Herpes on Shared Utensils: Why Soap and Water Isn’t Enough for Disinfection

Washing a spoon with soap and water does not reliably inactivate herpes simplex virus (HSV-1). HSV can survive on fomites for hours. Effective disinfection requires:

• Heat – Dishwasher “sanitize” cycle (≥70°C / 158°F) or boiling ≥1 minute.
• Chemical disinfectants – EPA-registered virucides (bleach 1:100, 70% ethanol, 0.5% hydrogen peroxide) with appropriate contact time.
• Dedicated utensils – Simplest prevention during active outbreaks.

Transmission via shared utensils is possible but low-risk compared to direct oral contact. However, immunocompromised individuals or neonates warrant strict avoidance of shared items during outbreaks.
