Can a 1cm Asymptomatic Vulvar Wart Be Transmitted to a New Partner?
Yes, this elderly patient can transmit HPV to a new partner—genital warts are transmissible even when asymptomatic, and transmission can occur even when no visible warts are present. 1
Transmission Risk
The CDC explicitly states that genital warts can be transmitted to others even when no visible signs of warts are present, and even after warts are treated. 1 This means:
- The presence or absence of symptoms is irrelevant to transmission risk 1
- The size of the wart (1cm in this case) does not eliminate infectivity 1
- HPV transmission occurs primarily through direct skin-to-skin or skin-to-mucosa contact during sexual activity 2, 3
- Within an ongoing sexual relationship, both partners are usually already infected by the time one person is diagnosed, even if signs of infection are not apparent 1, 4
Critical Counseling Points for This Patient
She should inform her current or new sexual partner(s) that she has genital warts, as they can be transmitted to others. 1 The CDC recommends:
- She should refrain from sexual activity until the warts are gone or removed 1
- It is not known how long a person remains contagious after warts are treated 1
- Correct and consistent condom use can lower the chances of transmission, but is not fully protective because HPV can infect areas not covered by a condom 1
Management Considerations
Treatment should be offered even though the wart is small and asymptomatic, because:
- Treatment may reduce transmission risk by "debulking" visible warts, though no studies definitively prove this reduces HPV transmission 1
- If left untreated, genital warts may resolve spontaneously (20-30% within 3 months), remain unchanged, or grow 1
- Genital warts commonly recur after treatment, especially in the first 3 months 1
Partner Management
HPV testing is not recommended for her partner 1, 4, as:
- The CDC explicitly states HPV tests should not be used to screen men or partners of women with HPV 4
- No clinically validated HPV test exists for men 4
- Both partners should be screened for other STDs if one has genital warts 1
Common Pitfalls to Avoid
- Do not assume asymptomatic warts are non-infectious—transmission occurs regardless of symptoms 1
- Do not falsely reassure that condoms provide complete protection—they reduce but do not eliminate risk 1
- Do not delay counseling about transmission risk while awaiting treatment 1
- A diagnosis of HPV does not indicate sexual infidelity, as HPV can remain dormant and reactivate years after initial infection 1, 4
