WebMD explains the two types of herpes simplex virus, including causes, symptoms, and treatment. Herpes simplex type 1, which is transmitted through oral secretions or sores on the skin, can be spread through kissing or sharing objects such as toothbrushes or eating utensils. In very rare cases HSV- 1 can spread spontaneously to the brain, causing herpes encephalitis, a dangerous infection that can lead to death. Usually the first herpes simplex virus that people encounter, oral HSV-1, is typically spread simply by the kind of social kiss that a relative gives a child. Herpes simplex is a common viral infection that presents with localised blistering. Type 2 HSV infections occur mainly after puberty, and are often transmitted sexually.
