2. Why TB-HIV co-infection is important ? TB is the most common opportunistic infection affecting HIV-seropositive individuals, and it remains the most common cause of death in patients with AIDS. Worldwide, 14.8% of TB patients have HIV co- infection. TB is the most common cause of death among patients with AIDS, killing 1 of 3 patients.

3. Why TB HIV co-infection is special ? HIV alters the pathogenesis of TB, greatly increasing the risk of disease from TB in HIV co infected individuals and leading to more frequent extra pulmonary involvement. Atypical radiographic manifestations, and paucibacillary disease, which can delay timely diagnosis.

7. Steps for HIV Counseling & Testing

8. Patient selection for HIV screening : It is ideal to sent all the patients of tuberculosis to HCT center, but due to low prevalence of HIV infection we choose the patients with high risks. The prevalence of HIV remains very low (<0.1%) in the general population and low (<1%) in most at-risk populations (MARPs).

The prevalence of HIV remains very low (<0.1%) in the general population and low (<1%) in most at-risk populations (MARPs).

9. Links between HIV & TB o Generally the lifetime risk of developing active TB is around 10% o While for TB/HIV co-infection the risk may be upto 60%

10. Which patients of tuberculosis are in possible risk of HIV infection ? o 1 ) TB or TB suspects with history of high risk behavior (IDU, unsafe blood transfusion, SW, migrant workers, H/O STI, MSM, transgender/hijra). o 2) MDR-TB o 3) Relapse and treatment failure TB cases o 4) Complicated extra-pulmonary TB o 5) Clinical suspects of HIV infection o 6) Children of mother known to be HIV-positive o 1 ) TB or TB suspects with history of high risk behavior (IDU, unsafe blood transfusion, SW, migrant workers, H/O STI, MSM, transgender/hijra). o 2) MDR-TB o 3) Relapse and treatment failure TB cases o 4) Complicated extra-pulmonary TB o 5) Clinical suspects of HIV infection o 6) Children of mother known to be HIV-positive
