If you have no cold sores around or in your mouth can kiss someone?

While it's generally safe to kiss someone if you don't have any visible cold sores, it's important to note that the herpes simplex virus (HSV-1), which causes cold sores, can still be transmitted even in the absence of visible lesions. The virus can be present and shed from the body without causing any symptoms, a condition known as asymptomatic shedding.

Transmission can still occur during asymptomatic shedding, though the risk is lower compared to when there are active cold sores. It's important to practice safe kissing habits, such as avoiding contact with the mouth or face if you know or suspect you have the herpes simplex virus.

Additionally, it's crucial to communicate openly with your partner about your cold sore history and any potential risks. If you're concerned about transmission or have any questions about cold sores, it's always a good idea to consult with a healthcare professional. They can provide guidance and advice based on your specific situation.
