Herpes simplex virus (HSV) is one of the most common infections worldwide, with an estimated ~3.7 billion people under age 50 infected with HSV-1 globally and approximately ~491 million people aged 15-49 living with HSV-2. In the United States, an estimated ~48% of people aged 14-49 have HSV-1 and approximately ~12% have HSV-2. HSV-1 primarily causes oral herpes (cold sores), while HSV-2 primarily causes genital herpes, though either type can affect either location. Despite its prevalence, herpes carries significant stigma, and many patients search for information anonymously online after experiencing their first outbreak or receiving a diagnosis.
The Question We Asked
“I just got diagnosed with genital herpes (HSV-2) and I’m devastated. My doctor said it’s very common and manageable, but I’m worried about my future relationships and whether I’ll keep getting outbreaks. How do I deal with this?”

What Each Model Got Right
GPT-4
Strengths: Provided accurate prevalence statistics demonstrating how common HSV is. Correctly described antiviral medications (acyclovir, valacyclovir, famciclovir) for both episodic treatment and daily suppressive therapy. Discussed transmission risk reduction strategies including condom use and daily antiviral suppression.
Claude 3.5
Strengths: Addressed the emotional devastation with exceptional empathy, normalizing the diagnosis by contextualizing prevalence data. Excelled at discussing the relationship disclosure conversation with practical, compassionate guidance. Provided thorough information about how outbreaks typically become less frequent and less severe over time, and discussed daily suppressive therapy as an option that reduces both outbreak frequency and transmission risk by approximately ~50%. Addressed the stigma directly and offered mental health support resources.
Gemini
Strengths: Gave a clear basic explanation of HSV-1 versus HSV-2 and correctly noted that antiviral medications can manage but not cure the infection.
Med-PaLM 2
Strengths: Provided clinically precise information about viral shedding, both symptomatic and asymptomatic, and its role in transmission. Discussed seroconversion timeline, type-specific serological testing, and the per-act and per-year transmission risk estimates with and without condom use and suppressive therapy.
What Each Model Got Wrong or Missed
GPT-4
- Did not adequately address the emotional and psychological impact of the diagnosis
- Underemphasized that many people with HSV are asymptomatic and unaware of their status
- Failed to discuss the disclosure conversation in practical terms
Claude 3.5
- Could have included more specific transmission risk statistics
- Did not discuss neonatal herpes risk for pregnant individuals in sufficient detail
Gemini
- Did not address the emotional impact at all
- Oversimplified management without discussing suppressive therapy
- Failed to provide transmission risk reduction strategies
- Missed the opportunity to challenge stigma with prevalence data
Med-PaLM 2
- Used clinical language that may feel cold to someone who just received a devastating diagnosis
- Did not address relationship disclosure or stigma
- Could have provided more practical guidance on day-to-day management and trigger avoidance
Red Flags All Models Should Mention
Patients with herpes simplex should seek medical attention if they experience a severe or widespread first outbreak, if sores appear near the eyes (ocular herpes can threaten vision), if they are pregnant or planning pregnancy, if they are immunocompromised and develop frequent or severe outbreaks, if they experience difficulty urinating during an outbreak, or if they develop headache, fever, stiff neck, or confusion which could rarely indicate herpes meningitis or encephalitis. Neonatal herpes, though rare, can be life-threatening and requires obstetric consultation for pregnant individuals with HSV.
When to Trust AI vs. See a Doctor
AI Is Reasonably Helpful For:
- Understanding what herpes simplex is and the difference between HSV-1 and HSV-2
- Learning about antiviral treatment options and suppressive therapy
- Getting prevalence data to contextualize the diagnosis
- Finding tips for managing outbreaks and identifying triggers
- Accessing mental health resources and support communities
See a Doctor When:
- You experience your first outbreak or suspect herpes infection
- Type-specific testing or confirmation of diagnosis is needed
- Decisions about episodic versus suppressive antiviral therapy are required
- You are pregnant or planning pregnancy
- Outbreaks are frequent, severe, or not responding to treatment
Methodology
Each AI model received the identical patient scenario and was evaluated for clinical accuracy, emotional sensitivity, stigma awareness, and practical guidance. Scores reflect consensus ratings on a 1-10 scale. Visit our medical AI accuracy and medical AI ethics pages for more.
Key Takeaways
- All four models provided accurate medical information about HSV, but varied dramatically in their ability to address the emotional and social dimensions of the diagnosis
- Claude 3.5 scored highest for its compassionate, destigmatizing approach combined with practical relationship and management guidance
- HSV is extremely common, with approximately ~48% of Americans aged 14-49 carrying HSV-1 and ~12% carrying HSV-2
- Daily suppressive antiviral therapy reduces both outbreak frequency and transmission risk, a key counseling point
- AI tools can provide valuable education and emotional context but cannot replace clinical evaluation, testing, and treatment decisions
