Herpes Simplex Virus (HSV) Infection

Overview of Herpes Simplex Virus

• Types of HSV:

  • HSV-1: Commonly causes oral herpes, leading to cold sores around the mouth and face. Most people contract it during childhood. CDC on HSV-1
  • HSV-2: Primarily responsible for genital herpes, affecting the genitals, buttocks, or anal area. It's a sexually transmitted infection (STI).

• Transmission:

  • HSV-1: Spread through respiratory droplets or direct contact with infected saliva.
  • HSV-2: Transmitted via genital contact. WHO on HSV

• Prevalence:

  • By adulthood, up to 90% of people have antibodies to HSV-1.
  • HSV-2 affects 5-20% of the population, with men being 20% more likely to experience recurrences than women.

Symptoms and Complications

• Symptoms:

  • Painful, watery blisters on the skin or mucous membranes.
  • Blisters heal with a scab, similar to chickenpox lesions.

• Complications:

  • Herpes Simplex Encephalitis: A severe condition caused by the virus reaching the central nervous system.
  • Neonatal Herpes: Occurs when a newborn acquires the virus from the mother during birth.
  • HSV Meningitis: Inflammation of the protective membranes covering the brain and spinal cord.

Treatment Options

• Antiviral Medications:

  • Aciclovir (Zovirax) and Valaciclovir: Commonly prescribed to control outbreaks.
  • Famciclovir: Another option with improved oral bioavailability.

• Alternative Treatments:

  • Docosanol (Abreva): Over-the-counter treatment for cold sores.
  • Tromantadine: Effective against herpes.
  • Lactoferrin: Found in whey protein, enhances the effect of aciclovir.
  • Roscovitine: Inhibits viral genome transcription.
  • Aloe Vera: May provide relief for genital herpes.

Perspectives on HSV

• Medical Perspective:

  • HSV is a lifelong infection with no cure, but antiviral treatments can manage symptoms and reduce transmission risk.
  • Vaccines are under development but not yet available.

• Public Health Perspective:

  • Education on safe practices and early diagnosis is crucial to prevent the spread.
  • Stigma around herpes can hinder open discussions and treatment-seeking behavior.

Interesting Facts

• Approximately 90% of HIV-positive individuals are seropositive for HSV-1, and about 77% for HSV-2. NIH on HSV and HIV
• Cimetidine, a heartburn medication, has shown potential in reducing the severity of herpes outbreaks.
