Abstain from sexual activity while lesions or prodromal symptoms are present
Patients with genital herpes should refrain from intercourse until all lesions have completely healed and any prodromal symptoms (tingling, burning, itching) have resolved. This is the consistent recommendation across CDC guidelines 122.
Clinical Algorithm for Sexual Activity Resumption
During Active Outbreak:
- Complete abstinence required when any of the following are present:
- Visible lesions (vesicles, ulcers, or crusts)
- Prodromal symptoms (tingling, burning, pain in genital area)
- Any skin breakdown or incomplete healing
When to Resume:
- Only after complete clinical resolution:
- All lesions fully healed (re-epithelialized)
- No crusting or scabbing remains
- No prodromal symptoms
- Skin integrity completely restored
Timeline Expectations:
- First episode: Typically 7-10 days with treatment, but may extend longer 22
- Recurrent episodes: Usually 5 days with early treatment 22
- Without treatment: Lesions may persist 2-3 weeks
Critical Caveats
Asymptomatic viral shedding occurs even when no lesions are present 12. This means:
- Transmission can occur between outbreaks
- Condom use should be encouraged during all sexual activity with uninfected partners 22
- Suppressive antiviral therapy reduces (but does not eliminate) asymptomatic shedding and transmission risk 2
HSV-2 sheds more frequently than HSV-1, particularly in the first 12 months after infection 22. Patients should be counseled that even with complete lesion healing, some transmission risk persists.
Risk Reduction Strategies Beyond Abstinence During Outbreaks:
- Daily suppressive therapy (valacyclovir, famciclovir, or acyclovir) for patients with frequent recurrences 22
- Consistent condom use (reduces but does not eliminate transmission)
- Partner disclosure and education
- Consider suppressive therapy specifically to reduce transmission to uninfected partners
The guideline is unambiguous: no sexual contact during any symptomatic period, resuming only after complete healing 122.
