All of the following are true regarding HIV transmission and risk factors in India EXCEPT:

Question

Accepted Answer

C. Needle and syringe sharing among people who inject drugs accounts for less than 5% of total HIV infections in India and is therefore not a priority for intervention. ## HIV Transmission Routes and Risk Factors in India

### Correct Statements

**High-Yield:** Transmission probability per act varies significantly:
- **Receptive anal intercourse:** ~1.38% (highest risk)
- **Receptive vaginal intercourse:** ~0.08%
- **Insertive anal intercourse:** ~0.62%
- **Insertive vaginal intercourse:** ~0.04%

**Key Point:** Blood transfusion-related HIV transmission in India has been **effectively controlled** through:
- Mandatory screening of all blood units since 1998
- Residual risk now **<1 in 10 million** transfusions
- Implementation of WHO guidelines for blood safety

**Clinical Pearl:** Occupational exposure through needlestick injury carries **~0.3% per-incident risk**, justifying immediate post-exposure prophylaxis (PEP) within 72 hours for healthcare workers.

### The Incorrect Statement (Correct Answer)

**Warning:** Needle and syringe sharing among PWID is **NOT a minor transmission route** in India. This statement is false because:
- PWID account for **5–10%** of total HIV infections nationally
- In certain states (Manipur, Nagaland, Mizoram), PWID represent **30–50%** of HIV cases
- This is a **key population** requiring targeted intervention
- Harm reduction programs (NSP, OST) are priority interventions

### HIV Transmission Risk Stratification

| Route | Per-Act Risk | Status in India |
| --- | --- | --- |
| Receptive anal intercourse | 1.38% | High-risk key population |
| Receptive vaginal intercourse | 0.08% | Heterosexual transmission |
| Insertive anal intercourse | 0.62% | MSM population |
| Needlestick injury (occupational) | 0.3% | Healthcare worker risk |
| Blood transfusion | <1 in 10 million | Effectively controlled |
| Needle/syringe sharing (PWID) | Variable, high cumulative | **KEY POPULATION** |

### PWID as a Key Population in India

**Mnemonic: PWID Priority — NE States High** (Northeast states have highest PWID-related HIV burden)
- Manipur: ~30–50% of HIV cases in PWID
- Nagaland: ~40–60% of HIV cases in PWID
- Mizoram: ~25–35% of HIV cases in PWID
- National average: ~5–10% of total HIV infections

[cite:Park 26e Ch 7; NACO Guidelines 2023]

Answer

A. Occupational exposure to HIV through needlestick injury carries an average per-incident transmission risk of approximately 0.3%, making post-exposure prophylaxis (PEP) critical for healthcare workers

Answer

B. Blood transfusion-related HIV transmission has been effectively controlled in India through mandatory screening of all blood units since 1998, resulting in residual risk of less than 1 in 10 million

Answer

D. Unprotected receptive anal intercourse carries a per-act transmission probability of approximately 1.38%, which is higher than receptive vaginal intercourse at 0.08%
