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. Herpes is most easily spread when a sore is present, but, it is also often spread at other times too. Some people notice itching, tingling or other sensations before they see anything on their skin.
