Herpes Simplex Virus type 1 (HSV-1) is a common virus that primarily causes cold sores around the mouth and lips. It spreads easily through close contact, such as kissing or sharing utensils. While many people may carry the virus without showing symptoms, it can still be transmitted to others. In some cases, HSV-1 can also lead to genital herpes, especially through oral sex. Although there is no cure for HSV-1, antiviral medications can help manage outbreaks and reduce the risk of transmission. Practicing good hygiene and avoiding contact during outbreaks can also help prevent spreading the virus.
