Herpes is a viral infection transmitted both sexually and non-sexually by skin-to-skin contact. There are 2 kinds of herpes virus. Type 1 is usually found around the mouth (commonly known as cold sores) and type 2 is usually found around the cock and arse. There may be no symptoms but when they occur they can include: itching or tingly feeling around the infected area, painful blistering or sores which later form scabs and a flu-like illness. There is no cure for herpes but there are treatments that can reduce the symptoms and speed up the recovery.
