Herpes simplex is a disease that affects the mouth or genital region, according to Medline Plus. Herpes simplex virus 1 begins in childhood, and affects the lips, face and mouth. Herpes simplex 2 is sexually transmitted, and leads to genital ulcers and sores.
Symptoms
Herpes simplex virus 1 and 2 differ in their symptoms. Symptoms of herpes simplex virus 1 include lesions in the mouth, cold sores and eye infections. This virus is passed through saliva. Symptoms of herpes simplex virus 2 include oral and genital sores obtained through sexual contact. Both types of herpes can lead to a brain infection called meningoencephalitis.
Diagnosis
A doctor can do a thorough physical exam to determine whether your lesions are herpes simplex virus 1 or 2. Sometimes, more specific tests are necessary. A blood test can look for antibodies in your blood that attack the herpes virus. A biopsy of the lesion can be obtained, and a direct fluorescent antibody test can be used to detect antibodies. A viral culture can detect the herpes infection.
Prevalence
According to the Dermatology Channel, 75 percent of people in the United States are exposed to herpes simplex virus 1 and 15 percent of people in the United States are exposed to herpes simplex virus 2.
Treatment
Sometimes treatment for herpes simplex virus 1 and 2 is not indicated if symptoms are mild. People that have recurrent symptoms can take antiviral medications.
Prognosis
Oral and genital lesions can heal in seven to 10 days. Sometimes it might last longer. The herpes infection stays in your body for life and can go through cycles of remission and flare-ups.
