US tuberculosis cases drop almost 20 percent among foreign-born entrants from 2007-2011

The reasons behind a 19% drop in US tuberculosis (TB) cases among foreign-born people between 2007-2011 vary depending on the person's country of origin and when they entered the U.S., according to a study published in the open-access journal PLOS ONE.While the overall number of TB cases in the U.S. has declined over the past two decades, TB morbidity among foreign-born people remains persistently elevated. Beginning in 2007, scientists observed a sharp decline in TB cases among recent U.S. entrants. The authors assessed whether this decrease was because of changes in population size or through decreased incidence of TB. Specifically, they looked at TB case counts, TB case rates, and population estimates by time since U.S. entry, using the U.S. National Tuberculosis Surveillance System and the American Community Survey.
