# Pregnancy & Delivery with Asymptomatic Genital HSV-1

**The reassuring reality:** Asymptomatic HSV-1 genital infection carries *significantly lower* transmission risk to a newborn compared to symptomatic infection or HSV-2. Most pregnancies with asymptomatic HSV-1 proceed without complication.

**During pregnancy:**
Your immune system produces antibodies that provide substantial protection to your baby. Prenatal transmission (across the placenta) is extremely rare with asymptomatic infection. Routine prenatal care doesn't typically change based on asymptomatic HSV-1 alone.

**At delivery:**
The main concern is neonatal herpes from contact during vaginal birth. However, with asymptomatic HSV-1:
- Risk of transmission is low (estimated <1% without active lesions or prodromal symptoms)
- Many providers support vaginal delivery without intervention
- Cesarean delivery is typically reserved for *active* lesions or prodromal symptoms at labor onset
- Antiviral prophylaxis (acyclovir) in the third trimester may be offered as a precaution, though evidence for asymptomatic HSV-1 is less robust than for HSV-2

**After birth:**
Newborn risk remains low; careful hygiene (hand-washing, avoiding direct contact if any lesions appear) is standard precaution.

**Critical next step:** Discuss your specific situation with your OB/GYN *before* or early in pregnancy. They'll review your serology, symptom history, and individualize your care plan. This conversation ensures informed, personalized decision-making.
