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 2011, approximately 62% of TB cases in the United States occurred in foreign-born individuals.
• The majority of U.S. cases among foreign-born individuals are in people from 7 countries (Mexico, Philippines, Vietnam, India, China, Haiti, and Guatemala).

• For a list of high burden countries and profiles of these countries, see the Stop TB Partnership website.
