Why is tuberculosis out of control? What prompted a change in U.S. health policy? In the revised edition of the 1994 book, the editor has updated his bestseller to address the new challenge tuberculosis is presenting to both the medical community and the general public. The emphasis in the United States has changed to directly observe treatment, concentrating on foreign-born individuals. Not only do the authors address transmission and control issues, but they offer the latest information concerning the treatment of drug-resistant strains of the disease, HIV-infected patients, and the alarming TB rates in developing countries.
