Genital herpes is caused by two types of viruses, herpes simplex (HSV) type 1 and type 2, which create cold sores.
Symptoms of genital herpes
The symptoms of genital herpes can be mild or severe, characterized by a blister or sore developing around the genitals or rectum. The blisters break, leaving a sore, which could take a week or two to heal. If you have had sexual contact with a person with herpes, you may have the infection, whether you have symptoms or not. A blood test will reveal if you are infected.
