It usually causes diseases such as kertaoconjuctivitis, gingivostomatitis, encephalitis and recurrent herpes labialis. A Herpes Simplex Virus enters the body not through simple skin contact but through mucous membranes.
In some rare cases herpes simplex infection also spreads to other body parts such as eyes and brain. Once the virus enters your body it never leaves, but shows its signs of outbursts occasionally.
Most of the infections caused by type 1 virus occur in the childhood and this is evident due to the presence of antibodies to the virus. The herpes simplex virus replicate in the mucous membrane or the skin at the primary site of the infection. To detect Herpes Simplex Virus, tests are conducted by examining the sores on the body parts. Other rapid diagnostic tests include enzyme linked immunosorbent assays (ELISA) in which virus-specific glycoproteins are detected. Certain serological tests for instant the neutralization test can be employed in making the diagnosis of herpes infection. In those women with genital herpes or positive cultures for virus, cesarean section is suggested. Herpes is a very common infection caused by a virus, called the herpes simplex virus, or HSV. The course and symptoms of herpes infections vary widely from being completely asymptomatic throughout a person's life in 80% of patients, to having frequent recurrences.
HSV-1 is typically spread via infected saliva and initially causes acute herpetic gingivostomatitis in children and acute herpetic pharyngotonsillitis in adults. Acute herpetic pharyngotonsillitis is the most common first presentation of the disease in adults, and more commonly affects the pharynx and tonsils than the mouth and lips.
Although genital herpes is usually caused by HSV-2, it can also be caused by HSV-1 (for instance by contact of a mouth lesion on genital skin of a non-infected person). The good news is that a person who already has antibodies to HSV-1 because of a prior infection with oral herpes causes a milder effect of genital HSV-2 and protects against acquiring HSV-1 in the genital area. It's a good idea to go in to see your doctor if you are worried that you may have contracted herpes.
In general, there are some mixed confusion about common cold sores around the mouth and whether are all cold sores caused by herpes virus. However, there are many individuals who got the standard cold sores mixed up with canker sores (which is also sometimes refer to as cold sores by laymen) or even with shingles (also another form of herpes infection with similar symptoms that may occur around the mouth).
Oral herpes is also commonly known as cold sores (or fever blisters) due to the fact that the infection or outbreaks usually occur when the immune system of an individual is weaken or when someone is having an illness (like during a fever or common cold). Also refered as herpes zoster, shingles is a reactivation of the varicella-zoster virus (VZV) that causes chicken pox.


Shingles is most commonly mixed up with the herpes simplex virus (HSV) since symptoms of an outbreak can be quite similar and painful. In the past, cold sores have generally been herpes simplex virus type 1 (HSV-1), however, due to increase incidences of oral-genital contact during sexual activity between partners, people can get HSV-1 on their genitals and cause genital herpes. On the other hand, individuals can also contract herpes simplex type 2 (HSV-2) on their mouth if oral sex is performed on a partner with HSV-2 genital herpes infection. Note: If a person gets genital herpes from a partner who has HSV-1 during oral-genital sex, the genital herpes infection will be a type 1 herpes virus and will not become a type 2 genital herpes infection. Generally speaking, there are many people out there who do not considered cold sores as a form of STD if the herpes simplex virus is type-1 since so many people are exposed to it and many associate the stigma of STD as a form of disease that are transmitted through vaginal or anal sex. However, since the medical discovery that it is possible to transmitted HSV-2 to the mouth during oral-genital sex, cold sores (oral herpes) is now considered an STD.
In general, if the cold sores are visible, the health care professional will perform a viral swab test called viral culture to get a sample of the sore to be tested in a lab.
For initial outbreaks of oral herpes, the symptoms are usually quite severe and painful and doctors may prescribe oral antiviral medications such acyclovir (zovirax), famciclovir (famvir) or valacyclovir (Valtrex) to help reduce the pain and speed up the healing of the sores. In contrast, antibodies to type 2 virus does not appear until the age of sexual activity is achieved. In this test the cells or fluids from blisters or blood or the spinal fluid is taken to find the genetic material of the HSV virus. These include acyclovir which is first line of drug for treating systemic diseases and encephalitis caused by HSV1. Once a person acquires the herpes virus, it invades and replicates in the nervous system, remaining deep within a nerve for life. Along with ruptured vesicles in the tonsils and pharynx, an adult with newly acquired herpes type 1 can have fever, headache, fatigue, and sore throat. There are many over-the-counter medications and home remedies that claim to help or cure herpes, but most of these are false claims and do very little, if anything at all, to help.
So, it may not be surprising to know that people who had the herpes simplex cold sores been told that they have canker sores or shingles, and vice versa. Most commonly, herpes simplex virus type 1 (HSV1) causes the primary and recurrent outbreaks of small painful blisters, especially on the lips and around the mouth which is refer to as oral herpes. The association of cold sores as cranker sores or vice versa often comes from laymen who do not know how to differentiate between the two condition and which is what causes the confusion and mixed up. Even when the chicken pox rash is gone, the varicella-zoster virus continues to remain latent in the nerves of the body until is is reactivated again as shingles that causes painful blisters on the skin that typically affects one side of the body. However, the key difference is shingles rarely recurs and if it does get reactivated, it will only occur in 3% of adults aged 60 or older due to a weak immune response to the varicella-zoster virus. However shingles is not related to as any form of sexually transmitted diseases such as the herpes simplex virus that causes herpes genitalis, or oral herpes.
The same goes to say that herpes simplex type 2 cold sores can cause a HSV-2 genital herpes infection.


If there are no visible physical sores or if the sores have healed, clinicians may opt for a blood antibody test called the Western blot herpes antibody test to look for antibodies to the herpes virus in the blood.
It can easily be prevented by recommending caesarean section to the woman with herpes virus. People getting infected by it by their partners may not see the symptoms in their partners as virus may be in its dormant stage, but it successfully makes a human its carrier. The two virus types are very closely related, but differ in how each is spread and the location of the infection. The virus can remain latent (no symptoms) for years, but can also become reactivated during periods of illness, emotional stress, trauma, or other triggers, such as sunlight and menstruation.
As in oral herpes, each outbreak starts with a feeling of pain or burning at the site, followed by a localized patch of vesicles that can be very painful.
Medically speaking, all cold sores are herpes however canker sores are not herpes related and they are definitely not contagious.
The type 1 causes infection above the waist while the type 2 virus causes infection below the waist.
HSV1 causes cold sores on the lips, generally spread by kissing or sharing and eating in same utensils during the infection. This allows the virus to replicate and not only cause recurrent disease but also to shed viral particles which can be spread to other people. Particles of the virus shed from the lesion, making it contagious to others who have never had it before, with maximal shedding occurring in the first 24 hours but lasting up to 5 days. As in oral herpes, genital herpes also causes vesicles to form, which can appear on vagina, labia, buttocks, or even the cervix in women, and on the penis, scrotum, buttocks, thighs, and even urethra in men. Barrier protection such as with a condom can help prevent spread of genital herpes, but some HSV ulcers can occur outside o the area protected by the condom and still be transmitted. Docosanol and penciclovir are good drugs for treating recurrent oropharyngeal herpes as a result of type 1 infection especially in immunodeficient patients. HSV-1 more commonly affects the area around the mouth, while HSV-2 is more likely to affected the genital area, but both viruses can affect either region. For most healthy people, herpes infections are a painful nuisance of recurrent blisters in a localized area. However, in people with poor immune systems, such as organ transplant recipients or people with HIV, the virus can spread throughout the body and cause severe disease, even of the brain. Although there are antiviral medications to help reduce the viral burden, it does not cure the infection.
