HPV and Genital Herpes Prevention and Treatment

Prevention Strategies

  • The American College of Physicians recommends vaccination as the cornerstone of HPV prevention, with routine immunization recommended for all males and females aged 11-12 years, as it prevents approximately 90% of cervical and other HPV-related cancers 1
  • The Centers for Disease Control and Prevention suggests that condom use reduces HPV infection risk by approximately 70% when used consistently and correctly 1
  • The American College of Obstetricians and Gynecologists states that suppressive antiviral therapy in infected partners reduces transmission to serodiscordant partners 2, 3
  • The Centers for Disease Control and Prevention recommends that condom use during all sexual exposures with new or uninfected partners reduces transmission risk 3

Screening Approaches

  • The American College of Obstetricians and Gynecologists recommends that all women should have Pap test screening within 3 years of sexual activity or by age 21 years, whichever comes first 1
  • The American Cancer Society suggests that women aged >30 years with three consecutive normal Pap tests should be screened every 2-3 years 1
  • The Centers for Disease Control and Prevention states that routine serologic screening is NOT recommended in asymptomatic individuals with low pretest probability 3

Treatment Differences

  • The American College of Physicians recommends that HPV infections themselves are not treated; only HPV-associated lesions are managed 5
  • The Centers for Disease Control and Prevention suggests that treatment options for cervical, vaginal, and vulvar precursors include cryotherapy, electrocautery, laser therapy, and surgical excision 1
  • The American Academy of Dermatology states that genital warts can be treated with topical pharmacologic agents including imiquimod 3.75% cream 1
  • The Infectious Diseases Society of America recommends that first clinical episode of genital herpes should be treated with valacyclovir 1 g orally twice daily, acyclovir 400 mg orally three times daily, or famciclovir 250 mg orally three times daily for 7-10 days 3

Special Clinical Scenarios

  • The American College of Obstetricians and Gynecologists recommends that suppressive-dose acyclovir starting at week 36 prevents HSV recurrences requiring cesarean delivery 6, 7
  • The Centers for Disease Control and Prevention suggests that HIV-infected individuals should receive 3-dose HPV vaccination series at ages 11-12 years or catch-up through age 26 if not previously vaccinated 1

Critical Distinctions in Natural History

  • The American College of Physicians states that genital HSV-1 has less shedding and fewer recurrences compared to HSV-2, particularly after the first year 4, 7
  • The Centers for Disease Control and Prevention recommends that approximately 60% of individuals exposed to HSV-2 do not develop symptoms, yet can still transmit the virus 8, 9

Common Pitfalls

  • The American College of Obstetricians and Gynecologists recommends that neither routine surveillance for HPV infection nor partner notification is useful for prevention, as the majority of partners are already infected 1
  • The Infectious Diseases Society of America states that suppressive therapy for genital HSV-1 has not been shown to reduce transmission to sexual partners 4, 7
