Herpes simplex virus 1 and 2 (HSV-1 and HSV-2) are two strains of the Herpes virus family, Herpesviridae, which cause infections in humans. After an initial, or primary, infection, HSV establishes latency, during which the virus is present in the cell bodies of nerves which innervate the area of original outbreak. Herpes infections are marked by painful, watery blisters in the skin or mucous membranes (such as the mouth or lips) or on the genitals.
HSV is generally transmitted by direct contact of lips or genitals when the sores are present, or just before they appear (known as shedding).
Entry and replication of the HSV involves interactions of several viral glycoproteins with cell surface receptors or particles. Once bound to the HVEM, glycoprotein D changes its conformation and interacts with glycoproteins H and L, which form a complex. The packaging of the viral particles, which include the genome, core and the capsid, occur in the nucleus.

Oral herpes is easy to diagnose when a patient has visible sores or ulcers, but early stages of herpes on the face and mouth as well as on the genitals are harder to diagnose. Herpes should be distinguished from herpes zoster, chicken pox, impetigo, and drug eruptions. Herpetic sores are classified as heat sores in TCM because the lesions are red and follow febrile disease conditions. As with all treatment protocols, be sure to tailor and modify the basic treatments below to fit your patient's specific constitution, root cause, and symptoms. Treatment principle: Drain Spleen and Stomach damp heat, nourish yin, drain deficient heat . Cash, checks and credit cards are also gratefully accepted if you prefer to donate in person.

Beltina.org The Eyes Ocular Herpes SimplexOcular Herpes SimplexOcular Herpes Simplex - an INFECTION of the eyes with HERPES SIMPLEX VIRUS 1 (HSV-1), which causes cold sores, or herpes simplex virus 2 (HSV-2), which causes GENITAL HERPES. About half of people who have one outbreak of ocular herpes simplex will experience a second; about 20 percent have persistently recurring infections, ranking ocular herpes simplex as the leading infectious cause of corneal destruction.
During reactivation, virus is produced in the cell and transported outwardly via the nerve cell’s axon to the skin.


The blisters resemble those seen in Chickenpox — an infection caused by a third member of the alpha-Herpesviridae subfamily, Varicella Zoster Virus (VZV), also known as Human Herpes Virus 3 (HHV-3).
In addition, herpes may be transmitted during childbirth, which can be fatal to the infant. The virus particle contains an envelope which, when bound to specific receptors on the cell surface, will fuse with the cell membrane.
Glycoprotein B interaction with the glycoprotein H and L complex allows the virus to enter into the cell.
In the nucleus, cleavage of genome concatemers occurs and these are placed into pre-formed capsids. During active disease phases there are blisters on the skin which contain the infectious virus. The virus spreads to the eye to cause the initial infection via contamination from contact with an existing herpes sore elsewhere on the body. A serious complication of ocular herpes simplex is stromal KERATITIS, in which the IMMUNE SYSTEM begins to attack the stromal cells that make up the cornea. The antiviral medication acyclovir may reduce the severity of outbreaks of the infection when taken at the first sign of symptoms.
The ability of Herpes virus to establish latency leads to the chronic nature of Herpes infection; after the initial infection subsides, Herpes symptoms may periodically recur in the form of outbreaks of herpetic sores near the site of original infection. The immature immune system of the child is unable to defend against the virus and even if treated, infection can result in brain damage.
The viral particle migrates to the nucleus, where the genome is replicated using enzymes from the host cell. The viral envelope is acquired from the nuclear envelope, more specifically the inner lamellae of the membrane. He simply pursues his vision of excellence at whatever he does, leaving others to decide whether he is working or playing. Accompanying symptoms may include high fever and swelling of tenderness of the lymph nodes. Ocular herpes simplex features similar eruptions of sores on the surface of the EYE and inside the eyelids. This leads to scarring deep within the cornea, resulting in distortions of vision and diminished VISUAL ACUITY. Some studies show that taking acyclovir for 12 months significantly reduces recurrent ocular herpes simplex.


Transmission occurs while passing through the birth canal and the risk of infection is minimal if there are no symptoms or exposed blisters during delivery. Initially, glycoprotein C, on the surface of the viral envelope, targets and binds to a cell surface particle, heparan sulfate. Upon entering the cell, an ?-TIF protein also joins the viral particle and aids in immediate early Transcription. Crusting of the lesions begins after three to four days of onset and complete healing within three weeks. This is particularly likely during an outbreak, although individuals may shed virus between outbreaks. The first outbreak after exposure to HSV is commonly more severe than future outbreaks, as the body has not had a chance to produce antibodies; this first outbreak also carries the risk of developing meningitis. Viruses are transported along the sensory nerves to the nerve cell bodies where they go dormant and reside as long as the host is alive. Although no cure is yet available, treatments exist which reduce the likelihood of viral shedding. Two major glycoproteins, glycoprotein B and glycoprotein D, also associate with the cell membrane.
This enzyme shuts off protein synthesis in the host, degrades host mRNA, helps in viral replication, and regulates gene expression of viral proteins. They may come out of dormancy because of a variety of triggers (one of which is immunosuppressant drugs).
Infectioncontrol methods, such as frequent HAND WASHING and keeping the fingers away from the eyes, can help prevent initial infection.
Glycoprotein D binds specifically to the herpesvirus entry mediator receptor (HVEM), thus providing a strong, fixed attachment to the host cell. While the viral genome immediately travels to the nucleus, the VHF protein remains in the cytoplasm. When it becomes active the virus multiplies, travels along the axon of the neuron to the nerve terminals in the skin and releases the virus particles.
