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. 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. For most people, the pain from shingles resolves as the rash heals, but for others, it can last for months or even years. The virus stays in your body and can later become active again as shingles.As you get older, your chance of developing shingles goes up. ZOSTAVAXA® II is given as a single-dose injection and works by boosting your immune system to help protect you from shingles.
Getting vaccinated can be easy, and the ZOSTAVAXA® II vaccine is available in most clinics, doctorsa€™ offices or pharmacies.
ZOSTAVAXA® II is the only vaccine available to help prevent shingles in individuals 50 years of age or older. ZOSTAVAXA® II does not protect everyone, so some people who get the vaccine may still get shingles. Here's what you need to know about this contagious rash a€“ from phases to complications to vaccines. Shingles is an outbreak of rashes and blisters on the skin, caused by the same virus that causes chickenpox. Research suggests that the vaccine is effective for at least six years, and the vaccine is generally safe and well tolerated.

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. 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.
However, if you develop shingles despite being vaccinated, ZOSTAVAXA® II can help reduce the intensity and duration of pain. This may occasionally be associated with tinnitus, vertigo, deafness, severe otalgia, and inflammation of the pinna. 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. 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.
The condition is caused by reactivation of a latent herpesvirus 3, human infection which causes inflammation of the facial and vestibular nerves, and may occasionally involve additional cranial nerves. 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.
Pain sometimes persists after the rash has gone, more commonly in people over the age of 50. 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.


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. 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. 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. 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.
