Cost-effective implementation of tick- and host-targeted control methods requires an understanding of the relationship between pathogen prevalence in nymphs, nymph abundance, and incidence of human cases of Lyme disease. We quantified the relationship between estimated acarological risk and human incidence using county-level human case data and nymphal prevalence data from field-derived estimates in 36 eastern states. The estimated density of infected nymphs (mDIN) was significantly correlated with human incidence (\n                    <jats:italic>r<\/jats:italic>\n                    = 0.69). The relationship was strongest in high-prevalence areas, but it varied by region and state, partly because of the distribution of\n                    <jats:italic>B. burgdorferi<\/jats:italic>\n                    genotypes.
