To prevent transmission of the virus to another person, avoid:

• Intimate physical contact with others
• Sharing eating utensils, toothbrushes, towels and razors
• Touching the blisters (always wash your hands after applying medication)

How to minimize recurrent outbreaks:

• Eat foods high in lysine (an amino acid found in red meats, fish and dairy products) or take supplements
• Apply sunscreen to the face and lips before going outdoors
• Shave with a disposable razor during an outbreak
• Replace your toothbrush
• Engage in relaxing activities to reduce stress
