Guide for Primary Health Care Providers: Targeted Tuberculin Testing and Treatment of Latent Tuberculosis Infection

Appendix B

Identifying Persons from High-Risk Countries

  • Local epidemiologic profiles are the most useful resource to identify countries of highest risk. Health care providers should base testing and treatment decisions on local immigration patterns and epidemiology.
  • In 2003, 53% of TB cases in the U.S. occurred in foreign-born individuals.
  • More than 60% of U.S. cases among foreign-born individuals reported in 2003 were in people from seven countries (Mexico, Philippines, Vietnam, India, China, Haiti, and South Korea).
