The Wall Street Journal profiles the case of a man infected with extensively drug-resistant tuberculosis (XDR-TB) who is being detained in South Texas after a "three-month odyssey through 13 countries -- from his homeland of Nepal through South Asia, Brazil, Mexico, and finally into Texas -- show[ing] the way in which dangerous new strains of the disease can migrate across the world unchecked." The newspaper notes, "In recent months the Wall Street Journal has exposed widening TB drug resistance in hot spots like India, and shown that the U.S. is surprisingly unprepared for the growing global problem," adding, "Most U.S. cases of drug-resistant TB occur in people who were born abroad, according to the [CDC]."
