Neonatal herpes simplex is a HSV infection in an infant. It is a rare but serious condition, usually caused by vertical transmission of HSV-1 or -2) from mother to newborn. During immunodeficiency, herpes simplex can cause unusual lesions in the skin. One of the most striking is the appearance of clean linear erosions in skin creases, with the appearance of a knife cut. Herpetic sycosis is a recurrent or initial herpes simplex infection affecting primarily the hair follicles.:369 Eczema herpeticum is an infection with herpesvirus in patients with chronic atopic dermatitis may result in spread of herpes simples throughout the eczematous areas.:373
After exposure to the virus, many people experience a so called primary infection which is typically associated with sores on or around the genitals or the anus. During a primary infection some people experience pain in the groins or a mild fever. Not all infected individuals experience a primary infection or show any symptoms at all, but they can still pass the disease on to other people.
There’s herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2). “HSV-1 and HSV-2 are different but closely related viruses,” says Dr. Christine Johnston, MPH, who is the Associate Medical Director of the Virology Research Clinic at the University of Washington. Johnston explains that both are transmitted through close mucosal or skin contact with infected secretions. HSV-1 primarily causes oral outbreaks, also known as cold sores, and HSV-2 usually causes genital outbreaks. But HSV-1 can also cause genital outbreaks through oral-to-genital contact, according to the CDC. According to Johnston, genital HSV-1 is less likely to recur than HSV-2, and there’s less asymptomatic shedding (transmitting the virus without realizing it) with HSV-1 than with HSV-2.
Herpes infection of the genital tract is a sexually transmitted infection (sexually transmitted disease or STD). Like in the mouth area, herpes symptoms and signs include a painful, blistering rash around or on the genital or rectal areas. These lesions open and result in painful sores that can take two to four weeks to heal. The sores can sometimes cause painful urination. Recurrent outbreaks are typical, and the time between outbreaks varies among affected people and even within the same individual. Prior to an outbreak, a tingling, burning, or itching sensation may be present on the area of involved skin.
So, if you have unprotected sex with your partner, you could be infected, too. Any form of sexual contact (oral, vaginal and anal sex) can put you at risks” the doctor said. Even when you use condoms or dental dams during sex, you can possibly contract HSV. In fact, condoms cannot provide 100 percent protection against genital herpes. Directly touching your partner’s genitals can also make you become infected. This happens when your partner develops visible herpes sores on their genitals.
A 2004 study in the New England Journal of Medicine found that suppressive therapy decreases the risk of HSV-2 transmission from symptomatic, infected partners to uninfected partners by 48%. So “the risk of transmission is significantly reduced, but cannot be eliminated even with suppressive therapy,” Johnston explains, and she stresses that the virus can be passed along even without signs or symptoms.
