Despite the existence of curative therapy for disease, effective treatment for infection, and the fact that the bacillus Calmette-Guerin (BCG) vaccination has been given to approximately 4 billion people, Mycobacterium tuberculosis remains the single pathogen causing the most disease and death in the world today. The World Health Organization (WHO) has estimated that during the 1990s, there will be 90 million cases of tuberculosis and 30 million deaths caused by tuberculosis throughout the world.<sup>44 Raviglione M.C., Snider D.E., Kochi A.

Many industrialized countries, including the United States, have experienced a resurgence of tuberculosis during the past 10 years. Although the burden of infection and disease has been far less in these countries than in the developing world, this resurgence has received attention because it reflects a weakening of the public health system in these countries. The pool of persons infected with M. tuberculosis in the United States has increased dramatically during the past decade. Many primary care practitioners who previously had little experience with tuberculosis-related issues now find themselves facing these problems fairly regularly.

The purpose of this article is to address tuberculosis from the point of view of the busy primary care practitioner who cares for children in the United States. During the past few years, the Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP)<sup>2 American Academy of Pediatrics Report of the Committee on Infectious Diseases Elk Grove, Illinois: American Academy of Pediatrics (1994).  480500

Although these recommendations are based on good science and public health principles, they are sometimes difficult to apply in an office practice. With some fairly simple changes in approach,

however, the primary care practitioner can address tuberculosis-related issues in a fairly simple and straightforward manner.
