MDR TB Cases
United States, 1993 - 1998

Slide 18: Map of MDR TB Cases, 1993-1998.
Slide 18: MDR TB Cases, 1993-1998. During 1993 through 1998, 45 states and the District of Columbia reported at least one multidrug-resistant TB (MDR TB) case (i.e., resistance to at least isoniazid and rifampin, the two most important anti-TB drugs). MDR TB requires the use of second-line anti-TB drugs and a prolonged duration of therapy. Physicians with clinical expertise in the management of MDR TB should always be involved in the care of these patients. Contact investigations around MDR TB cases also require clinical experts to assist in management of infected contacts. All health departments must be prepared to meet the challenge of MDR TB.
