While US TB rates reached an all-time low in 2012, with fewer than 10,000 cases reported, approximately one-third of the world’s population is infected with the bacteria that causes TB and close to 4 percent of those newly infected are resistant to multiple drugs from the beginning of treatment. According to the World Health Organization, this signifies that resistant forms of TB are being transmitted directly from person to person. Director of CDC’s Division of TB Elimination Dr. Kenneth Castro emphasized that the global threat of TB underscores the need for continued vigilance in the United States. Most TB cases seen in the United States are occurring among foreign-born individuals, with more than half of the cases coming from just five countries: Mexico, the Philippines, Vietnam, India, and China. In 2011, multidrug-resistant TB, in which the disease is resistant to isoniazid and rifampin, accounted for 1.6 percent of all TB cases where drug susceptibility testing was done.
