Having been infected with HSV1, the immune system has already manufactured, and kept on reserve, antibodies to this virus. Another source of confusion about herpes transmission is autoinnoculation. The herpes simplex virus is a contagious virus that can be passed from person to person through direct contact. Infection with HSV-1 can happen from general interactions such as eating from the same utensils, sharing lip balm, or kissing. Genital herpes isn’t typically caused by HSV-1; it’s caused by another type of the herpes simplex virus called herpes simplex virus-2 (HSV-2) and is spread by sexual contact. But even though HSV-1 typically causes sores around the mouth and HSV-2 causes genital sores, these viruses can cause sores in either place.
Most cases of genital herpes are caused by HSV-2. Genital herpes is a sexually transmitted disease. While genital HSV can be a frustrating and painful condition, in general the virus is less a medical problem than a social problem. Simply touching an infected person is often the way children get exposed. Transmission of HSV-1 occurs by direct exposure to saliva or droplets formed in the breath of infected individuals. Oral herpes (cold sores) is an infection caused by the herpes simplex virus (HSV). Oral herpes (HSV-1) infection (or exposure without noticeable infection) is common.
Transmission of Herpes Viruses: HSV1 and HSV2 Herpes (types 1 and 2) can be transmitted through skin to skin contact, kissing, sexual intercourse, and oral sex. There is, however, a significant percentage of genital herpes infections resulting from oral to genital sexual contact.
