Herpes Transmission Risk: Understanding HSV-1 and HSV-2

Herpes transmission risk depends on virus type, exposure route, and immune status.

Virus Types

• HSV-1: Usually oral herpes (cold sores); lower transmission risk (thicker lip skin).
• HSV-2: Usually genital herpes; higher transmission risk (thinner genital skin).

Transmission Routes

• Direct contact with sores/lesions (kissing, sharing utensils, oral/genital sex).
• Indirect contact (contaminated objects) – less common.

Immune Status

Weakened immune systems (HIV/AIDS, chemotherapy) increase susceptibility.

Prevention

• Avoid contact with visible sores.
• Use condoms during sex.
• Don't share drinks/utensils.
• Wash hands frequently.
• HSV-2 vaccination (Gardasil 9) available.

Any sexual activity carries infection risk; practice safe sex to reduce transmission.
