The index value for HSV-2 testing typically indicates the level of antibodies present in your blood, showing past exposure to the virus. An index value of 7.55 suggests a high likelihood of an active or recent infection with HSV-2.

Transmission risk is generally higher when there are visible symptoms like sores or blisters, but it's still possible to transmit even without evident signs (asymptomatic shedding). Using protection such as condoms and discussing this issue openly with your partner can help reduce transmission risks significantly.

It’s essential for both you and your partner to communicate openly about sexual health concerns and consider options like antiviral medication if needed. Consulting healthcare professionals for personalized advice on managing herpes outbreaks would be highly recommended in this situation.
