Herpes simplex is a common viral infection caused by the herpes simplex virus (HSV). There are two main types: HSV-1, which typically causes oral herpes, and HSV-2, which usually leads to genital herpes. The virus can remain dormant in the body and may reactivate, leading to outbreaks characterized by blisters or sores. Transmission occurs through direct contact with an infected person, often during intimate activities or through kissing. While there is no cure for herpes simplex, antiviral medications can help manage symptoms and reduce the frequency of outbreaks. Practicing safe behaviors can lower the risk of spreading the virus.
