“You don’t want an infant delivered through infected birth canal or vulva because the infant can be infected,” Cullins explains. A neonatal herpes infection is a real risk because it can cause problems with brain development and eye and skin infections, or even be fatal. And since there is more risk for transmission from mother to baby during an initial outbreak than during a recurrent outbreak, the CDC stresses that it’s incredibly important for pregnant women to avoid contracting a new herpes infection.
The herpes simplex virus is probably the most well-known virus of the herpes family, and it is just as contagious. Herpes simplex infects epithelial cells and remains latent in neurons. HSV-1 causes recurrent oropharyngeal lesions, commonly known as “fever blisters" or "cold sores.” It is also the primary cause of sporadic encephalitis (inflammation of the brain), gingivostomatitis (inflammation of the gums and mucous lining of the mouth), and keratoconjunctivitis (severe dryness of the eye that involves the cornea) and dendritic corneal ulcers (also called HSV keratitis) in which the cornea becomes affected by herpetic lesions that look like the dendrites of neurons in the brain.
HSV-2 is commonly referred to as genital herpes because it usually causes cold sores to erupt around the genitalia. In fact, genital herpes is the No. 1 cause of genital ulcers worldwide, according to the Centers for Disease Control and Prevention (CDC), and affects up to 1 in 3 adults (although most who are infected don’t even know it). (5) Both types of herpes viruses are highly contagious, and both can cause cold sores in either area of the body (or sometimes both). 
Prescription antiviral medications are also commonly used to reduce the duration, severity, and incidence of outbreak. These medications include (but are not limited to) valacyclovir, acyclovir, and famciclovir. Remember that these medications will not cure HSV-1 or HSV-2. Instead, they will help reduce the amount of time the outbreak is present, and help control the severity of symptoms.
Herpes is contracted through direct contact with an active lesion or body fluid of an infected person.[31] Herpes transmission occurs between discordant partners; a person with a history of infection (HSV seropositive) can pass the virus to an HSV seronegative person. Herpes simplex virus 2 is typically contracted through direct skin-to-skin contact with an infected individual, but can also be contracted by exposure to infected saliva, semen, vaginal fluid, or the fluid from herpetic blisters.[32] To infect a new individual, HSV travels through tiny breaks in the skin or mucous membranes in the mouth or genital areas. Even microscopic abrasions on mucous membranes are sufficient to allow viral entry.

A scary finding is that more cases of genital herpes than ever before are now being caused by HSV-1 (the type most people assume only causes mouth sores), and about 85 percent of people with genital herpes don’t even know it. (7) Studies show that about 50 percent of the new genital herpes infections in young adults are due to HSV-1 and about 40 percent in older adults. The fact that most people don’t ever find out they’re infected is one of the reasons that transmission rates are steadily climbing.

However, there is much more to the herpes virus than just chicken pox or genital herpes. For instance, after an active infection, the virus is shed (eliminated) in the urine and feces for up to several months (sometimes years in the case of the cytomegalovirus) after the active infection has resolved. This means the infected person is still contagious, which is what makes this virus so contagious. It can easily be transferred when the patient is asymptomatic.

Following active infection, herpes viruses establish a latent infection in sensory and autonomic ganglia of the nervous system. The double-stranded DNA of the virus is incorporated into the cell physiology by infection of the nucleus of a nerve's cell body. HSV latency is static; no virus is produced; and is controlled by a number of viral genes, including latency-associated transcript.[70]
Herpes simplex viruses -- more commonly known as herpes -- are categorized into two types: herpes type 1 (HSV-1, or oral herpes) and herpes type 2 (HSV-2, or genital herpes). Most commonly, herpes type 1 causes sores around the mouth and lips (sometimes called fever blisters or cold sores). HSV-1 can cause genital herpes, but most cases of genital herpes are caused by herpes type 2. In HSV-2, the infected person may have sores around the genitals or rectum. Although HSV-2 sores may occur in other locations, these sores usually are found below the waist.
Genital herpes is an incurable disease. But, there are medications to relieve symptoms and prevent recurrent outbreaks. Prosurx is the best and most common treatment option for genital herpes. It can give your partner immediate relief and stop their outbreak before it starts. Prosurx can also reduce your partner’s risks of spreading the virus to you. So, ask your partner to apply Prosurx 2-3 times a day to get rid of genital herpes.
Herpes is transmitted via skin-to-skin contact, not through blood or saliva. Cullins explains that someone with HSV can be shedding the herpes virus without having an outbreak (known as asymptomatic virus shedding), and infect somebody that way. Suppressive antiviral medications, like acyclovir or valacyclovir, inhibit HSV replication, which decreases shedding but does not completely eliminate it, says Johnston.
Herpes sores usually appear as one or more blisters on or around the genitals, rectum or mouth. The blisters break and leave painful sores that may take a week or more to heal. These symptoms are sometimes called “having an outbreak.” The first time someone has an outbreak they may also have flu-like symptoms such as fever, body aches, or swollen glands.
Consequently, you may already have the virus. A doctor can determine this with a blood test for Herpes 2 (Ig), a type-specific immunoglobulin. If you are already infected, you won’t be at risk for a new infection — you and your boyfriend already share the virus. But knowing your herpes status will tell you whether you are capable of infecting a future partner.
Laboratory testing is often used to confirm a diagnosis of genital herpes. Laboratory tests include culture of the virus, direct fluorescent antibody (DFA) studies to detect virus, skin biopsy, and polymerase chain reaction to test for presence of viral DNA. Although these procedures produce highly sensitive and specific diagnoses, their high costs and time constraints discourage their regular use in clinical practice.[39]
However, asymptomatic carriers of the HSV-2 virus are still contagious. In many infections, the first symptom people will have of their own infections is the horizontal transmission to a sexual partner or the vertical transmission of neonatal herpes to a newborn at term. Since most asymptomatic individuals are unaware of their infection, they are considered at high risk for spreading HSV.[47]

What is herpes gladiatorum? Herpes gladiatorum is a virus similar to that which causes the common cold. It is spread through skin-to-skin contact. The symptoms vary between people, but they include a fever and skin sores. If the virus affects the eyes, it can be dangerous. Find out about the symptoms, risks, treatment, and prevention options.

Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
Primary Infection: This is the first stage wherein the contagion reproduces upon entering from the mucous membrane or skin. Typical symptom is the appearance of oral lesions which may not be present initially resulting in an asymptotic infection. In this case due to lack of symptoms one will be unaware of the presence of an infection. The sores usually takes 21 days to form and become visible, then the blisters will persist up to 10 days before beginning to heal.

Human herpes virus 2 (HHV2) is also called herpes simplex virus 2 (HSV2). It typically causes genital herpes, a sexually transmitted infection. However, it can also cause cold sores in the facial area. Like HHV1, the HHV2 infection is contagious and is spread by skin-to-skin contact. The main route of transmission is through sexual contact, as the virus does not survive very long outside the body.
“Someone having HSV doesn't mean that they were reckless or irresponsible with their sex life,” says Sara, age 30. “I used condoms with all my partners, and I still caught it.” For Jamie, who contracted herpes from her husband three years into their monogamous relationship, he was her first and only sexual partner. And she says that he contracted it from one of his very first sexual encounters. No matter how and why someone contracted the virus, it doesn't erase their humanity and right to respect.

OK, so the majority of people have it. Just this year, the World Health Organization released a study that estimates two thirds of people in the world (67%) have the HSV-1 strain of the herpes simplex virus — that’s approximately 3.7 billion people worldwide. While HSV-1 typically refers to oral herpes infections, it also includes some genital infections. The new report estimates that half of the HSV-1 infections in people between the ages of 15–49 are actually genital infections transmitted via oral-to-genital contact. The Center For Disease Control (CDC) estimates that 1 in 6 people have genital herpes.

In this article, we will discuss what you need to know about the herpes virus. Herpes has been around for thousands of years. During most of this time, it has not been very well understood. It was not known to be caused by a virus until the 19405. Not until late in the 1960s were two separate viruses isolated. Physicians confidently misdiagnosed the disease until only recently. More has been written and learned about herpes in the last two years than in the last two thousand years put together.
"Oral herpes is an infection found in the mouth, or on and around the lips, caused by the Herpes Simplex Virus (HSV)," Michael explains. "There are two types or strains of this virus called HSV1 and HSV2. Usually, the HSV1 strain infects the mouth and lips, and the HSV2 strain infects the genitals. It is however possible for HSV2 to infect your mouth and lips."
