Herpes simplex virus 1 (HSV-1) is a type of herpes virus that is a highly contagious pathogen that infects the oral and genital areas. It is primarily spread through oral-oral contact, such as kissing or sharing utensils, and can also be transmitted through sexual contact. Once a person is infected with HSV-1, the virus can remain dormant in the body for long periods of time and reactivate later in life, causing outbreaks of cold sores. There is no cure for HSV-1, but antiviral medications can help manage symptoms and reduce the frequency of outbreaks.
