AI Answers About Warts: Model Comparison
DISCLAIMER: AI-generated responses shown for comparison purposes only. This is NOT medical advice. Always consult a licensed healthcare professional for medical decisions.
Warts are among the most common skin conditions, caused by the human papillomavirus (HPV). They affect ~10% of the global population, with children and young adults being particularly susceptible — ~33% of school-age children have warts at any given time. Common warts (verruca vulgaris) appear most frequently on hands and fingers, while plantar warts affect the soles of the feet. Though generally benign, warts can be persistent, painful, and cosmetically distressing. Their prevalence and the wide range of available treatments drive substantial online search volume, making AI accuracy on this topic highly relevant.
The Question We Asked
“I have several small, rough bumps on my fingers that I think are warts. They’ve been there for about four months and seem to be spreading. I’ve tried over-the-counter salicylic acid patches for two weeks but they don’t seem to be working. Are there better treatments? Can I spread them to other people?”

What Each Model Got Right
GPT-4
Strengths: GPT-4 correctly explained that warts are caused by HPV and are contagious through direct contact and shared surfaces. It provided a good overview of treatment options including salicylic acid, cryotherapy, and duct tape occlusion. It accurately noted that salicylic acid treatments typically require 8-12 weeks of consistent use for effectiveness.
Claude 3.5
Strengths: Claude delivered the most thorough response, explaining that two weeks of salicylic acid treatment is insufficient and that most OTC treatments require persistent daily application for two to three months. It covered a comprehensive range of treatments from OTC options to prescription immunotherapy (imiquimod) and in-office procedures. It also correctly noted that ~65% of common warts resolve spontaneously within two years.
Gemini
Strengths: Gemini provided practical tips about proper salicylic acid application technique, including soaking the area first and filing down dead skin between treatments. It correctly mentioned that warts are contagious and offered hygiene advice to prevent spreading.
Med-PaLM 2
Strengths: Med-PaLM 2 offered a clinically organized approach to wart treatment, presenting a stepped care model from conservative OTC treatments through in-office procedures. It correctly noted that immunocompromised individuals may experience more persistent and widespread warts requiring aggressive treatment.
What Each Model Got Wrong or Missed
GPT-4
- Did not adequately explain proper salicylic acid application technique
- Failed to mention that wart viruses can persist on surfaces like shower floors and gym equipment
- Did not discuss the role of the immune system in wart clearance
Claude 3.5
- Could have mentioned specific HPV strains responsible for common warts (HPV 2, 4, 27)
- Did not discuss the emotional and social impact of visible warts, particularly in children
Gemini
- Overstated the effectiveness of duct tape occlusion, which has mixed evidence in clinical trials
- Did not mention that genital warts are caused by different HPV strains and require different management
- Failed to discuss when warts might indicate an immune system problem
Med-PaLM 2
- Response was too clinical and lacked practical self-care guidance
- Did not mention prevention strategies beyond general hygiene
- Failed to address the contagiousness question directly enough
Red Flags All Models Should Mention
While warts are generally harmless, certain situations warrant medical attention:
- Warts on the face or genitals — require professional treatment and different approaches
- Rapidly spreading or multiplying warts — may indicate immune system compromise
- Warts that bleed, change color, or look unusual — should be evaluated to rule out other conditions
- Warts in immunocompromised individuals — may be more aggressive and harder to treat
- Painful plantar warts that interfere with walking — may need professional intervention
- Lesions that do not respond to months of treatment — may not actually be warts
When to Trust AI vs. See a Doctor
AI Is Reasonably Helpful For:
- Understanding what causes warts and how they spread
- Learning about OTC treatment options and proper application techniques
- Getting general prevention and hygiene advice
- Understanding that most warts are harmless and often resolve on their own
- Learning about the typical timeline for treatment effectiveness
See a Doctor When:
- Warts appear on the face, genitals, or around nails
- Home treatment has been tried consistently for three months without improvement
- Warts are spreading rapidly despite treatment
- You have diabetes and develop plantar warts (risk of foot complications)
- You are immunocompromised and developing warts
- You are unsure whether a skin growth is actually a wart
- Warts are causing significant pain or functional impairment
Methodology
Each AI model received the identical patient scenario prompt. Responses were evaluated by the mdtalks editorial team using our standardized evaluation framework, which assesses factual accuracy against current dermatology guidelines, completeness of safety warnings, readability for a general audience, and appropriateness of the recommendation to seek professional care. Scores reflect composite ratings across these dimensions.
Key Takeaways
- Claude 3.5 scored highest (8.7) for its comprehensive treatment information and realistic timeline expectations
- All models correctly identified warts as HPV-related and contagious, but varied in practical treatment guidance
- The most common user mistake — giving up on salicylic acid too early — was best addressed by Claude and Gemini
- No AI model should be used to diagnose skin growths; visual examination by a professional is important
- Gemini scored lowest (7.2) partly due to overstating evidence for some alternative treatments
