Tuberculosis control in the 21st century.

In response to tuberculosis (TB) outbreaks in the United States in the late 1980s and early 1990s, U.S. hospitals spent tremendous resources to ensure a safer workplace. A remarkable decrease in nosocomial transmission resulted, along with a decrease in TB cases nationally. Federal standards have been promulgated to ensure a safer work environment for all U.S. workers potentially exposed to TB. However, these measures may prove costly and burdensome and thus may compromise the ability to deliver care.
