The causes of reactivation are uncertain, but several potential triggers have been documented. A 2009 study showed the protein VP16 plays a key role in reactivation of the dormant virus.[71] Changes in the immune system during menstruation may play a role in HSV-1 reactivation.[72][73] Concurrent infections, such as viral upper respiratory tract infection or other febrile diseases, can cause outbreaks. Reactivation due to other infections is the likely source of the historic terms 'cold sore' and 'fever blister'.

Some people experience very mild genital herpes symptoms or no symptoms at all. Frequently, people infected with the virus don't even know they have it. However, when it causes symptoms, it can be described as extremely painful. This is especially true for the first outbreak, which is often the worst. Outbreaks are described as aches or pains in or around the genital area or burning, pain, or difficulty urinating. Some people experience discharge from the vagina or penis.

The frequency and severity of recurrent outbreaks vary greatly between people. Some individuals' outbreaks can be quite debilitating, with large, painful lesions persisting for several weeks, while others experience only minor itching or burning for a few days. Some evidence indicates genetics play a role in the frequency of cold sore outbreaks. An area of human chromosome 21 that includes six genes has been linked to frequent oral herpes outbreaks. An immunity to the virus is built over time. Most infected individuals experience fewer outbreaks and outbreak symptoms often become less severe. After several years, some people become perpetually asymptomatic and no longer experience outbreaks, though they may still be contagious to others. Immunocompromised individuals may experience longer, more frequent, and more severe episodes. Antiviral medication has been proven to shorten the frequency and duration of outbreaks.[79] Outbreaks may occur at the original site of the infection or in proximity to nerve endings that reach out from the infected ganglia. In the case of a genital infection, sores can appear at the original site of infection or near the base of the spine, the buttocks, or the back of the thighs. HSV-2-infected individuals are at higher risk for acquiring HIV when practicing unprotected sex with HIV-positive persons, in particular during an outbreak with active lesions.[80]


Although it’s not caused by either the HSV-1 or HSV-2 virus, herpes zoster falls under the umbrella of herpes diseases. Also known as shingles, it’s an infection caused by the varicella-zoster virus, and is characterized by the development of painful skin rashes on one side of the face or body.23 These rashes are red patches of fluid-filled blisters that tend to crack easily.24,25
Genital herpes is not usually accommodated by symptoms. Two-thirds of genital herpes cases are asymptomatic. Getting tested for both HSV-1 and HSV-2 is the only sure way to know if you have genital herpes. Blisters or sores in the genital area, fever, body aches, swollen lymph nodes, headaches, tiredness and painful urination call all be symptoms of genital herpes.
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]

Transmission of HSV-1 occurs by direct exposure to saliva or droplets formed in the breath of infected individuals. In addition, skin contact with the lesions on an infected individual can spread the disease to another individual. Although close personal contact is usually required for transmission of the virus, it is possible to transmit HSV-1 when people share toothbrushes, drinking glasses, or eating utensils.

Herpes symptoms commonly show in or around the mouth. Sores may also occur at the back of the throat, causing the lymph nodes in the neck to swell. Mouth herpes is very common in children, as their parents or relatives can pass it on to them easily by a greeting or goodnight kiss. To get a better understanding of oral herpes, let us take a look at its causes.


With the first outbreak of herpes virus infection, an individual may also experience nonspecific flu-like symptoms like fever, swollen lymph nodes, headache, and muscle aches. It is also possible to have herpes virus infection without having any symptoms or signs, or having signs and symptoms that are so mild that the infection is mistaken for another condition.
Herpes has been known for at least 2,000 years. Emperor Tiberius is said to have banned kissing in Rome for a time due to so many people having cold sores. In the 16th-century Romeo and Juliet, blisters "o'er ladies' lips" are mentioned. In the 18th century, it was so common among prostitutes that it was called "a vocational disease of women".[91] The term 'herpes simplex' appeared in Richard Boulton's A System of Rational and Practical Chirurgery in 1713, where the terms 'herpes miliaris' and 'herpes exedens' also appeared. Herpes was not found to be a virus until the 1940s.[91]
Genital herpes is contracted through sexual activity, and may show symptoms around the genital area (anus, buttocks, thigh, penis, vulva, etc.). Additionally, people with HIV can experience significantly worse symptoms of herpes.  See a doctor if your partner has herpes, or if you notice any unusual sores on your body.  How do you know if you have herpes?  Read more in our Diagnosing Herpes section here.  

Canker sores are sometimes thought to be caused by HSV, but this is not true. Canker sores occur only inside the mouth, on the tongue, and on the soft palate (roof of mouth), not on skin surfaces. Although they reoccur, they are not contagious, usually are self-limiting, and have almost no complications. Canker sores are caused by substances that irritate the lining of the mouth.


Homeopathic medicines can also be used to avoid any adverse effects of allopathic drugs and assist the body’s own healing mechanism. They are approved by FDA and are custom made by the medic in the right proportion to provide immediate relief. One such complete natural product is Herpeset which is to be sprayed on the affected areas especially the tongue. The natural components are quickly absorbed in the blood stream.
At the other end of the spectrum, there is a possibility of a herpetic flare up taking a sinister turn and leading to herpetic encephalitis. It is estimated to affect at least 1 in 500,000 individuals per year. The mechanism of this is not fully understood, but it is believed that the infection occurs through direct transmission of the virus via nerves from other parts of the body to the brain. In such cases, a person may complain of fever, headache, and lethargy, followed by confusion or delirium. In some cases, some people even develop seizures. This requires immediate medical attention and treatment.

When we say, “herpes” many of us are thinking about genital herpes, famously known as an incurable inconvenience. But there is more to it than being just a sexually transmitted infection. There are multiple ways that herpes can transmit but genital herpes is usually picked up from sexual contact. Apart from that, herpes can be transmitted when sharing an environment with someone who has the infection as well.
“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.
Your healthcare provider may diagnose genital herpes by simply looking at your symptoms. Providers can also take a sample from the sore(s) and test it. In certain situations, a blood test may be used to look for herpes antibodies. Have an honest and open talk with your health care provider and ask whether you should be tested for herpes or other STDs.

At least 80 to 90 percent of people in the U.S. have already been exposed to the HSV-1 virus.sup style="font-size: 10px;">21 Meanwhile, around 3.7 billion HSV-1 infections were recorded in 2012 all over the world, according to the World Health Organization. Africa was home to the highest number of cases, with 87 percent of occurrences coming from this continent.22

HSV infection causes several distinct medical disorders. Common infection of the skin or mucosa may affect the face and mouth (orofacial herpes), genitalia (genital herpes), or hands (herpetic whitlow). More serious disorders occur when the virus infects and damages the eye (herpes keratitis), or invades the central nervous system, damaging the brain (herpes encephalitis). People with immature or suppressed immune systems, such as newborns, transplant recipients, or people with AIDS, are prone to severe complications from HSV infections. HSV infection has also been associated with cognitive deficits of bipolar disorder,[13] and Alzheimer's disease, although this is often dependent on the genetics of the infected person.


Do everything possible to prevent spreading it to other people. The virus cannot live long when it is not in contact with the skin, so door handles and towels are not likely to spread it. Do not share your personal belongings, like toothbrushes and combs.  Wash your hands with soap and water often, and immediately if you touch the sores.  This is important so as to minimize the chance of getting ocular herpes (herpes infection of the eye) which is a serious infection. Be especially careful around infants because their immune systems may not be fully developed. Little children often express affection with sloppy wet kisses. This is a common way to spread the herpes virus within the family.
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.
Traditionally, it was assumed that HSV-1 strictly caused oral sores and blisters, whereas HSV-2 caused genital and/or rectal sores and blisters. However, the virus- or perhaps just our understanding of the virus itself- has evolved in such a way that doctors now recognize that either HSV-1 or HSV-2 can cause genital and/or rectal sores, albeit with HSV-2 causing the majority of sores in the genital or rectal areas.
Condoms offer moderate protection against HSV-2 in both men and women, with consistent condom users having a 30%-lower risk of HSV-2 acquisition compared with those who never use condoms.[49] A female condom can provide greater protection than the male condom, as it covers the labia.[50] The virus cannot pass through a synthetic condom, but a male condom's effectiveness is limited[51] because herpes ulcers may appear on areas not covered by it. Neither type of condom prevents contact with the scrotum, anus, buttocks, or upper thighs, areas that may come in contact with ulcers or genital secretions during sexual activity. Protection against herpes simplex depends on the site of the ulcer; therefore, if ulcers appear on areas not covered by condoms, abstaining from sexual activity until the ulcers are fully healed is one way to limit risk of transmission.[52] The risk is not eliminated, however, as viral shedding capable of transmitting infection may still occur while the infected partner is asymptomatic.[53] The use of condoms or dental dams also limits the transmission of herpes from the genitals of one partner to the mouth of the other (or vice versa) during oral sex. When one partner has a herpes simplex infection and the other does not, the use of antiviral medication, such as valaciclovir, in conjunction with a condom, further decreases the chances of transmission to the uninfected partner.[14] Topical microbicides that contain chemicals that directly inactivate the virus and block viral entry are being investigated.[14]
Recurrent outbreaks of genital herpes may happen, with some patients having four to six outbreaks in the span of a year. Compared to the first infection, subsequent recurrences are less painful and occur in shorter periods than the first infection. There are some patients, however, who don’t have another outbreak for many years or even once more during their lifetime.11

Herpes virus type 5 is also known as cytomegalovirus. It is the major cause of mononucleosis. Mononucleosis causes symptoms similar to infectious mononucleosis. It is spread via blood transfusion, breast-feeding, organ transplants, and sexual contact. The virus causes diarrhea, or severe vision problems and even leads to AIDS. People with weakened immune systems are more susceptible to these diseases.
If you have recently made it through a first episode that consisted of full-blown symptoms, you know something about signs and symptoms already. The good news is that the first episode is almost always the worst that HSV throws your way. Signs and symptoms of recurrent episodes (when they occur) tend to be milder and heal much more quickly, typically within two to twelve days.
'Using condoms or dams can help to protect against STIs, but herpes can also be passed on by skin-to-skin contact with the affected area, so it’s strongly recommended that you don’t have sex during this time,' she adds. 'This includes direct genital contact or skin-to-skin contact with the affected area, and doesn’t have to be penetrative sex,' says O’Sullivan.
