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 risk of transmission to sexual partners. However, it's important to note that even with an undetectable viral load, transmission is still possible.

Regarding your second question, it is possible for the HSV-2 antibodies to become undetectable in a blood test over time after an initial positive swab test, especially if you haven't had any recent outbreaks. However, this doesn't necessarily mean the virus has been eliminated from your body.

I would recommend discussing your specific situation and concerns with your doctor or a sexual health clinic. They can order the appropriate tests, interpret the results accurately based on your medical history, and provide guidance on managing your condition and reducing transmission risks.

Remember, having an open conversation with your healthcare provider and potential sexual partners is crucial for making informed decisions about your sexual health. There are also support groups available if you need additional emotional support or resources.
