There are things you can do at home to help manage herpes sores.
The following may reduce the risk of spreading the herpes simplex virus:
Oral herpes (herpes simplex type 1)
If you have sores on your face:
If you have tingling, burning, itching, or tenderness where you had a herpes sore, keep that area of your body away from others.
You can prevent spreading the sores to other parts of your body by:
Genital herpes (herpes simplex type 2)
When you have sores or symptoms do not have sex with uninfected partners.
If you do not have sores or symptoms, use a latex condom to lower the risk of spreading the virus. You should know that even with a condom, it is possible to spread the virus if it lies on nearby skin that the condom does not cover.
If you are pregnant tell your doctor if you or your partner has genital herpes. You may need to take medicine at the end of your pregnancy to prevent passing the virus to your baby.
