Approaches for TPT implementation
Learning Objectives2 Approaches - Test and Treat, Treat Only
There are two programmatic approaches for Tuberculosis Preventive Therapy (TPT) implementation:
1. Test-and-treat approach – This approach aims to detect TB infection among key groups for implementing TPT.
- After ruling out active TB, the beneficiary is tested for TB infection.
- TPT is offered only to those with a positive test (Interferon Gamma Release Assay (IGRA)/ Tuberculin Skin Test (TST)/ Cutaneous TB (C-TB))
2. Treat-only approach – For certain groups, like People Living with HIV (PLHIV) and House Hold Contact persons (HHC) < 5 years old, detecting TB infection is not required. Hence, this approach is given.
- After ruling out active TB, TPT is offered without testing for TB infection.

#PLHIV < 1 year old are offered TPT only if they are a household contact persons of an active TB case.
