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

Maryam B Haddad et al. Emerg Infect Dis. 2018 Oct.

Abstract

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.

Keywords: Mycobacterium tuberculosis; United States; bacteria; estimates; infection; latent tuberculosis; molecular epidemiology; prevalence; public health surveillance; respiratory infections; tuberculosis; tuberculosis and other mycobacteria.

Estimated prevalence of latent tuberculosis infection, by county, United States, as derived from genotyped cases of tuberculosis reported to the US National Tuberculosis Surveillance System, 2011–2015. County equivalents (i.e., Alaska boroughs, District of Columbia, Louisiana parishes, and Virginia independent cities) are also shown. A modified method for analyzing data for Oklahoma is found in the text. Prevalence estimates for Alaska are aggregated by region.
