Task force recommends TB screening for at-risk populations

The U.S. Preventive Services Task Force now recommends people at increased risk for tuberculosis infection — such as people who were born in or have lived in countries with high TB prevalence or who lived in areas where TB exposure is more likely, like a homeless shelter or jail — be screened for latent TB infection.

The recommendation was published in Tuesday’s issue of JAMA.

“The USPSTF found adequate evidence that accurate screening tests for [latent TB infection] are available, treatment of LTBI provides a moderate health benefit in preventing progression to active disease, and the harms of screening and treatment are small,” according to the recommendation.

Latent TB infections are asymptomatic and not infectious, but can progress to an active TB infection if not treated. LTBI prevalence is estimated to be around 5 percent of the U.S. population.
