1997 Surveillance Slides

Change in TB Cases by Country of Origin
United States, 1986, 1992 and 1997

Slide 17: Change in TB Cases by Country of Origin United States, 1986, 1992 and 1997.
Slide 17. During 1986 through 1992, the number of TB cases among foreign-born persons increased by 47.6%, whereas the number in U.S.-born persons increased by 8.5%. During 1992 through 1997, the number of TB cases in foreign-born persons increased by 5.9%, whereas the number decreased by 38.1% in U.S.-born persons. Most TB cases among foreign-born persons are likely the result of reactivation of remotely acquired infection, although some transmission is probably occurring in the United States. To reduce active TB disease among foreign-born persons, CDC, in collaboration with state and local health departments, has developed a comprehensive plan that includes strategies to (1) improve case finding and completion of therapy in persons with TB disease, (2) conduct contact investigations, and (3) screen those at high risk for infection, and ensure completion of preventive therapy in eligible candidates (MMWR 1998;47 [No. RR-16]).
