Real-time environmental health intelligence for any US location. Air quality, pollen, community disease activity, and environmental conditions — fused into a single plain-English score so you can make smarter decisions about your day, your family, and your health.
Weather apps tell you what to wear. Disease Weather tells you what your environment means for your health — right now, for your location, in plain English. No medical background required. No subscription. No paywall.
We believe the kind of environmental health intelligence that today only exists inside research institutions and public health agencies should be available to everyone. That's why we built Disease Weather — and why we made it free.
The EHI fuses signals across three environmental health domains into a single 0–100 score. Lower is healthier. Each domain updates continuously from authoritative public data sources.
Climate change is reshaping environmental health risk in real time. These new capabilities help you understand what that means for you today.
Every signal in Disease Weather comes from a named, authoritative source. No black boxes. No proprietary indexes you can't verify.
Disease Weather is the consumer layer of a larger One Health intelligence platform — Tropos OPI — that spans clinical AI, facility biosurveillance, pharmaceutical environmental monitoring, and beyond. We built Disease Weather because we believe this intelligence should be available to everyone, not just institutions. Nearly 1,000 monthly visitors from 49 countries have found it organically. The need isn't American. It's human.
