Primary Herpes Simplex Infection
Children can contract HSV-1 through close contact with an infected person. Common ways the virus spreads include:
- Kissing
- Sharing cups or utensils
- Sharing washcloths or towels
- Touching the cold sore before it heals
Once a child is infected, the virus remains dormant in the body and can reactivate, causing cold sores. Triggers for reactivation include exposure to hot sun, cold wind, illness, and a weakened immune system.
