Data From: Geographically persistent clusters of La Crosse virus disease in the Appalachian region of the United States from 2003 to 2021

<p>La Crosse virus (LACV) is a mosquito-borne pathogen that causes more pediatric neuroinvasive disease than any other arbovirus in the United States. The geographic focus of reported LACV neuroinvasive disease (LACV-ND) expanded from the Midwest into Appalachia in the 1990s, and most cases have been reported from a few high-risk foci since then. Here, we provide the county-level LACV-ND dataset that we used to investigate changes in the distribution of geographic LACV-ND clusters between 2003 and 2021 and to investigate socioeconomic and demographic predictors of county-level disease risk in states with persistent clusters. We used spatial scan statistics to identify high-risk clusters from 2003–2021 and a generalized linear mixed model to identify socioeconomic and demographic predictors of disease risk.</p>
