Introduction
- Genital herpes is a sexually transmitted infection (STI) caused by the herpes simplex virus (HSV), primarily types 1 and 2 (HSV-1 and HSV-2).
- It is a lifelong condition characterized by periodic outbreaks of painful blisters or sores in the genital area.
- While there is no cure, effective treatments can manage symptoms, reduce the frequency of outbreaks, and lower transmission risk.
Causes of Genital Herpes
- HSV-1 and HSV-2
- HSV-1: Traditionally causes oral herpes but increasingly responsible for genital infections.
- HSV-2: Primarily causes genital infections.
- Transmission
- Direct skin-to-skin contact during vaginal, anal, or oral sex.
- Can occur even when the infected person shows no symptoms (asymptomatic shedding).
- Risk Factors
- Multiple sexual partners.
- Inconsistent use of condoms or barriers.
- Weakened immune system.
Symptoms of Genital Herpes
- Primary Infection
- Painful blisters or ulcers on the genitals, anus, or thighs.
- Swollen lymph nodes, fever, and body aches.
- Burning or itching sensation before blisters appear.
- Recurrent Episodes
- Milder symptoms with fewer sores.
- Triggers include stress, illness, menstruation, or sun exposure.
- Asymptomatic Cases
- Many individuals remain unaware they are infected.
Complications of Genital Herpes
- Neonatal Herpes: Severe infection in newborns exposed during delivery.
- Psychological Impact: Anxiety, depression, or stigma associated with diagnosis.
- Increased Risk of Other STIs: Herpes sores increase susceptibility to HIV.
- Urinary Retention: In rare cases, severe outbreaks may cause temporary urinary obstruction.
Diagnosis of Genital Herpes
- Physical Examination
- Identification of characteristic sores or blisters.
- Laboratory Tests
- Viral Culture: Detects HSV from fluid samples of sores.
- Polymerase Chain Reaction (PCR): Identifies HSV DNA; highly sensitive.
- Serology Tests: Detects antibodies to HSV-1 and HSV-2.
Treatment Options for Genital Herpes
1. Antiviral Medications
Medication | Brand Name | Manufacturer | Cost Range |
---|---|---|---|
Acyclovir | Zovirax | GSK | $10–$30 per pack |
Valacyclovir | Valtrex | GSK | $20–$50 per pack |
Famciclovir | Famvir | Novartis | $30–$60 per pack |
- Purpose: Reduce symptoms, shorten outbreaks, and suppress viral shedding.
- Dosing:
- Primary Outbreak: Higher doses for 7–10 days.
- Recurrent Outbreaks: Shorter 2–5 day courses.
- Suppressive Therapy: Daily low doses to prevent recurrences.
2. Supportive Care
- Pain Relief: Ibuprofen or paracetamol for discomfort.
- Warm Baths: Helps soothe sores and reduce irritation.
- Topical Treatments: Lidocaine gel to alleviate pain or itching.
3. Prevention of Transmission
- Barrier Methods
- Consistent use of condoms or dental dams reduces risk.
- Antiviral Suppression
- Daily antivirals lower the risk of transmitting HSV to partners.
- Avoid Sexual Activity During Outbreaks
- Reduces the likelihood of spreading the virus.
4. Lifestyle and Alternative Therapies
- Stress Management: Reduces recurrence frequency (e.g., yoga, meditation).
- Dietary Adjustments: Avoid trigger foods high in arginine (e.g., nuts, chocolate).
Monitoring Parameters
- Frequency and severity of outbreaks.
- Adherence to suppressive antiviral therapy.
- Periodic blood tests for serology in new partners or pregnancy.
Patient Counseling Points
- Reassure that genital herpes is a manageable condition with treatment.
- Educate on safe sexual practices to reduce transmission risk.
- Discuss potential triggers for outbreaks and strategies to avoid them.
- Encourage open communication with partners about HSV status.
Use in Children
- Neonatal herpes requires immediate antiviral treatment with intravenous acyclovir.
Use in Pregnancy
- Suppressive antiviral therapy in the third trimester reduces the risk of transmission.
- Cesarean delivery may be recommended if active lesions are present during labor.
Use in Elderly
- Ensure dosing adjustments for renal impairment; monitor for side effects like confusion.
