“Targeted screening is recommended only for individuals and groups at increased risk of TB infection.5 Routine testing outside of high-risk groups leads to more false-positive results, creates needless anxiety, and wastes resources.5 High-risk groups include recent immigrants (within the past five years) from high-incidence countries, health care professionals, persons living or working in institutional settings, and homeless persons.4 High-incidence areas include most of the countries in Africa, Asia, eastern Europe, Central America, and South America. Asian immigrants in the United States are at significant risk, with 25 times the rate of active TB compared with non-Hispanic whites.9 The only low-risk persons who should be screened are those who will be entering a high-risk group in the future, such as for work or travel.” AAFP
