Preventing Hepatitis B Transmission from Husband to Wife

Hepatitis B virus (HBV) transmits efficiently through sexual contact and shared blood exposure. For a serodiscordant couple (husband HBV+, wife susceptible), these measures dramatically reduce transmission risk:

1. Vaccination (Most Effective)

Wife completes 3-dose series (0, 1, 6 months). Check anti-HBs titer 1–2 months post-series; ≥10 mIU/mL = immune. Booster if non-responder.

2. Barrier Protection

Condoms for all penetrative sex until wife is confirmed immune. Reduces exposure to HBV in semen/vaginal fluids.

3. No Sharing of Blood-Contaminated Items

• Toothbrushes (gingival bleeding)
• Razors, nail clippers
• Glucose monitors, injection equipment

4. Wound Care

Cover cuts/abrasions immediately. Clean blood spills with 1:10 bleach solution.

5. Husband's Viral Suppression

If husband has chronic HBV, nucleos(t)ide analog therapy (entecavir/tenofovir) reduces HBV DNA to undetectable, lowering transmission risk further.

6. Regular Monitoring

Both partners: LFTs, HBV serology/PCR per hepatologist schedule.

With vaccination + condoms + no sharing, transmission risk approaches zero. Consult a hepatologist for personalized guidance.
