What are the symptoms of genital herpes?

Once exposed to the virus, there is an incubation period that generally lasts 3 to 7 days before a lesion develops. During this time, there are no symptoms and the virus cannot be transmitted to others. An outbreak usually begins within two weeks of initial infection and manifests as an itching or tingling sensation followed by redness of the skin. Finally, a blister forms. The blisters and subsequent ulcers that form when the blisters break, are usually very painful to touch and may last from 7 days to 2 weeks. The infection is definitely contagious from the time of itching to the time of complete healing of the ulcer, usually within 2-4 weeks. However, as noted above, infected individuals can also transmit the virus to their sex partners in the absence of a recognized outbreak.
