The case data in this report are compiled from those reports submitted through the local health departments. The cases are verified and categorized into three general categories. This category includes those cases where the physician has determined the individual has TB, is treating with an appropriate regimen, and the patient is improving clinically. Many in this category include extrapulmonary TB and children where laboratory confirmation may be lacking due to the disease site. The following table summarizes the reported TB cases by verification criteria.
Pulmonary cases are of particular concern since disease transmission can occur.
In order to interrupt this cycle of transmission, appropriate therapy must be initiated and continued for the duration of the therapy period. Since 1993, an initial drug regimen consisting of three or four drugs has been promoted. Preventing the emergence of drug resistance is a major public health challenge. DOT is now a standard of care in Indiana. Drug resistance was documented in Lake, LaPorte, Delaware, Marion, Vigo, Scott, and Posey counties.
