After chickenpox the virus remains inactive in certain nerve cells and when it is reactivated it causes herpes zoster. To date it has not been fully clarified which factors lead to reactivation of the virus from its dormant state.
First symptoms of herpes zoster can be burning, itching, tingling or extreme sensitivity of a part of the skin which is most often at one side of the body. Herpes zoster manifests its self mostly on the trunk of the body and on the buttocks of the patient, and rarely on the face, hands and legs.
The most often complication of the herpes zoster is postherpetic neuralgia which manifests in pain, numbness, stinging or itching which continue even after the complete withdrawal of all the changes at the affected area of the skin.

Shingles is initially characterized by the onset of fever, malaise, unilateral pain and tenderness along the course of nerves. Shingles generally affects one side of the torso of the body, the regions around the eyes, or the sides of the neck and the face. Sometimes, even after the normal course of the infection, which is typically in between two weeks to six weeks, the pain can still be experienced. Shingles is not a life threatening condition and typically, the painful conditions and symptoms of Shingles disappear on their own after the duration of the course of the infection is over [1]. While it is well known that it is the same Varicella Zoster virus which causes both chickenpox and Shingles, the exact triggers as to what causes the reactivation of the dormant virus still remains largely unknown. Blisters caused by Shingles are typically only confined to one side of the body and are grouped into clusters in stripes. The Varicella Zoster virus is present in a dormant or inactivated form in the bodies of those individuals who have experienced an episode of chickenpox at some point of time in their lives and also those individuals who have been injected with Varicella vaccine. The reactivation of the Varicella Zoster virus leads to inflammation of the dorsal root ganglia, after which the virus multiples and spreads by travelling along the course of nerves to the superficial nerves of the body, ultimately reaching the surface of the skin. These blisters are both itchy and painful and contain fluids which ooze out over the course of time. Once an individual has encountered chickenpox, even the mildest form of the infection, or once an individual has been vaccinated using the Varicella vaccine, the virus comes to find a presence in the individual’s body.
Immune-suppressive drug therapy: An individual’s body suppresses the Varicella virus in a normal case, thus preventing the reactivation of the virus.
Ageing: With ageing, the immunity of an individual may be lowered and may help Varicella to break from the dormant phase. Psychological stress: Stress is another major cause for suppressing the immunity leading to activity of virus again. Medical conditions like HIV or cancer: Any malignancies or HIV infections may also adversely affect the immune system by lowering the count of white blood defense cells in the body. Stress: Acute trauma or stress may also prove to give a sudden shock to the immune system and may lead to the reactivation of the dormant Varicella virus.
Medications: Certain medications which are prescribed after an individual has undergone an organ transplant so that the body does not reject the foreign organ require suppressing the immune system by a great deal. Family History: It is often the case that an individual who has experienced an episode of Shingles will have many other family members who have also encountered the disease.
Bone Marrow Transplants: Bone marrow transplants leave the state of the immune system of the body highly weakened and defenseless. Anybody who has encountered even the mildest of chickenpox infections is at a risk to developing Shingles. While the exact mechanism of how the virus is reactivated from its dormant state and what actually proves to be the trigger, external or internal is still far from being understood, the risk factors of the causes of Shingles are generally widely agreed upon.
If an individual is suspected to be facing a risk factor to encountering Shingles, proper medical consultation must be sought at the earliest.
Shingles is a contagious disease and it may spread to other individuals through direct body contact through the fluid filled blisters or the unhealed sores and wounds where scab is yet to form. A person who has been vaccinated against chickenpox or one who has encountered chickenpox earlier in life cannot develop Shingles through transmission by body contact.
If an individual is not vaccinated against chickenpox and Shingles, it must be done at the earliest in order to prevent encountering the contagious disease. In case there is oozing from the rashes and blisters and fluid comes out of the skin lesions, it is recommended to take the day off and to abstain from school or work.
It is always advised to cover all the blisters and rashes if meeting other individuals so as to prevent the virus from spreading.
Herpes zoster is characterised by painful erruptions (yellowish fluid filled) in a linear shape over limited area of body like face, eyes, genitals and other body parts. Same presentation of the Herpes eruption can also be noted on genitals in male and females also. Herpes Zoster is known to leave behing a painful conditon called Post-herpetic Neuralgia in many patients. Virus can be detected by investigations of variety of body fluids such as eye secretions, mouth secretions, blister fluid, genital secretions, urine and blood and in very sick patients, the cerebrospinal fluid. Antiviral, Analgesics and steroids are the treatment that may help little in some patients but can not kill this horrible virus from within. Steroids have their own set of side effects on Blood sugar, blood pressure, bone mass, body weight etc. Herpes zoster (or simply zoster), commonly known as shingles and also known as zona, is a viral disease characterized by a painful skin rash with blisters in a limited area on one side of the body (left or right), often in a stripe.
Reactivation of varicella-zoster virus (VZV) that has remained dormant within dorsal root ganglia, often for decades after the patient’s initial exposure to the virus in the form of varicella (chickenpox), results in herpes zoster (shingles). A person with shingles can pass the varicella-zoster virus to anyone who isn’t immune to chickenpox.
The signs and symptoms of shingles usually affect only a small section of one side of your body. Most commonly, the shingles rash develops as a stripe of blisters that wraps around either the left or right side of your torso.

The aims of treatment are to limit the severity and duration of pain, shorten the duration of a shingles episode, and reduce complications. The statistics show that about 20% of the persons who had chickenpox will have herpes zoster.
Temporary weakness of the immune system can cause the virus to multiply and spread across the nerves to the surface of the skin. A special care is necessary in patients who have their eyes infected by herpes zoster, because permanent damage is possible if adequate treatment is not provided in time. Based on the dermatologist’s assessment, the fluid in the blisters can be sent to special laboratory tests.
If the disease is diagnosed in the early phase, antiviral medication can be prescribed which will prevent further propagation and spreading of the virus. It is seen to be more common in adults and more so in the case of males as compared to females. It later leads to vesicular type of painful rashes along the course of the affected nerves. Sometimes, the infection may go unnoticed as there is no appearance of blisters, but there is only the pain that can be felt. Typically, the duration of an episode of Shingles infection can last for anything in between two weeks to six weeks. The virus is a double stranded DNA virus that leads to development of the painful condition.
If an individual encounters an episode of chickenpox in his lifetime, even after the disease has long been treated and forgotten about, the virus remains dormant in some parts of the body, especially the dorsal root ganglia cells present in the spinal cord and in the brain.
However, it can also be seen that the risk of encountering Shingles is greater as an individual ages or in those undergoing cancer treatment, leading to the widely agreed upon belief that a weakening of the immune system can be linked to the conditions of reactivation of the dormant virus. While they typically manifest on one side of the torso or the waistline, they may also infect one side of the face, one side of the neck, or even the region around one eye.
The Varicella Zoster virus remains inactive in the dorsal root ganglia cells and other nerve cells without causing any noticeable effects in the body until it is reactivated by an external or internal stimulus [3]. On reaching the superficial nerves, they further lead to the development of painful rashes and blisters in form of stripes.
Medical examination has revealed that the blisters also contain the Varicella Zoster virus. While chickenpox is more closely associated with childhood and early adulthood, Shingles is associated with elderly age, even though the same virus is what causes both of these diseases.
However, the lack of proper immunity in the case of immune-compromised individuals, may lead to reactivation and also outbreak of the virus in a much more vigorous form. Studies have also revealed that many experts believe that after the age of 80, half of the total number of people will encounter Shingles. It is recommended to always keep the body healthy and to keep stress levels in check in order to avoid an outbreak of the Varicella virus.
It is often the case that patients who are diagnosed with cancer and are undergoing therapy may face an episode of Shingles. Alongside chemotherapy, Shingles is most commonly encountered by cancer patients undergoing radiation therapy. Even if the condition is mild, if encountered, Shingles can affect the normal development of the baby as well. Individuals who have recently undergone a transplant surgery are at a high risk of developing Shingles. However, even those people who have been injected with the Varicella vaccine have the virus present in their body and as such, are also at a higher risk to encountering the condition than a normal individual who has never been vaccinated or has suffered from chickenpox.
An early diagnosis may lead to a speedier recovery and will also prevent the chances of complications. This means that before the appearance of blisters and after the drying up of the sores on the surface of the skin, Shingles cannot be transmitted contagiously.
Direct body contact with the fluid coming out of the oozing sores is what can cause the virus to be transmitted to another individual.
Anybody suffering from Shingles should make sure never to share clothes or towels with other individuals, should avoid swimming in public areas and also should avoid playing any sports which involve contact.
While the condition can be really painful and irritating, sufferers will also need to maintain care from their end so as to prevent spreading the virus to other individuals. Rajesh Shah has treated patients from every state and city in the United States, from every European, Asian and African country.An overwhelming experience, indeed. Transmission may also occur directly, or through contact with infected razors, towels, dishes, and other shared articles.
The initial infection with varicella zoster virus (VZV) causes the acute, short-lived illness chickenpox which generally occurs in children and young adults. Although it is usually a self-limited dermatomal rash with pain, herpes zoster can be far more serious; in addition, acute cases often lead to postherpetic neuralgia (PHN).
Shingles in or around an eye (ophthalmic shingles) can cause painful eye infections that may result in vision loss. Depending on which nerves are affected, shingles can cause an inflammation of the brain (encephalitis), facial paralysis, or hearing or balance problems. Newborns and persons with a significantly decreased immunity are at great risk of catching chickenpox from a person that has herpes zoster. In more severe cases and when the eye is caught in the infection, the dermatologist prescribes a combination of systemic corticosteroids and antiviral medication. These are usually fluid filled vesicles that may rupture in due course of time for the commencement of healing. In such cases, diagnosis of the disease becomes difficult as the pain may be mistaken to be caused by something else. In such cases, damaged nerves tend to send out false signals and also greatly exaggerated signals of pain being experienced, even when the infection may have long subsided. An early diagnosis of the signs and symptoms of Shingles may help in achieving a speedier recovery.

While the Varicella Zoster virus is similar to the Herpes Simplex Virus and both belong to the same family, they prove to have different actions and cause different signs and symptoms in individuals. If the dormant virus is reactivated due to some external or internal trigger, then Shingles will be developed by the individual. In such cases, special care must be taken as the blisters may easily damage the optical nerve, leading to permanent eye damage and even loss of vision. While the immune system of a normal individual proves to suppress the reactivation of the virus, individuals in whom the immune system is weakened or compromised may suffer from reactivation of the dormant virus. Thus the virus, which had once affected an individual early on in life, remains dormant for a lengthy course of time until reactivated.
It is often seen that the use of drugs such as corticosteroids may lead to immune system suppression. While there is no real treatment method for Shingles, there are many medications which can help prevent the virus from spreading and many others help in alleviating the pain associated with the blisters.
It is always advised to keep the blisters covered and to avoid contact when suffering from the condition.

Once an episode of chickenpox has resolved, the virus is not eliminated from the body and can go on to cause herpes zoster often many years after the initial infection. Depending on the location of the pain, it can sometimes be mistaken for a symptom of problems affecting the heart, lungs or kidneys.
However, a study on untreated herpes zoster shows that, once the rash has cleared, postherpetic neuralgia is very rare in people under 50 and wears off in time; in older people the pain wore off more slowly, but even in people over 70, 85% were pain free a year after their shingles outbreak. This condition is known as postherpetic neuralgia, and it occurs when damaged nerve fibers send confused and exaggerated messages of pain from your skin to your brain. Pain sometimes persists after the rash has gone, more commonly in people over the age of 50.
Very quickly, on top of the present redness there appear grouped blisters which last two to three weeks. There may also be tingling, itching or prickling type of sensation in the affected nerves or rashes. Most people only face a single episode of Shingles in their entire lifetime but in some cases in which the immunity of the body is greatly lowered, individuals may experience multiple outbreaks of the virus and multiple episodes of Shingles. As soon as it is reactivated, the virus multiplies at great speeds and spreads to the surface of the skin from where on it may prove to be transmitted contagiously on to another person.
Again resistance develops and the cycle continues till patient starts getting severe side effects. Constitutional medicines reduce the intensity of pain, burning and subsequently reduce infection, and shorten the duration of infection. Herpes zoster is not the same disease as herpes simplex, despite the name similarity; both the varicella zoster virus and herpes simplex virus belong to the same viral subfamily Alphaherpesvirinae. Nevertheless, it is still extremely rare to experience more than three outbreaks of the disease.
Even though both the virus types belong to the herpes family, The Varicella Zoster virus does not cause herpes or other transmitted diseases such as cold sores. Very rarely, herpes zoster can manifest it self only in pain and without blisters, or with blisters but with no sense of pain. A slight weakening of the immune system in older people may account for the virus reactivating and multiplying to cause shingles.) Shingles is also more common in people with a poor immune system (immunosuppression).
The rash looks like chickenpox, but only appears on the band of skin supplied by the affected nerve.
The soft tissues under and around the rash may become swollen for a while due to swelling (inflammation) caused by the virus.
In this person, it has affected a nerve and the skin that the nerve supplies, on the left side of the abdomen. In severe cases it can lead to inflammation of the whole of the eye which may cause loss of vision.
People with a poor immune system (immunosuppression) who develop shingles have a higher than normal risk of developing rare or serious complications.
Pain may be eased by cooling the affected area with ice cubes (wrapped in a plastic bag), wet dressings, or a cool bath. A non-adherent dressing that covers the rash when it is blistered and raw may help to reduce pain caused by contact with clothing. An antiviral medicine does not kill the virus but works by stopping the virus from multiplying.
It had also been hoped that antiviral medicines would reduce the risk of pain persisting into PHN. However, the research so far has shown that the current antiviral medicines taken during an episode of shingles do not seem to have much impact on the prevention of PHN. Further research is needed in this area to determine if certain groups of patients do benefit and if newer antiviral drugs can prevent PHN. For example, young adults and children who develop shingles on their tummy (abdomen) very often have mild symptoms and have a low risk of developing PHN. In addition to easing pain during an episode of shingles, they may also help to prevent PHN. You will normally be given antiviral medication whatever your age, and will be monitored for complications.
