It's great that you're proactive about your health. The negative blood test result for herpes is indeed a positive sign, but it doesn't necessarily mean the virus has completely disappeared from your body. Sometimes, the virus can become dormant and not show up in tests.

Herpes infections are typically lifelong as there isn't a definitive cure yet. It's possible that at this moment, viral levels are undetectable due to various factors like immune response or testing sensitivity.

For accurate information regarding your specific case and to address any concerns or queries you have relating to this change in results after 20 years of diagnosis with HSV2, I recommend consulting with healthcare professionals who specialize in sexual health such as an infectious disease specialist or gynecologist familiar with herpes management.

If needed support resources on living well despite having herpes may be beneficial; feel free also seek out counseling services specializing in STIs/STDs if emotional distress surfaces surrounding these developments.
