If you get a cold sore once does that mean will have herpes for the rest of your life?

Getting a cold sore once does not necessarily mean you will have herpes for the rest of your life. Cold sores are caused by the herpes simplex virus (HSV-1), which is a common virus that many people carry. Once you have been infected with HSV-1, the virus lies dormant in your body and can be reactivated from time to time, causing cold sores to appear. While herpes is a lifelong infection, cold sores may not occur frequently in everyone. Some people may experience occasional outbreaks, while others may have them more frequently. The severity and frequency of cold sores can vary from person to person and can also be influenced by various factors such as stress, exposure to sunlight, hormonal changes, and immune system functioning. It's important to consult with a healthcare professional if you have concerns about herpes or cold sores.
