Primary Care Management of Suspected HPV Infection

Initial Assessment and Diagnosis

Visual examination is the primary diagnostic method for genital warts, which are caused predominantly by HPV types 6 and 11, according to the Centers for Disease Control and Prevention 1
Biopsy is indicated only in specific circumstances: uncertain diagnosis, lesions unresponsive to standard therapy, worsening during therapy, immunocompromised patients, or pigmented/ulcerated lesions, as recommended by the Centers for Disease Control and Prevention 1
Type-specific HPV nucleic acid tests are not recommended for routine diagnosis or management of visible genital warts, as stated by the Centers for Disease Control and Prevention 1
Most genital warts are asymptomatic, but patients may experience pruritus, pain, tenderness, or friability, according to the Centers for Disease Control and Prevention 1

The Centers for Disease Control and Prevention recommends first-line treatments that can be administered in primary care, including cryotherapy with liquid nitrogen and patient-applied therapies such as podofilox 0.5% solution or gel, for external genital warts 2
For vaginal warts, the Centers for Disease Control and Prevention recommends cryotherapy with liquid nitrogen, avoiding the use of cryoprobe due to risk of vaginal perforation, and TCA or BCA 80-90% applied only to warts, repeated weekly if necessary 3
For urethral meatus warts, the Centers for Disease Control and Prevention recommends cryotherapy with liquid nitrogen and podophyllin 10-25% in compound tincture of benzoin, applied by a provider 3
For anal warts, the Centers for Disease Control and Prevention recommends cryotherapy with liquid nitrogen, TCA or BCA 80-90% applied only to warts, and management in consultation with a specialist for intra-anal warts 3

The Centers for Disease Control and Prevention states that HPV infection is very common, with most sexually active adults acquiring HPV at some point, and that most cases clear spontaneously without causing health problems 2
The Centers for Disease Control and Prevention notes that the types of HPV that cause genital warts (types 6 and 11) are different from the high-risk types that can cause cancer, and that treatment targets visible warts but does not eliminate the virus itself 2
The American College of Obstetricians and Gynecologists recommends that patients be informed that recurrence is common, approximately 30%, regardless of treatment method, and that correct and consistent condom use might reduce but does not eliminate transmission risk 2

The American College of Obstetricians and Gynecologists recommends that all women with suspected HPV infection should have cervical cancer screening, following standard age-appropriate guidelines for HIV-negative women and more frequent screening for HIV-positive women 4, 5
The Infectious Diseases Society of America recommends that women with abnormal Pap test results should be referred for colposcopy and directed biopsy 6

The Centers for Disease Control and Prevention recommends that imiquimod, podophyllin, and podofilox should not be used during pregnancy, and that many experts advocate removal of genital warts during pregnancy as they can proliferate and become friable 4
The Infectious Diseases Society of America notes that immunocompromised patients may not respond as well to therapy, may have more frequent recurrences, and are at higher risk for squamous cell carcinomas arising in or resembling genital warts, and that HIV-infected patients with HPV infection are at increased risk for anal dysplasia and cancer 4, 6

The Centers for Disease Control and Prevention recommends HPV vaccination for all females aged 9-26 years, all males aged 9-21 years, and males aged 22-26 years if not vaccinated at younger ages, as stated by the Advisory Committee on Immunization Practices 6

The American College of Obstetricians and Gynecologists recommends referral to OB-GYN for women with abnormal cervical cytology, patients with cervical warts, patients with extensive or treatment-resistant warts, patients with intra-anal warts, and immunocompromised patients with concerning lesions 2, 3, 6

The Centers for Disease Control and Prevention advises against assuming HPV infection indicates sexual infidelity, as the virus can remain dormant for long periods, and against using HPV DNA testing for screening in men, partners of women with HPV, adolescent females, or for conditions other than cervical cancer 2
The American College of Obstetricians and Gynecologists recommends against performing cesarean delivery solely to prevent HPV transmission to newborns, and against using acetic acid soaks as a screening test for subclinical HPV infection due to high false-positive rates 4
