For the first time in 20 years, incidence of tuberculosis in the United States increased slightly in 2015, according to investigators from the Centers for Disease Control and Prevention.

In 2015, 9,563 cases of TB were reported in the United States, up 1.7% from the 9,406 cases reported in 2014. Texas saw the largest total increase in TB cases, going from 1,269 cases in 2014 to 1,334 cases in 2015, followed by South Carolina and Michigan, which both had 25 more TB cases in 2015 than in 2014. Vermont saw the largest relative increase, going from two cases in 2014 to seven cases in 2015, an increase of 250%.

Among U.S.-born patients, the largest number of TB cases were reported in black non-Hispanics, although the incidence rate was highest in Native Hawaiian/other Pacific Islanders at 8.4/100,000 people. For foreign-born patients, Mexico was the most common origin country, followed by the Philippines, India, Vietnam, and China. Incidence rate was significantly higher for patients from Asian countries than from any other region.

“Resuming declines in TB incidence will require more comprehensive public health approaches, both globally and domestically. These include increasing case detection and cure rates globally, reducing TB transmission in institutional settings such as health care settings and correctional facilities, and increasing detection and treatment of preexisting latent TB infection among the U.S. populations most affected by TB,” the CDC investigators said.
