Hello. I am Dr. Sang-ju Lee, a dermatologist.
Among the diseases that cause small, clustered blisters are herpes simplex and herpes zoster. Both diseases are similar in that they cause pain and blisters, leading many people to confuse them, but they are distinctly different conditions. It is known to be very difficult for anyone other than a doctor to distinguish between them. Today, I will explain in detail how to differentiate between the two diseases, as well as various questions related to herpes simplex.
What is the difference between herpes simplex and herpes zoster?
The names are different!
Herpes simplex is called Herpes Simplex in English, and herpes zoster is called Herpes Zoster. The two diseases have similarities, like cousins, but clinically they differ in symptoms, appearance, and the areas where they occur.
How to distinguish by symptom area
- Herpes simplex: Blisters primarily cluster around the mouth or on one area of the skin. Some people may experience recurrent outbreaks in specific areas of the body, such as around the genitals or buttocks, but it does not spread from one area to another.
- Herpes zoster: It is characterized by blisters appearing in a band-like pattern along one side of the skin. It does not occur simultaneously on both sides of the skin, but rather appears sparsely in a band shape on one side.
Difference in recurrence
- Herpes simplex: Recurrence is frequent. When one is tired or has a weakened immune system, it tends to reappear in the same area where the rash previously occurred.
- Herpes zoster: This disease occurs once or twice in a lifetime, and recurrence is not as common as with herpes simplex.
Why does herpes simplex occur and how is it treated?
Herpes simplex is caused by the herpes simplex virus. The first step in treatment is to use antiviral medication.
- A sufficient amount of oral antiviral medication is required.
- If oral administration is difficult, topical antiviral medications can also be used.
Can herpes simplex be transmitted?
Yes, herpes simplex can be transmitted between people. The reason we often get herpes simplex around the mouth is often due to the virus being transmitted through contact with others. In particular, a person carrying the herpes simplex virus can transmit the virus through contact, such as kissing a baby. In this case, the baby may develop herpes simplex in the affected area every time they are tired for the rest of their life, so caution is needed when in contact with babies or others.
If you have herpes simplex, you must be especially careful when in contact with babies or others.
Can herpes simplex recurrence be prevented?
Herpes simplex tends to recur when the body is tired. Therefore, it is important to pay attention to overall health management. If you feel unusual symptoms before herpes simplex recurs, you can take antiviral medication quickly to manage the symptoms relatively easily.
So far, we have learned about herpes simplex. Herpes simplex and herpes zoster are similar yet different diseases, and accurate distinction and appropriate management are important. If you have any questions, we recommend consulting a medical professional.
