Simple Estimates for Local Prevalence of Latent Tuberculosis Infection, United States, 2011–2015

This is the authors' abstract. We don't add key points for this paper.

We used tuberculosis genotyping results to derive estimates of prevalence of latent tuberculosis infection in the United States. We estimated <1% prevalence in 1,981 US counties, 1%-<3% in 785 counties, and >3% in 377 counties. This method for estimating prevalence could be applied in any jurisdiction with an established tuberculosis surveillance system.
