The varicella zoster virus is a type of herpes simplex virus (HSV) but is not the same as the herpes simplex virus that causes genital herpes. Herpes zoster is not a virus but a syndrome that arises with reactivation of the varicella zoster virus (VZV) years or even decades after chickenpox.
Herpes zoster is the same as shingles, an alternative and commonly used name for this condition. Herpes zoster is more likely to occur in a person with a depressed immune system and the elderly.
Herpes zoster, commonly known as just zoster or shingles, is a condition caused by the reactivation of the varicella zoster virus (VZV). Shingles is the syndrome where a painful skin rash marked by the presence of tiny blisters usually forms on a dermarcated area on the skin surface of the head or trunk. Once the virus reactivates, it causes inflammation of the nerves and is therefore also known as acute posterior ganglionitis.
However, shingles often arises for no known reason even in a person without any of these contributing factors. Images from CDC (1)The main symptoms of herpes zoster (shingles) is an itchy skin rash and pain which has been discussed in detail below. Herpes zoster mainly affects sensory nerves but motor nerves that control muscles may also be affected.
Pain that lasts for longer than a month, even after the rash clears, is most likely a complication of shingles known as post-herpetic neuralgia. All images have been sourced from the Dermatology Atlas (2) courtesy of Samuel Freire da Silva, M.D. Tricyclic antidepressants, anticonvulsants and corticosteroids along with anesthetics may be needed for post-herpetic neuralgia. Treatment should be commenced immediately once a diagnosis of shingles is made, preferably within the first few days of the onset of the rash. Zoster vaccine to prevent shingles and should be considered only for a person older than 60 years of age.

Herpes zoster, also referred to as Shingles, causes pain and often causes a blistering skin rash. Most cases of chickenpox occur in people who are younger than 15 years of age, but adults can also get chickenpox.
Herpes zoster causes pain, tingling, or itching and often causes a rash that can appear in a band, a strip, or a small area. Symptoms for herpes zoster may also include headache, fever, chills, abdominal pain, joint pain, muscle weakness, hearing loss, and genital lesions. Pain associated with shingles usually lasts for 2 to 3 weeks, but can last for months, even years.
After you have chickenpox, the virus that causes it remains inactive (dormant) in your body inside certain nerve cells. Antiviral medications such as acyclovir, valacyclovir, and famciclovir may be prescribed by your doctor. Herpes zoster is usually easily diagnosed by your health care provider by visual examination and acknowledging chickenpox history.
Some individuals may experience shingles or chickenpox-like rashes within 42 days after receiving zoster vaccine.

AbstractThis review of the data from the Shingles Prevention Study (SPS) highlights the efficacy and safety of a high-titer live attenuated herpes zoster virus vaccine in preventing herpes zoster and postherpetic neuralgia (PHN) in adults aged 60 years or older. Prevention of herpes zoster in older adults has been recognized as a medical priority for many reasons. The antiviral and corticosteroid drugs traditionally used to treat patients for acute herpes zoster episodes provide limited efficacy in preventing these problems.
The US Food and Drug Administration's recent approval of a live attenuated vaccine to prevent herpes zoster in individuals aged 60 years or older has the potential to greatly reduce the burden of herpes zoster and its complications, including PHN, in this age group. Recognition of the impact of herpes zoster on adults led to the development of a much more potent formulation of the currently available childhood chickenpox (varicella) vaccine. The SPS was a randomized double-blind placebo-controlled trial designed to evaluate the efficacy and safety of the zoster vaccine in preventing the occurrence of herpes zoster, as well as its most common complication, PHN.17 The study was conducted at 22 study sites across the United States and enrolled 38,546 adults aged 60 years or older with no prior cases of herpes zoster, but with a history of varicella or who resided in the United States for at least 30 years. When subjects were stratified according to age or sex, the vaccine was slightly more effective in the younger age group of those enrolled. The secondary outcome in this study was the impact of active vaccine versus placebo on the rate of PHN among subjects with confirmed herpes zoster disease. Overall, the number and types of serious adverse events were similar whether subjects received placebo or active vaccine. During the 42 days post injection, seven cases of confirmed zoster were recorded in the vaccine group compared with 24 occurring among placebo recipients. An adverse event substudy involving 3345 patients receiving vaccine and 3271 receiving placebo was carried out for the purpose of a more intensive safety evaluation via daily logs for adverse events, a report card of symptoms for 42 days after injection, and follow-up for subsequent hospitalizations.
The zoster vaccine is indicated for the prevention of herpes zoster in adults aged 60 years and older. The positive outcomes among vaccine-treated individuals suggest that the herpes zoster vaccine boosts CMI, thereby protecting vaccinated subjects against reactivation of VZV lying dormant in the dorsal root ganglion.
The SPS established the ability of the new zoster vaccine to prevent herpes zoster and its most common complication, PHN, and to reduce the severity of herpes zoster in adults aged 60 years or older. Persons using assistive technology might not be able to fully access information in this file. The triggers for reactivation of VZV have not been identified and probably involve multiple factors. Zoster rash is typically unilateral and does not cross the mid-line, erupting in one or two adjacent dermatomes.

The frequency of zoster occurrence in different dermatomes has been evaluated in certain studies.
Regardless of definition, the pain of PHN can last for weeks or months and occasionally persists for many years. The prognosis for these conditions is good, although encephalomyelitis can be life threatening. The risk for neurologic zoster complications is generally increased in immunocompromised persons.
VZV can be transmitted from zoster lesions to cause primary varicella in susceptible persons. Finally, one study indicated that dietary micronutrient intake was protective against zoster. Despite these limitations, certain analyses of zoster incidence in the United States have been conducted. Zoster vaccination is not recommended for persons of any age who have received varicella vaccine.
Persons with clinical or laboratory evidence of other unspecified cellular immunodeficiency. Persons receiving recombinant human immune mediators and immune modulators, especially the antitumor necrosis factor agents adalimumab, infliximab, and etanercept.
The Immunization Action Coalition (IAC), a non-profit organization, works to increase immunization rates and prevent disease by creating and distributing educational materials for health professionals and the public that enhance delivery of safe and effective immunization services.
After the active phase of the infection resolves, the virus stays dormant at the spinal nerve root, specifically the dorsal root ganglion. It mainly affects the sensory nerves but can sometimes involve the motor nerves – those nerves that control muscles in the body. These symptoms usually settle after 10 to 15 days but can take up to one month to resolve completely.
This gives rise to symptoms such as paralysis of the diaphragm, bladder and bowel problems, cranial nerve palsies and muscle weakness. A dermatome is an area of the skin which is innervated by nerves from a single spinal root. However, if the infection occurs in a vaccinated person it is usually less severe and shorter in duration. You can get chickenpox from touching the fluids from a chickenpox blister, or if someone with chickenpox coughs or sneezes near you. If shingles affects a nerve in your face, a rash involving different parts of your face can cause drooping eyelid, loss of eye motion, difficulty moving some of the muscles in the face, or blindness. When the nerves have been damaged from shingles, postherpetic neuralgia (PHN) can occur, and the resulting pain can be mild to very severe.
Shingles, Herpes Zoster, occurs after the virus becomes active again in these nerves years later.
If an adult or child has direct contact with the fluid from the shingles rash blisters and has not had chickenpox as a child or has not had a chickenpox vaccine, they can develop chickenpox, rather than shingles.
In 2006, the United States Food and Drug Administration approved Zostavax for the prevention of shingles. The most common complication is postherpetic neuralgia, which is persistent nerve pain after the rash disappears.There is a vaccine available to help prevent shingles for certain individuals. Although the incidence of zoster is relatively low in young people, the incidence of zoster increases dramatically after age 50 years.
Surveillance was further ensured by a well-defined interactive and automated telephone-response system, which participants called monthly.
This end point was defined as a composite measure of incidence, severity, and duration of zoster-related pain and discomfort.
In the Shingles Prevention Study, the burden of illness (BOI) score for herpes zoster was significantly reduced among subjects who received the active vaccine compared with those receiving placebo. In total, there were 107 cases of PHN among study subjects: 27 in the vaccine group and 80 in the placebo group. It is contraindicated in individuals who are immunocompromised because of leukemia, lymphoma, malignant neoplasms of the bone marrow or lymphatic system, because of AIDS, or because of receiving high doses of corticosteroids.
The cumulative incidence of postherpetic neuralgia among subjects who received the active vaccine in the Shingles Prevention Study remained significantly below that of subjects receiving placebo for up to 5 years.
If appropriately implemented, the zoster vaccine could prevent the occurrence of as many as a quarter of a million cases of zoster in US adults 60 years of age and older.17 The vaccine would also significantly reduce the BOI in others in whom herpes zoster develops after vaccination by resulting in less severe acute herpes zoster as well as decreased incidence of PHN.
The Advisory Committee on Immunization Practices recommends the use of the herpes zoster vaccine in all adults aged 60 years or older.
This report provides recommendations for use of zoster vaccine for prevention of zoster and its sequelae. Zoster also can result in autonomic dysfunction, causing urinary retention and colon pseudo-obstruction. A prospective cohort study indicated a nonsignificant association (p = 0.078) between zoster risk and negative life events. In addition, no evidence existed of transmission of vaccine virus from vaccine recipients to contacts. Approximately 1%--4% of zoster episodes result in hospitalization, with a mean duration of 4.8 days. Many of these cases cause debilitating pain, and when PHN develops, the pain can last for months or even years. IAC also facilitates communication about the safety, efficacy, and use of vaccines within the broad immunization community of patients, parents, healthcare organizations, and government health agencies. Shingles can affect any age group but is more commonly seen in the elderly and those with depressed immune defenses. Although the peripheral nerves to the trunk is commonly affected, the virus may cause inflammation of any part of the nervous system, even the brain (encephalitis), meninges (meningitis) or both (meningoencephalitis). There is a vaccine that can prevent chickenpox in up to 90% of people who receive the vaccine.

Then red patches may appear, followed by small blisters in a band, a strip, or a small area. As people get older, they are more likely to develop PHN, and the pain is more likely to be severe. Herpes zoster may develop in any age group, but you are more likely to develop the condition if you are older than 50 years of age or have a weak immune system. Zostavax is a more concentrated formulation of the Varivax vaccine, used against chickenpox. In addition, vaccination was associated with a 51.3% reduction in the overall incidence of herpes zoster.
Of this population, 46% were at least 70 years old and more than 6.5% were aged 80 years or older.
Study subjects who were suspected to have herpes zoster or who failed to call their study site, were contacted for follow-up. Pain was assessed using the Zoster Brief Pain Inventory, a questionnaire that patients answered after the onset of herpes zoster to measure their zoster-associated pain and discomfort. There were five serious adverse events considered possibly related to the vaccine, though only two of these occurred in patients who received active treatment compared with three in the placebo group.
Based on the results of the SPS, the vaccine promises to significantly reduce the health and economic burden of illness associated with herpes zoster disease in the United States.26 However, these benefits will not be attained unless physicians and other healthcare providers actively educate their patients about the disease and offer the vaccine to appropriate individuals. The varicella zoster virus causes the common childhood infection known as chickenpox which resolves after a few weeks. The virus targets certain nerves with symptoms such as the rash and pain being isolated to those areas of the skin supplied by a single spinal nerve. The rash usually involves a narrow area from the spine around to the front of the belly area or chest. Antihistamines, soothing baths, wet compresses, and lotions, such as colloidal oatmeal bath, starch baths, or calamine lotion can reduce itching.
Doerr received his undergraduate degree in Spanish from the University of Colorado at Boulder. The diagnosis of herpes zoster was based on established clinical and laboratory features, and associated pain and discomfort were assessed repeatedly for at least 6 months after diagnosis.
The numerical value of the patients' BOI was plotted over time, and a score was derived from the area under the curve of these values.
However, the virus remains dormant for long periods of time in the body and may sometimes reactivate to cause inflammation of the nerve roots.
Although shingles resolves within a month, it can sometimes lead to complications or the pain can persist for months thereafter (post-herpetic neuralgia).
The greatest incidence of zoster in the non-HIV-infected population occurs between ages 50 and 80. So, you can't catch shingles from someone, but someone with shingles can spread chickenpox to another person who hasn't had chickenpox and who hasn't gotten the chickenpox vaccine. Older adults who receive the herpes zoster vaccine are not as likely to have as many complications from shingles. He graduated with his Medical Degree from the University Of Colorado Health Sciences Center in Denver, Colorado in 1998 and completed his residency training in Emergency Medicine from Denver Health Medical Center in Denver, Colorado in 2002, where he also served as Chief Resident. Cunha's educational background includes a BS in Biology from Rutgers, the State University of New Jersey, and a DO from the Kansas City University of Medicine and Biosciences in Kansas City, MO.
The vaccine was safe in the SPS population, with little differentiation from the safety profile of placebo other than an increased risk for reactions at the injection site. The secondary end point was the incidence of PHN, determined by pain persisting beyond 90 days from onset of the zoster rash. This does not happen in every person who had chickenpox and is more frequently seen in diminished immune states. Vaccines provide an effective albeit not guaranteed protection against developing shingles.
The blisters break, forming small ulcers that begin to dry and form crusts that fall off in 2 to 3 weeks. Zoster in HIV-infected patients, however, occurs more frequently than would be expected in the age groups studied. He completed residency training in Emergency Medicine at Newark Beth Israel Medical Center in Newark, New Jersey. Rates of serious adverse events, systemic adverse events, hospitalization, and death were low and similar to those observed in the group that received placebo.
Those who take immunosuppressive drugs after organ transplantation are also at greater risk of getting shingles.
If you have had the chickenpox vaccine, you are less likely to get chickenpox and therefore less likely to develop shingles later in life.
