Town-level environmental data for 29,329 towns across 38 US states, plus state-level arbovirus surveillance (West Nile and Eastern Equine Encephalitis), the open data behind a daily mosquito-risk forecast.
Maintained by MosquitoZone, a free daily mosquito-risk forecast for every town it covers. See the methodology for how risk is scored.
One row per town, with place identifiers, geography, and the environmental covariates that drive local mosquito habitat.
