TB Testing and Treatment
Three basic strategies are critical to the prevention and control of TB:
- Identifying and completely treating all persons who have active TB.
- Finding and evaluating persons who have had contact with TB patients, determining if they have TB infection or disease, and treating them appropriately (contact investigations). Contact investigations are important for identifying persons who have active TB and infected persons at high risk for developing TB.
- Screening populations at high risk for TB to locate persons infected with TB and giving complete therapy to prevent the infection from progressing to active, contagious disease. This screening also may identify cases of active disease.
