About PublicHealthAlert
What this is
PublicHealthAlert is a public information dashboard that aggregates outbreak signals, travel advisories, imported cases, and lineage updates from public health publishers and presents them as a single reverse-chronological feed organized around the question that matters most for U.S. residents: what started abroad and now has a U.S. link?
What this is not
- It is not a medical advice service. Always consult your physician or local public-health authority for clinical decisions.
- It is not a real-time emergency alerting system. Updates are nightly. For emergencies, follow CDC and WHO directly.
- It does not include any fabricated, simulated, or seeded events. Every row on this dashboard came from a public publisher you can click through to.
How it works
Each night at 01:00 ET a Node.js scraper running on the operator PC pulls the latest content from CDC, WHO Disease Outbreak News, ECDC, PAHO, and Africa CDC. Rows are normalized into a common schema, deduplicated, and archived locally. At 02:00 ET a verifier validates freshness and source health, then pushes the result to GitHub and deploys to Netlify. If verification fails, the previous good day is republished with a status: stale flag instead of going empty.
Priority pathogens
The tracker watches every virus its keyword classifier can identify, but six are pinned as priority because of active 2026 cross-border movement and U.S. relevance:
- Measles — currently the most directly relevant to U.S. importation risk. Travelers and under-vaccinated communities drive amplification.
- Chikungunya — large 2026 case totals in South America, especially Brazil and Suriname; risk is travel-imported plus local vector competence.
- Poliovirus — Level 2 advisory issued in March 2026 covering 30+ countries with active circulation.
- Oropouche — expansion from the 2024 Americas outbreak footprint with documented U.S. and Canada imported cases.
- Avian influenza — H5N1 / H9N2 / H7N9 zoonotic signals with cross-border traveler events.
- Yellow fever — Venezuela travel notice issued March 2026; U.S. risk is unvaccinated travelers returning from outbreak areas.
Data integrity
The full source code is open at github.com/garyamick0614-creator/PublicHealthAlert. Every nightly publish becomes a git commit on main, so the publish history is fully reproducible — you can see exactly which event entered the feed when, and which version of the scraper produced it.
null field over a guess. If you spot something wrong, file an issue — the classifier patterns are transparent and easy to amend.
