Herpesviridae is a family of viruses which cause diseases in humans and animals such as the macaque monkey and the mouse. This editable Main Article is under development and not meant to be cited; by editing it you can help to improve it towards a future approved, citable version. The herpes simplex virus is one of the herpes, DNA viruses that are important in causing human disease.
It is "composed of an inner core containing linear double-stranded DNA, surrounded concentrically by an icosahedral capsid of approximately 100 nm, an amorphous layer termed the tegument, and an outer envelope composed of lipids and glycoproteins." (Paula W. Using the Baltimore classification (which is based on the mechanism of mRNA production) is a Group 1 virus (dsDNA) from the family Herpesviridae, subfamily Alphaherpesvirinae, Genus Simplexvirus and Species Herpes simplex virus 1. Herpes can be found throughout human history by reading texts from the past that describe the characteristics of the fever blisters. In addition to affecting the oral and genital areas of the body, HSV can infect other areas. In this research experiment, Becket Feierbach and his associates looked to determine how HSV-1 develops spatial compartments within the host's nucleus where replication takes place. The third research article I found dealt with a possible vaccine that is being developed to prevent being infected with HSV-2.

They believe the herpes simplex virus is a significant factor in developing the debilitating disease and could be treated by antiviral agents such as acyclovir, which is already used to treat cold sores and other diseases caused by the herpes virus.
Alzheimer's disease (AD) is characterised by progressive memory loss and severe cognitive impairment. Professor Ruth Itzhaki and her team at the University's Faculty of Life Sciences have investigated the role of herpes simplex virus type 1 (HSV1) in AD, publishing their very recent, highly significant findings in the Journal of Pathology.
Most people are infected with this virus, which then remains life-long in the peripheral nervous system, and in 20-40% of those infected it causes cold sores.
The team discovered that the HSV1 DNA is located very specifically in amyloid plaques: 90% of plaques in Alzheimer's disease sufferers' brains contain HSV1 DNA, and most of the viral DNA is located within amyloid plaques. The team had discovered much earlier that the virus is present in brains of many elderly people and that in those people with a specific genetic factor, there is a high risk of developing Alzheimer's disease. The team's data strongly suggest that HSV1 has a major role in Alzheimer's disease and point to the usage of antiviral agents for treating the disease, and in fact in preliminary experiments they have shown that acyclovir reduces the amyloid deposition and reduces also certain other feature of the disease which they have found are caused by HSV1 infection.
Professor Itzhaki explains: "We suggest that HSV1 enters the brain in the elderly as their immune systems decline and then establishes a dormant infection from which it is repeatedly activated by events such as stress, immunosuppression, and various infections.
The team now hopes to obtain funding in order to take their work further, enabling them to investigate in detail the effect of antiviral agents on the Alzheimer's disease-associated changes that occur during HSV1 infection, as well as the nature of the processes and the role of the genetic factor. Virus can spread through direct contact with fluid from the rash blisters caused by shingles. The Shingles is less contagious than the chickenpox and the risk of a person with shingles spreading the virus is low if the rash is covered. Shingles is contagious and can be spread from an affected children, person to babies or adults who have not been chickenpox or have not had the chickenpox vaccine. Close, personal contact with open blisters passes the shingles virus from one person to another. Keeping the shingles rash clean and covered can help prevent spreading the virus to others who are at risk. To date, the pathogenesis of VZV infection is not fully understood because VZW is an exclusively human pathogen and is difficult to replicate in animal models (Breuer & Whitley, 2007).
Among immunocompromised populations, herpes zoster rashes typically are more severe and prolonged and may become disseminated, indicating VZV viremia. VZV rashes typically are presented by a well-defined dermatomal distribution in immunocompetent individuals, so the diagnosis can be established by characteristic clinical presentation.

Acyclovir, famciclovir, and valacyclovir are nucleoside analogs that inhibit replication of human herpesviruses and are approved by the U.S. Since VZV prophylaxis has been shown to effectively decrease the incidence of VZV reactivation and reduce disseminated VZV infection in BMT recipients, VZV prophylaxis should be considered for hematologic patients without BMT with severe myelosuppression. Among high-risk patients without transplantation, reactivation and disseminated VZV infection also can occur. They can cause recurrent infections due to their invasive action on the immune system.Herpes viruses are composed of two double-stranded, linear DNA genomes which encode from 100 to 200 genes.
7, 2008) a€” The virus behind cold sores is a major cause of the insoluble protein plaques found in the brains of Alzheimer's disease sufferers, University of Manchester researchers have revealed. Another future possibility is vaccination against the virus to prevent the development of the disease in the first place. It affects over 20 million people world-wide, and the numbers will rise with increasing longevity.
The team had previously shown that HSV1 infection of nerve-type cells induces deposition of the main component, beta amyloid, of amyloid plaques.
They very much hope also that clinical trials will be set up to test the effect of antiviral agents on Alzheimer's disease patients. In such case someone with shingles can pass the varicella-zoster virus to you, because you don’t have it in your body. But the virus that causes shingles like the varicella zoster virus can be spread from a person with active shingles to another person who has never had chickenpox. While the blisters are fresh or oozing you’re considered contagious to people who haven’t had chickenpox or who have a compromised immune system.
Vaccine reduces the risk of getting shingles and having the widespread nerve pain associated with it.
However, the clinical presentation may be atypical or may have disseminated disease without rashes in immunocompromised patients; as a result, laboratory tests, including polymerase chain reaction, direct fluorescent antibody, and viral culture are needed to confirm the diagnosis.
Monitoring CD4 counts may be useful for clinicians in determining the need for VZV prophylaxis among high-risk populations, such as (a) hematologic patients with cancer following cytotoxic chemotherapy who fail to recover from myelosuppression over a prolonged period of time, (b) patients with myelodysplastic syndrome who have severe leukopenia refractory to granulocyte-colony-stimulating factor or granulocyte- macrophage-colony-stimulating factor, and (c) patients anticipating a prolonged course of immunosuppressive therapy who also are VZV seropositive (indicting a latent VZV state). Two patients with solid cancers in the first author's practice developed disseminated VZV infections -- one patient with breast cancer receiving standard adjuvant chemotherapy and one patient with metastatic colorectal cancer who received chemotherapy over four years.
They are nuclear replicating, transcribing the viral DNA to RNA in the nucleus of the infected cell. Together, these findings strongly implicate HSV1 as a major factor in the formation of amyloid deposits and plaques, abnormalities thought by many in the field to be major contributors to Alzheimer's disease.
In some cases, the person exposed to the virus might develop chickenpox but will not develop.
Once they have chickenpox, a person cannot be catch virus (or contract the virus) from someone else. Primary infection with VZV results in varicella or chickenpox, which largely affects children with a mild, self-limiting course (Wharton, 1996). Women have a slightly higher risk than men, and African Americans have a lower incidence of herpes zoster (Opstelten, Van Essen, Schellevis, Verheij, & Moons, 2006).
During initial viraemia, infected CD4 T cells cause down regulation of the histocompatibility complex class I expression and allow VZV to escape from the immune system (Ku, Padilla, Grose, Butcher, & Arvin, 2002). The most common rash sites are the thoracic and lumbar dermatomal zones (Yawn et al., 2007).
Therefore, considering VZV prophylaxis is clinically reasonable to reduce the risk of deadly disseminated VZV infection among high-risk patients with cancer without BMT. After clinical resolution of primary infection, viral latent infection is established when VZV retrogrades into the sensory dorsal roots of ganglia (Breuer & Whitley, 2007). In addition, infected T cells transport VZV via T-cell trafficking from tonsillar tissue to the skin, where VZV replicates and produces cell-free VZV, resulting in highly infectious skin lesions.

The rashes initially are erythematous and maculopapular, then progress to coalescing clusters of clear vesicles that contain high concentrations of VZV, which are contagious for VZV seronegative individuals. However, direct fluorescent antibody offers rapid diagnosis and is highly sensitive (Chan, Brandt, & Horsman, 2001). Therapy should be initiated within 72 hours of rash onset or as soon as possible (Dworkin et al.) (see Table 1). A retrospective analysis of 192 allogeneic peripheral blood stem cell transplantation recipients indicated that a very low dose of acylovir (200 mg daily) protected against VZV reactivation (Kim et al., 2008).
In addition, the prophylaxis regimen may decrease patients' physical suffering and associated hospitalizations. Food and Drug AdministrationDefinitionShingles, or herpes zoster, is a disease caused by the varicella zoster virus. Vaccination in children to prevent primary VZV has reduced chickenpox cases in the United States (Marin, Guris, Chaves, Schmid, & Seward, 2007).
Uninfected T cells also arrive at the infection sites, become primed with cell-free VZV, and mount a systemic immune response to control the initial infection (Ku et al., 2005). In immunocompetent people, the rashes crust in 7-10 days and are no longer infectious (Harpaz et al., 2008). The specimen is obtained by scraping the bases of uncrusted vesicular skin lesions and placing the scrapings on a plain glass slide. Similarly, 137 BMT recipients who were given long-term acylovir of 200 mg daily until the end of immune suppression and at least one year following BMT had significantly decreased incidence of VZV reactivation, and visceral dissemination and serious complications were completely eliminated (Asano-Mori et al., 2008). After the chicken pox symptoms fade away, the virus may reappear after a prolonged period of time in the form of shingles.Herpes is a disease caused by the herpes simplex virus type 1 and 2.
Herpes zoster, the second clinical condition of VZV infection, results from the reactivation of this latent neurotropic virus and commonly presents with painful, unilateral vesicular skin eruption distributing within the dermatomal zones (Gnann & Whitley, 2002). Following initial infection, the VZV-specific cell-mediated immunity keeps VZV in latency and prevents its reactivation (Breuer & Whitley). Although VZV cutaneous dissemination may start with a dermatomal rash, it presents without any primary dermatomal involvement in some cases. Oral herpes and genital herpes are the two most common variants.SymptomsEarly symptoms of shingles include headaches, fever and a general feeling of malaise. When an individual's immune system is compromised, such as in older adults or people with cancer undergoing chemotherapy or transplantation, his or her VZV-specific cell mediated immunity also is likely to be impaired, leading to VZV reactivation. The most common complication following herpes zoster infection is postherpetic neuralgia, a persistent pain that can last months to years and occasionally becomes permanent. After that, the infected person experiences a local burning sensation, itching and various levels of pain in the dermatome area. Adjunct therapy for pain and postherpetic neuralgia often is required for patients with herpes zoster. They will form a crust within ten days which will fall off and the skin will recover.Symptoms of herpes include headaches, red sensitive area development, fever and muscle ache. Haser of at the University of Pennsylvania School of Medicine discovered such a protein that is produced during latency and its purpose. Corticosteroids can be also used to treat the infection.To treat herpes, people can use antiviral medication such as acyclovir and valacyclovir. Methods of alternative medicine such as aloe vera lotions or bee products can also be used successfully.
