How to Prevent Spreading Cold Sores
The oral herpes virus is spread through direct skin-to-skin contact. It is even contagious when you can’t see a cold sore. Most people first contract the cold sore virus (HSV-1) when they are very young, usually by skin-to-skin contact with an adult carrying the virus.1 The virus can spread in various ways: through kissing, or by sharing objects like toothbrushes, water bottles, drinking glasses, and silverware.2 It is also possible to spread the virus from the mouth to the genitals, eyes, and other parts of the body.
If you think you might have oral herpes but are unsure, please speak to a healthcare professional about getting diagnosed. They can identify whether or not you carry the oral herpes virus (HSV-1) through signs, symptoms, and your medical history.2
