The chances of getting infected with herpes simplex virus during an encounter highly depend on a lot of factors, which include the number of times you engage in sex and the frequency of using condoms when engaging sexual contacts.
It will also depend on how long your sex partner got the virus. The reason for this inquiry is because an individual who got infected with the human alphaherpesvirus for a long time has lesser chances of passing the disease to anyone, as it becomes less contagious compared to people who just got infected by the virus.
A recent study shows that other partners in five to ten percent of the couples get infected with herpes within a year, and these people seldom use condoms when they make interactions, and if they did, only when there’s an outbreak of cold sores or blisters. Hence, you should use a condom whenever you engage in contact sexually with your partner who has herpes, especially when the symptoms are visible to minimize the possibility of having it.
