores how AI technologies, when misused or poorly governed, can harm public health—and what ethical, legal, and structural safeguards are urgently needed to prevent that. The goal is not to reject innovation, but to ensure it serves humanity rather than undermines it.
What You’ll Learn in This Hub
- How generative AI accelerates the spread of false or misleading health information
- Why unregulated algorithms can distort risk assessment, disease surveillance, and healthcare delivery
- What ethical frameworks and data governance principles can help reduce harm
- How to balance innovation with privacy, equity, and accountability
- Why trust, transparency, and human oversight must remain central to public health AI

Why This Hub Matters
AI will shape the next century of public health as much as vaccines shaped the last. But without robust oversight, these same tools could accelerate inequity, misinformation, and harm. This Hub exists to examine that tension honestly. Every article aims to clarify not just what AI can do, but what it should do—and how to build systems resilient enough to use it safely.
Understanding these risks is the first step toward prevention. Ethical guardrails, algorithmic transparency, and public education aren’t optional—they’re essential to ensure AI protects, not endangers, global health.
