Genital herpes is generally localised to the genitals, it can also spread to the mouth area (cold sore). These are the two areas where a person can get it.
It cannot be spread by swimming or drinking from the same cup since it is easily destroyed once exposed.
"Herpes is spread by direct skin to skin contact. Unlike a flu virus that you can get through the air, herpes spreads by direct contact, that is, directly from the site of infection to the site of contact. For example, if you have a cold sore and kiss someone, you can transfer the virus to their mouth. Similarly, if you have active genital herpes and have vaginal or anal intercourse, you can give your partner genital herpes. Finally, if you have a cold sore and put your mouth on your partners genitals (oral sex), you can give your partner genital herpes."
