Herpes transmission


Doctor, I would like to ask, after experiencing recurrent cold sores twice, I have a red patch on my lip that has been persistent (in different locations).
Initially, it was itchy, and later I consulted a dermatologist and applied medication, but the red patch remains and shows no signs of developing blisters.
I didn't pay much attention to it, but after deep kissing my boyfriend yesterday, I noticed today that it seems to be developing small blisters.
Is this contagious to my boyfriend? Also, if we share blankets and pillows (with contact to the mouth), is there a risk of transmission?

Hello: The information provided here is for reference.
If it is herpes simplex, the situation you described could potentially be contagious.
Regarding sharing blankets and pillows (if they come into contact with the mouth, can it be transmitted? --> If there are secretions, it is still possible, although not directly, and the chances are low.
Wishing you good health.

More Info


Herpes simplex virus (HSV) is a common viral infection that can cause oral and genital herpes. Understanding the transmission risks associated with herpes is crucial, especially in intimate relationships.
Firstly, it’s important to recognize that HSV can be transmitted even when there are no visible symptoms, a phenomenon known as asymptomatic shedding. This means that the virus can still be present on the skin and can be transmitted to a partner through direct contact, even if there are no active sores or blisters.

In your case, since you have a history of recurrent cold sores (oral herpes), the risk of transmission to your boyfriend during deep kissing is present, especially if you are experiencing prodromal symptoms (such as itching or tingling) or if you notice the development of small blisters. The presence of a red, itchy area on your lip could indicate that the virus is reactivating, which increases the likelihood of shedding and potential transmission.

Regarding your specific questions:
1. Kissing and Transmission: If you notice that small blisters are starting to form, it is advisable to avoid intimate contact, including kissing, until the sores have completely healed. The risk of transmission is highest when active lesions are present, but as mentioned, the virus can still be transmitted even when sores are not visible.

2. Sharing Bedding and Personal Items: Sharing items such as pillows and blankets can pose a risk of transmission, particularly if the infected area comes into contact with these items. While the virus does not survive long on surfaces, it can still be transmitted through direct contact with contaminated items. It is best to avoid sharing personal items like towels, lip balm, or utensils during an outbreak or when symptoms are present.

3. Precautions: To minimize the risk of transmission in your relationship, consider the following precautions:
- Avoid intimate contact during outbreaks or when you feel an outbreak is imminent (e.g., during the prodromal phase).

- Discuss your herpes status openly with your partner to ensure they are informed and can take precautions as well.

- Consider using antiviral medications, which can help reduce the frequency of outbreaks and lower the risk of transmission.

- Practice good hygiene, such as washing your hands after touching the affected area and avoiding touching your face.

4. Consulting a Healthcare Provider: Since you have persistent symptoms and concerns about transmission, it would be wise to consult a healthcare provider. They can provide a proper diagnosis, recommend appropriate treatment, and offer guidance on managing outbreaks and reducing transmission risks.

In summary, while the risk of transmitting herpes is present, especially during active outbreaks, taking precautions can significantly reduce the likelihood of transmission. Open communication with your partner and consulting with a healthcare professional are key steps in managing your health and relationship effectively.
