Description:BACKGROUND:
After a steady decline for 20 years, the pace of decline of TB incidence in the United States has slowed.
METHODS:
Trends in TB incidence rates and case counts since 1993 were analyzed using national US surveillance data. Patient characteristics reported during 2014–2017 were compared with those for 2010–2013.
RESULTS:
TB rates and case counts have slowed to an annual decline 2.2% (95% confidence interval (CI): –3.4– –1.0) and 1.5% (95% CI: –2.7– –0.3) respectively, since 2012, with declines among US-born persons and no change among non-US–born persons. Overall, persons with TB diagnosed during 2014–2017 were older, more likely to have combined pulmonary and extrapulmonary disease compared with exclusively extrapulmonary disease, more likely to be of nonwhite race, and less likely to be human immunodeficiency virus-positive, or have cavitary pulmonary disease. During 2014–2017, non-US–born persons with TB were more likely to have diabetes while the US-born were more likely to have smear positive TB and use noninjecting drugs.
CONCLUSION:
Changes in epidemiologic trends are likely to affect TB incidence for coming decades. CDC has called for increased attention toward preventing TB through detection and treatment of latent TB infection.
