How Is Herpes Type 2 Transmitted? HSV-2 Infection Routes Explained

Question

My friend’s situation. He went to the hospital today and was told it might be stage 2. He currently has blisters on his genital area. He has been in a relationship with his girlfriend for 5 months.

1. Is it possible that he was already infected and is only now developing blisters? I heard the incubation period is about 4–10 days.

2. Or could it be that his girlfriend is an asymptomatic carrier, and he got infected and is now showing symptoms? We’re really curious. Neither of them has had this before, and his girlfriend has no symptoms.

3. Even if his girlfriend has no symptoms, should she still go to the hospital for testing?

4. If there are blisters present, sexual activity is not possible, right? Even though it seems obvious.

Hello, this is Dr. Ryu Kyung-ho from Goldman Urology Clinic, Gangnam Branch.

The incubation period for herpes typically ranges from 2 to 20 days. However, it is also common for individuals to remain asymptomatic for months or even years before experiencing their first outbreak. In your case, it is possible that a previously acquired virus has reactivated and presented as blisters due to a weakened immune system.

Additionally, herpes can be transmitted through sexual contact even when a partner is an asymptomatic carrier. Therefore, even if your girlfriend does not currently have symptoms, it is difficult to rule out the possibility of infection. It is important for both of you to visit a clinic together and undergo appropriate testing, such as antibody tests, to confirm your status.

During the period when blisters are present, the risk of transmission is high, and sexual activity should be avoided. Even after symptoms resolve, the virus can remain dormant in the body, so continued caution is necessary.

At our urology clinic, each branch is equipped with extensive clinical experience. We carefully evaluate each patient’s symptoms and overall health to provide accurate diagnoses and personalized treatment plans.

Identifying the exact cause is the first step toward effective treatment. If your symptoms persist, we strongly recommend visiting a urology clinic. We hope this information is helpful. Thank you.
