Herpes Simplex Virus is a virus which causes the infection known as Herpes Simplex.  Herpes Simplex Virus belongs to a family of virus called Herpesviridae. It usually causes diseases such as kertaoconjuctivitis, gingivostomatitis, encephalitis and recurrent herpes labialis. It is a disease in which painful vesicular lesions are produced in the anal and genitals of both male and female. It arises due to contact with vesicular rashes within the birth canal.  This virus is shed and can infect the baby during delivery. Neonatal herpes can occur by both type of viruses and both can cause serious sort of infection in neonates.  But no congenital abnormalities of significant nature are found to occur with either of the infections.
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.
When the infection spreads besides the usual spots to other body parts like brain, the Polymerase chain reaction (PCR) test is conducted. 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.
Each particle (virion) consists of a deoxyribonucleic acid (DNA) genome surrounded by an icosahedral capsid, which is itself surrounded by an envelope covered in glycoprotein spike.

Symptoms include fever, vesicular lesions in the mouth and irritability.  The initial disease is more severe and it remains for a considerable period of time. In contrast, antibodies to type 2 virus does not appear until the age of sexual activity is achieved.


It then moves up the neuron and there becomes latent in the ganglion particularly sensory ganglion cells. 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. It is a good test as it detects the rise in antibody titer accurately.  But this test is only helpful in primary infection whereas it holds no importance in recurrent infections. These include acyclovir which is first line of drug for treating systemic diseases and encephalitis caused by HSV1.
Members of the herpes virus family include several that infect humans: herpes simplex viruses type 1 and type 2 (oral and genital herpes), varicella-zoster virus (chicken pox and shingles), Epstein-Barr virus (glandular fever) and cytomegalovirus (various infections). The encephalitis of HSV1 is characterized by a formation of necrotic lesion particularly in the temporal area of the brain.
It can easily be prevented by recommending caesarean section to the woman with herpes virus. Cold sores over the mouth are caused by the HSV1 and the second virus type HSV2 is more responsible for herpes genital.
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. HSV1 becomes dormant in the trigeminal ganglia while HSV2 in the sacral and lumbar ganglia. The herpes viral culture test may also be conducted wherein fluids or cells from the blisters are collected onto a cotton swab and put into a culture cup; it is then tested for the herpes infection and gives specific results especially for detecting herpes genital. It is done by taking cells from the skin lesions and staining with the Giemsa stain.  If multinucleated giant cells are found, then it confirms the infection by herpes. 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. Docosanol and penciclovir are good drugs for treating recurrent oropharyngeal herpes as a result of type 1 infection especially in immunodeficient patients.
