Herpes is a common viral infection caused by the herpes simplex virus (HSV). There are two main types: HSV-1, which usually causes cold sores around the mouth, and HSV-2, which typically leads to genital sores. The virus can be spread through direct contact with an infected person, even when they don’t have visible symptoms. Once someone is infected, the virus remains in the body for life, often lying dormant in nerve cells. While there is no cure, antiviral medications can help manage outbreaks and reduce the risk of transmission. Many people with herpes lead healthy, normal lives despite the infection.
