Toward a generation free of tuberculosis: TB disease and infection in individuals of college age in the United States.

OBJECTIVES

To assess the magnitude of active TB disease and latent TB infection (LTBI) in young adults of college age.

PARTICIPANTS

Individuals who were aged 18-24 years in 2011 were used as a proxy for college students.

METHODS

Active TB cases reported to the 2011 US National TB Surveillance System (NTSS) were included. LTBI prevalence was calculated from the 2011-2012 National Health and Nutrition Examination Survey. The 2011 American Community Survey was used to calculate population denominators. Analyses were stratified by nativity.

RESULTS

Active TB disease incidence among persons aged 18-24 years was 2.82/100,000, 18.8/100,000 among foreign-born individuals and 0.9/100,000 among US-born individuals. In 2011, 878 TB cases were reported; 629 (71.6%) were foreign-born. LTBI prevalence among persons of 18-24 years was 2.5%: 8.7% and 1.3% among foreign-born and US-born, respectively.

CONCLUSION

Active screening and treatment programs for foreign-born young adults could identify TB cases earlier and provide an opportunity for prevention efforts.
