"HSV-1 and HSV-2 can be found in and released from the sores that the viruses cause, but they also are released between outbreaks from skin that does not appear to be broken or to have a sore. Most genital herpes is caused by HSV-2. A person almost always gets HSV-2 infection during sexual contact with someone who has a genital HSV-2 infection but may not know that they are infected and may not have a visible sore."

I often check with the CDC's website for information about any communicable disease.
