Avoid oral activities such as kissing or oral sex when a cold sore is present. Cold sores are caused by the herpes simplex virus (HSV-1), which can be easily transmitted through direct contact. To prevent spreading, wait until the cold sore has fully healed—this typically means the scab has fallen off without raw skin left. Consult a healthcare provider for personalized advice.
