Herpes Simplex Virus Infections
Herpes simplex virus infections are common and can cause painful blisters or ulcers. The virus spreads by skin-to-skin contact and is treatable but not curable.
Key points
- Cold sores typically begin with an itchy, tingling feeling, then form small, painful, fluid-filled blisters that usually crust over and heal within a few days.
- An estimated 3.8 billion people under age 50 (64% globally) have HSV-1 infection, the main cause of oral herpes.
- Antiviral medicines can reduce the duration and severity of outbreaks, and treatment is most effective when started within 48 hours of symptom onset.
