An infection of herpes simplex virus type 2 (HSV2) can lead to genital herpes, a sexually transmitted disease that causes blisters and pain in the genital area. Both types of the virus can be transmitted through direct contact. A person can get the cold sores of HSV1 by kissing or sharing eating utensils with an infected person. A person can get genital herpes or HSV2 by having intimate contact with an infected person. A mother who has genital herpes can pass the infection on to her newborn if she delivers the baby vaginally.
