The resurgent tuberculosis epidemic represents--especially in New York City--a failure to maintain a public health infrastructure that was focused on preventing active disease in high-risk populations (i.e., individuals with the human immunodeficiency virus [HIV]) and on treating active tuberculosis patients until cured. Although the tuberculosis problem in New York City and other localities is worsened by homelessness, poverty, and substance abuse, it is possible to bring tuberculosis under control by directing public health resources into targeted programs that enhance compliance with tuberculosis treatment regimen and expand chemoprophylaxis efforts among HIV-infected individuals. These two avenues will decrease, respectively, the number of cases of multidrug-resistant tuberculosis and the total number of new cases.
