Global and regional burden of measles and vaccine coverage among children under 5 years, 1990−2023: a Global Burden of Disease Study

Global Burden of Disease Study's latest release — showing that measles incidence and mortality, after decades of decline, have rebounded since 2020 due to stalled vaccination coverage — highlights a sudden surge in public interest and misinformation searches around childhood immunisation. For website owners, this resurgence translates into a measurable spike in AI‑generated traffic seeking quick answers on measles symptoms, vaccine safety, and outbreak maps. Bots powered by large language models are being deployed by health‑tech startups, news aggregators, and even malicious actors to harvest queries and serve targeted content. The spike can inflate analytics, skew SEO metrics, and expose sites to reputational risk if AI‑generated answers are inaccurate or unverified. **Actionable tips:** 1. **Update your llms.txt** to explicitly disallow generic health‑information crawlers (e.g., “User‑Agent: *HealthBot* Disallow: /”) while permitting trusted medical APIs. 2. **Implement bot‑traffic segmentation** in your analytics platform, flagging spikes in “/measles‑*” or “/vaccination‑info” endpoints and cross‑referencing them with known LLM user‑agents. 3. **Deploy a verification layer** that checks incoming AI‑generated queries against WHO vaccination data before serving auto‑generated content, reducing the chance of spreading outdated or harmful information.
