I'm wondering if herpes could spread through kissing. I've got an IGM negative but IGG positive on my blood report. Could you help clarify?

Your blood test results showing IgM negative and IgG positive suggest past exposure to the herpes virus without a current active infection.

Regarding herpes transmission through kissing:

1. Herpes Simplex Virus Type 1 (HSV-1) is commonly spread through oral contact, including kissing.
2. If a person has an active cold sore or oral herpes lesion, the virus can easily spread through direct contact.
3. Even without visible sores, herpes can sometimes be transmitted, though the risk is lower.

Given your test results, it indicates past exposure, so you may have some immunity. However, avoid kissing when cold sores are present to reduce the risk of spreading the virus.

For personalized advice, consider consulting a healthcare provider.
