Displaying item Herpes Simplex

Herpes simplex is an infection of the skin with the herpes simplex virus. There are two types of herpes virus, called herpes simplex type 1 and herpes simplex type 2. Herpes infection is caught from another person through contact with mouth, eye or genital secretions or through direct contact with an active lesion. Herpes simplex type 1 usually infects the mouth or eye and herpes simplex type 2 usually infects the genital area. After the virus infects the person, whether it shows on the skin or not, it goes to local sensory nerves and lies hidden (dormant) until reactivation (recurrence of the herpes infection). Reactivation can occur after a few weeks or even years, when the virus travels to the skin supplied by the nerve and appears as a blister or rash on the skin. The commonest areas to be affected by herpes simplex are the lips (as cold sores), and the genital area (as genital herpes). Genital herpes infection is usually a sexually transmitted disease.
