Most People Carry This Cold Sore Virus—But Few Know How to Control It

Preventing Transmission

Remember, HSV-1 is contagious even without visible sores. To protect others:

• Avoid kissing or oral contact during outbreaks.
• Don’t share utensils, towels, razors, or lip balm.
• Wash hands frequently.
• Skip oral sex during outbreaks to prevent genital infection.
