PopHIVE provides harmonized US public health surveillance data from the Yale School of Public Health. Ask about respiratory disease activity (RSV, flu, COVID, measles), chronic disease prevalence (diabetes, obesity), injury trends (overdose, firearm, heat illness), and childhood vaccination coverage across US states and counties. Signals are synthesized from CDC systems, Epic Cosmos, wastewater monitoring, Google Health Trends, and more. Every level, trend, rank, and correlation is computed server-side with full provenance, caveats, and a deep link to the matching pophive.org chart. All data is public, aggregate, and de-identified.
You can use PopHIVE to:
Track respiratory disease activity:
"How is flu trending in the US right now?"
Compare chronic disease prevalence by geography:
"Which US states have the highest diabetes prevalence?"
Monitor injury trends:
"Show overdose trends in Ohio counties over the last year."
Check childhood vaccination coverage:
"What's MMR vaccination coverage by state?"
