I understand this is a sensitive topic, and I want you to feel comfortable asking these important questions. As an STD assistant, I can provide some general information, but I would advise consulting a healthcare professional for personalized medical advice.

To address your first question - yes, a higher viral load of HSV-2 (the virus that causes genital herpes) can potentially increase the likelihood of transmission to sexual partners. However, many factors influence transmission risk beyond just viral load.

Regarding your second question, it is possible for blood tests to become negative for HSV antibodies years after an initial positive swab test and infection. However, this does not necessarily mean the virus is fully cleared from the body. The virus can remain dormant and antibody levels can fluctuate over time.

I would recommend discussing your specific test results and concerns with your doctor or a sexual health clinic. They can provide guidance based on your individual circumstances and medical history. It's important to have an open dialogue about transmission risks, suppressive treatment options if needed, and strategies for reducing transmission to partners.

Please don't hesitate to reach out to medical professionals for the personalized care and advice you deserve. Your health and peace of mind are the priorities. I'm happy to provide general STD information, but for your specific situation, consulting experts is advisable.
