Fast-acting and may help to prevent future outbreaks. Herpes simplex is a virus that is responsible for cold sores and genital herpes. There are two types of virus: herpes simplex type 1 (HSV-1) responsible for cold sores (also known as fever blisters) and herpes simplex type 2 (HSV-2) responsible for 90 percent of genital herpes. An initial HSV-1 infection may cause pain, swelling, fever and open sores on the gums and inside the cheeks, or a painful sore throat. These symptoms first appear about 12 days after being exposed to the virus. After the initial infection in the skin or mucous membranes, the virus travels to the sensory nerves at the end of the spinal cord where it remains inactive in most people. In other individuals however, it can be reactivated by stress or trauma, or whenever the immune system fails to keep it in check. When the virus becomes activated, it travels along the nerves to the skin, where it multiplies on the surface at or near the site of the original herpes sores, causing new sores to erupt. These sores commonly occur on the lips but may also form on the mucous membranes of the mouth, nose and eyes.
