Question 1

What is Disease Weather?

Accepted Answer

Disease Weather is a real-time environmental health intelligence platform built by Orbient LLC. It fuses air quality, pollen, CDC disease activity, NWS disaster alerts, and weather into a single Environmental Health Index (EHI) score for any US location. It is designed for people living with respiratory conditions, immunocompromise, and chronic disease.

Question 2

What is the Environmental Health Index (EHI)?

Accepted Answer

The Environmental Health Index (EHI) is a 0-100 composite score that fuses air quality, disease activity, and environmental conditions into a single number. Lower is healthier. It is computed using the EDAL (Environmental Disease Activity Layer) — a patent-pending AI fusion engine developed by Orbient LLC. Domain weights shift seasonally: air quality and environment carry more weight May-August when ozone and pollen dominate; disease activity carries more weight December-February during peak respiratory season. A compound condition multiplier activates when PM2.5 and pollen are simultaneously elevated, reflecting the additional respiratory burden of co-exposure.

Question 3

What data does Disease Weather use?

Accepted Answer

Disease Weather uses NASA TEMPO satellite (NO2, ozone, HCHO at neighborhood resolution), OpenAQ and Open-Meteo CAMS for air quality and PM2.5, ECMWF IFS as a secondary weather model for corroboration, Google Pollen API for pollen, CDC ILINet via Delphi Epidata for respiratory disease activity, NWSS for wastewater surveillance, a seasonal vector-borne disease risk proxy based on CDC ArboNET historical patterns (Lyme disease May-Oct, West Nile Jul-Sep, EEE Aug-Oct for Northeast), Open-Meteo for weather, NOAA CPC for ENSO state, NWS CAP API for disaster alerts updated every 60 seconds, RainViewer for animated precipitation radar, and WHO Disease Outbreak News for active international outbreak advisories.

Question 4

Is Disease Weather free?

Accepted Answer

Yes. Disease Weather is free for all US locations. Disease Weather+ ($4.99/month or $39/year) adds personalized EHI calibrated to your health profile, wearable biometric integration, push notifications, and a 24-48 hour forecast. Disease Weather Global ($2.99/month) adds international coverage.

Question 5

Who builds Disease Weather?

Accepted Answer

Disease Weather is built by Orbient LLC, a health technology company founded by Mark Hardy and headquartered in Cranston, Rhode Island. Orbient also builds Sphere Aware, a clinical SaMD for respiratory and immunocompromised patients pursuing FDA clearance.
