Clinical Overview of Herpes Zoster (Shingles)

Cause

Herpes zoster, also known as shingles, is caused by reactivation of varicella-zoster virus (VZV), the same virus that causes varicella (chickenpox).

Primary infection with VZV causes varicella. After a person has varicella, the virus remains latent in the dorsal root ganglia. VZV can reactivate later in a person’s life and cause herpes zoster, a painful maculopapular and then vesicular rash.

Clinical Features

People with herpes zoster most commonly have a rash in one or two adjacent dermatomes. The rash most commonly appears on the trunk along a thoracic dermatome or on the face and it usually does not cross the body’s midline.

The rash is usually painful, itchy, or tingly. A person can experience the following symptoms several days before the rash appears:

• Headache
• Photophobia (sensitivity to bright light)
• Malaise

The rash develops into clusters of vesicles. New vesicles continue to form over 3 to 5 days, and the rash progressively dries and scabs over. The rash usually heals in 2 to 4 weeks. Permanent skin discoloration and scarring can occur.

Complications

Postherpetic neuralgia (PHN)

PHN is the most common complication of herpes zoster. PHN is pain that persists in the area where the rash once was located and continues more than 90 days after rash onset. PHN can last for months or even years.

A person’s risk of having PHN after herpes zoster increases with age. Older adults are more likely to have longer lasting, more severe pain. Approximately 10% to 18% of people with herpes zoster will have PHN. PHN is rare in people younger than 40 years old. The likelihood of PHN is also higher in people who experience more pain with the rash or have a large rash.

Herpes zoster ophthalmicus

Herpes zoster that affects the ophthalmic division of the trigeminal nerve is called herpes zoster ophthalmicus. This can result in acute or chronic ocular sequelae, including vision loss.

Disseminated zoster

Disseminated zoster can include generalized skin eruptions where the lesions occur outside of the primary or adjacent dermatomes. It can be difficult to distinguish from varicella. Visceral involvement of the central nervous system (meningoencephalitis), lungs (pneumonitis), and liver (hepatitis) can also occur. Disseminated zoster generally occurs in people with compromised or suppressed immune systems.

People with compromised or suppressed immune systems are more likely to have a severe, long-lasting rash and experience more severe complications from herpes zoster.

Vaccination

Recombinant zoster vaccine (RZV, Shingrix) is the recommended vaccine to prevent shingles and related complications. For information about vaccination recommendations see Shingles Vaccination.

Transmission

People with active herpes zoster lesions can spread VZV , which causes varicella in people who never had varicella or never received varicella vaccine. Once varicella resolves, these people would be at risk for herpes zoster.

Active herpes zoster lesions are infectious through direct contact with vesicular fluid or through breathing in virus particles from the blisters until they dry and scab over. People with active herpes zoster lesions should cover their lesions and avoid contact with susceptible people in their household and in occupational settings until their lesions are dry and scabbed.

Epidemiology

Risk Factors

Anyone who had varicella can develop herpes zoster. Approximately 99.5% of people born before 1980 in the United States were infected with wild-type VZV. Children who receive varicella vaccine have a lower risk of herpes zoster compared with children who were infected with wild-type VZV.

Approximately 1 in 3 people in the United States will develop herpes zoster during their lifetime. Most people have only one episode; however, herpes zoster can recur.

A person’s risk for herpes zoster and related complications sharply increases after 50 years of age. The reasons why VZV reactivates and causes herpes zoster are not well understood. However, a person’s risk for herpes zoster increases as their VZV-specific cell-mediated immunity declines. This decline in immunity can result from increasing age and medical conditions or medications that suppress a person’s immune system. People with the following conditions that compromise or suppress their immune system have an increased risk for herpes zoster:

• Bone marrow or solid organ (renal, cardiac, liver, and lung) transplant recipients
• Cancer, especially leukemia and lymphoma
• Human immunodeficiency virus (HIV)
• Taking immunosuppressive medications, including steroids, such as for treatment of autoimmune diseases and other immune system deficiencies

Other potential risk factors for herpes zoster have been identified, but the findings are either inconsistent or unexplained. For example:

• More women than men develop herpes zoster.
• Herpes zoster is less common in Blacks than in Whites.

Disease Rates

An estimated one million cases of herpes zoster occur annually in the United States.

• The incidence of herpes zoster varies by age and is approximately 2–9 cases per 1,000 US population annually.

The precise incidence of recurrence is not known.

Complications

• Approximately 10% to 18% of people with herpes zoster will have PHN.
• Approximately 1% to 4% of people with herpes zoster are hospitalized for complications.
• Older adults and people with compromised or suppressed immune systems are more likely to be hospitalized. About 30% of people hospitalized with herpes zoster have compromised or suppressed immune systems.

Deaths

One study estimated 96 deaths occur each year where herpes zoster was the underlying cause (0.28 to 0.69 per 1 million population). Almost all the deaths occurred in older adults or those with compromised or suppressed immune systems.

Trends

Herpes zoster rates among adults in the United States gradually increased over a long period of time. We do not know the reason for this increase. However, the rates across age groups have recently plateaued or declined.

CDC studies have found that herpes zoster rates started increasing before varicella vaccine was introduced in the U.S. and did not accelerate after the routine varicella vaccination program started.

Herpes Zoster in People Who Received Varicella Vaccine

Varicella vaccines contain live attenuated VZV, which results in latent infection. Although herpes zoster has always been uncommon among children, the rate of herpes zoster in U.S. children has declined since the routine varicella vaccination program started in 1996.

• Children (healthy and immunocompromised) vaccinated against varicella have lower rates of herpes zoster compared to children who had natural infection with varicella.
  • Vaccinated children are less likely to become infected with wild-type VZV.
  • The risk of reactivation of vaccine-strain VZV in children is lower compared with reactivation of wild-type VZV.
• Few older adults have received the varicella vaccine since it was licensed in 1995. There is very little information on the risk of herpes zoster in people who got varicella vaccine as adults.

CDC continues to monitor the impacts of the U.S. varicella and herpes zoster vaccination programs among adults and children.

What Causes Shingles to Activate and What to Do About It

People over 50 are most susceptible to developing shingles as the primary risk factor for shingles is a weakened immune system.

If you contract the chickenpox virus, also known as varicella-zoster, your illness will typically clear up in a week or two. However, this virus remains in your body even after you’ve recovered.

The virus lies dormant when your immune system is strong. But if something causes you to become immunocompromised, the virus can reactivate. This triggers shingles.

Shingles, known by its medical name herpes zoster, presents as a painful rash. It typically shows up on only one side of your body.

According to the Centers for Disease Control and Prevention (CDC), the chance of getting shingles at some point in your life is 1 in 3.

When you first contract the varicella-zoster virus (VZV), you’ll get chickenpox. When you fight off this virus, your body creates immunity to it, so it’s very rare to get chickenpox a second time.

However, that doesn’t mean that your body rids itself of the virus entirely. Though a strong immune system will keep the virus inactive, it’s still there for the rest of your life.

If your immune system becomes weakened or compromised, it’s possible for this virus to reactivate. A painful shingles rash may result.

Prior to the development of the varicella vaccine, chickenpox was a common childhood illness. Most people were exposed to VZV in childhood and developed chickenpox in their younger years.

In fact, doctors once encouraged families to expose their kids to chickenpox at an early age — after age 10 or so, the disease can be much more severe. (You may remember “chickenpox parties,” where parents actively tried to get their children to contract the virus.)

Adults who come down with chickenpox can experience serious and even life threatening complications like lung or brain infections.

These days, children and adults can receive the varicella vaccine. This weaker version of the live virus causes the body to launch an immune response so that it recognizes — and fights off — VZV in the future.

Getting a varicella vaccine appears to reduce the risk of shingles, but it isn’t a guarantee against them. Though weakened, the virus does continue to stay in your body, so it’s possible for it to reactivate and cause shingles. However, this is uncommon.

One study found that the rate of shingles infection was 78 percent lower in vaccinated children than unvaccinated children.

The varicella vaccine became available in 1995, so only time will tell its effects on the rates of shingles in older adults.

If you’ve had chickenpox or gotten the varicella vaccine, you can develop shingles.

According to the CDC, over 99 percent of people in the United States born before 1980 have had chickenpox or been exposed to VZV.

The primary risk factor associated with getting shingles is a weakened immune system. When your immune system isn’t functioning properly, VZV can reactivate.

As you age, your immune system doesn’t fight off invaders as well. Older age is associated with greater likelihood of health problems, including:

• a natural decline in immunity
• the use of immunosuppressant medications like chemotherapy, long-term corticosteroids, and anti-inflammatory medications
• certain diseases and conditions that damage your immune system, such as HIV and hypogammaglobulinemia
• autoimmune diseases that are treated with immune-suppressing drugs, such as rheumatoid arthritis, Crohn’s disease, and lupus
• procedures like bone marrow transplants and kidney transplants, which may require treatment with immunosuppressants afterward

Starting around age 50, your chance of getting shingles goes up. The severity of the disease and the risk of complications also increase with age.

It’s important to remember, too, that stress can negatively affect your immune system. There’s been some interest in whether stressful life circumstances could weaken the immune system, leading to a shingles infection. However, research is contradictory and doesn’t yet offer firm conclusions.

Shingles isn’t a disease you “catch” in the traditional sense. It’s usually a case of VZV reactivating in your system. But people who’ve never had chickenpox can develop shingles after coming into contact with the fluid from shingles blisters. Shingles are no longer contagious after these blisters have crusted over.

Typically, shingles shows up as a painful rash on an area of skin that is supplied by a single nerve. This area, regardless of its location on the body, is known as a dermatome. Look for these hallmarks of a shingles rash:

• A band of blistering lesions may cover red, inflamed skin, often on one side of the torso or face.
• Pain starts out feeling tingly or burning. Other common sensations include itching and numbness.
• The pain progresses in severity over several days.
• It feels like the pain is coming from the organs in your abdomen, like your heart, gallbladder, appendix, or kidneys.
• Sometimes (though rarely) people experience severe pain without a rash, known as zoster sine herpete.

Some people also have other, more general symptoms, like:

• fever
• chills
• headache

Shingles symptoms can last up to 4 weeks or longer.

To diagnose shingles, your doctor will ask you some questions about your symptoms. These may include:

• When did your symptoms start?
• Which symptom did you notice first?
• Are you experiencing pain?
• Where are you having pain?
• Have you had chickenpox?
• Have you had the chickenpox vaccine?
• Have you had the shingles vaccine?

They’ll also evaluate your rash, looking at its pattern, appearance, and location. Doctors can usually diagnose shingles by its distinctive rash and unique symptoms.

In rare cases, though, if your doctor is uncertain whether you have shingles, you may undergo a diagnostic test. Testing is more common for people with greater risk factors for complications, including:

• people with a weakened immune system
• pregnant people
• newborns

To test for shingles, your doctor will use a swab to take a sample from a skin lesion. This will then be tested for VZV. A positive test indicates that you have shingles.

How to feel better if you have shingles

When you have shingles, you can feel better by trying the following:

• Eat a balanced diet, get lots of rest, and try some gentle exercise.
• Relieve pain and itching by soaking in a bathtub of lukewarm water and ground-up oatmeal.
• Reduce pain and promote healing of lesions by applying a cool, wet washcloth or compress to the rash.
• Do what you can to limit stress. A stressful lifestyle can weaken your immune system, worsening your symptoms.
• Wear loose-fitting clothes that won’t irritate the rash.
• Keep the lesions covered with a bandage. Prior to putting on the bandage, apply a thin layer of petroleum jelly to prevent irritation.

Although there’s no cure for shingles, the good news is that it resolves on its own. Your doctor may recommend certain medications to alleviate pain or treat infection.

Antiviral medication

Three antiviral medications are used to treat shingles:

• valacyclovir
• famciclovir
• acyclovir

Valacyclovir and famciclovir are taken three times per day. They’re usually preferred over acyclovir, which must be taken five times a day.

All three have a 7-day course if you have an uncomplicated case of shingles. If the shingles is complicated — if it’s affecting your eyes, for example — your doctor will prescribe the medication for longer than 7 days.

Antiviral medication can help:

• you recover faster
• limit the severity of your symptoms
• reduce your risk for complications

Antiviral medications offer the most benefit for people over 50 and those who are immunocompromised, since these risk factors are associated with more persistent, severe shingles symptoms.

It’s best to start an antiviral while you’re still developing new skin lesions, usually within 72 hours of noticing your first symptom. Antivirals won’t be effective after your lesions have begun to crust over.

Some people may need to take a longer course of antiviral medications or even be treated in the hospital with antivirals. This is more likely if you have the following:

• a weakened immune system
• a severe case of shingles
• a high risk of complications

Some people experience shingles on the face. This can lead to serious complications, such as:

• blindness
• hearing impairment
• brain swelling

Seek immediate medical attention if you think you have shingles on your face.

Pain medication

Mild shingles pain may improve with over-the-counter anti-inflammatory medications. Your doctor may recommend ibuprofen or acetaminophen or weak opioids, such as codeine or tramadol.

Stronger prescription opioid pain medication, such as hydrocodone, may be prescribed to treat moderate to severe shingles pain.

Another option is topical pain relievers, such as lidocaine. These are applied directly to your skin for relief. You can find topical pain relievers as ointments, creams, gels, sprays, or patches. Capsaicin, which comes in a cream or a patch, may also be helpful.

Other medications that may be used for relief include:

• diphenhydramine
• hydroxyzine
• calamine lotion to soothe itching
• antibiotics, if a bacterial infection develops around the rash

Shingix (recombinant zoster vaccine) is currently the only shingles vaccine available in the United States. It’s given to people over age 50.

Previously, an additional vaccine, Zostavax, was used, but it was phased out in the United States as of November 2020.

According to the CDC, two doses of Shingrix are over 90 percent effective at preventing shingles. You’ll retain at least 85 percent protection for 4 years after being vaccinated.

If you get shingles after being vaccinated, your symptoms will likely be less severe. You’ll also have a lower chance of developing postherpetic neuralgia — a complication where pain remains even after a shingles rash goes away.

Shingles usually follows a pattern of development. It typically progresses with the following symptoms:

• First, you may notice a tingling or burning sensation in your skin.
• One to 5 days later (or concurrent with the initial pain) a rash appears as small red spots.
• Fluid-filled blisters develop a few days later.
• After 7 to 10 days, the lesions crust over.
• The rash disappears over the next 2 to 4 weeks.

In some cases, pain may persist for several months or even years after the rash has disappeared. This complication, known as postherpetic neuralgia (PHN), can be severe enough to affect your quality of life.

Certain antiseizure medications can help manage the pain. Gabapentin and pregabalin are two that are commonly used.

It’s unlikely to get shingles more than once — but it’s possible. That’s why it’s recommended to get the shingles vaccine at age 50 and older, even if you’ve already had the disease. Getting shingles three times is extremely rare.

Shingles occurs when the varicella-zoster virus is reactivated due to a weakened immune system. This can create a painful, blistering rash. The risk of getting shingles goes up with age, with increased likelihood after age 50.

Shingles often doesn’t require treatment to make it go away, but some antiviral medications can help you recover faster and reduce your risk for complications.

Shingles (Herpes zoster): causes, symptoms, diagnosis and treatment.

Herpes zoster is an infectious disease whose causative agent (herpesvirus type 3) also causes chicken pox.

Since the virus, penetrating into sensitive nerve endings, is integrated into the genetic apparatus of nerve cells, it is impossible to remove it from the body. In those who have had chickenpox, the virus goes into a latent (inactive) state.

When the immune system is weakened, the virus is activated, affecting the skin. The disease often develops in the elderly and in immunocompromised individuals.

Causes of disease

The virus is transmitted from a patient with chicken pox or herpes zoster by contact or airborne droplets. The person who becomes infected primarily (most often a child) gets chickenpox. Penetrating through the mucous membranes into the blood and lymph, the virus reaches the nerve cells, where it begins to multiply. After recovery, the virus remains in the body for life, often being in an inactive state. The awakening of the infection is associated with weakened immunity caused by hypothermia, long-term use of steroid hormones, immunosuppression (after transplantation), chemotherapy and radiation therapy, as well as a general decrease in immunity in patients with blood diseases, oncological and viral diseases. Shingles is very severe in HIV-infected patients.

Classification of herpes zoster

The clinical picture of herpes zoster consists of skin manifestations and neurological disorders. There are typical and atypical forms of the disease. With an atypical form, an erased course of the disease is possible, in which papules develop in the foci of hyperemia, which do not transform into vesicles.

In herpes zoster, the spread of the pathological process corresponds to a certain area of ​​the skin and does not cross the anatomical midline of the trunk. In most patients, the rash is preceded by a burning or itching sensation in a specific area of ​​the skin, as well as pain, which can be stabbing, throbbing, shooting, paroxysmal or constant. In a number of patients, the pain syndrome is accompanied by general systemic inflammatory manifestations: fever, malaise, myalgia, and headache.

Infection of the central nervous system and involvement of the meninges can produce meningeal, encephalic (symptoms suggest virus involvement of the brain and/or spinal cord and meninges), or mixed forms of herpes zoster. If the infection spreads along the optic nerve, ophthalmic herpes develops.

When a rash appears over the entire surface of the skin and on parenchymal organs (eg, liver, kidneys), a generalized form of herpes zoster develops. Another type of shingles is hemorrhagic. A characteristic feature is the bloody fluid inside the vesicles.

Symptoms of herpes zoster

The onset of the disease is accompanied by general intoxication, malaise and fever. Nausea and vomiting are possible. Lymph nodes are enlarged.

There are pronounced pains along the affected nerve, which can be permanent, but more often they are paroxysmal itchy in nature, intensifying at night.

As a rule, they are provoked by any irritants: touching the skin, cold, movement. Some patients complain of loss of sensation in certain areas of the skin, which may be combined with increased pain response. Sometimes the pain syndrome in the absence of skin rashes can resemble angina pectoris, myocardial infarction, renal colic, or pancreatitis. The period of neuralgia preceding the rash lasts up to 7 days. Then nodules appear on one side of the body, from which bubbles form with transparent contents, which gradually become cloudy. After 3-7 days, most of the bubbles dry up with the formation of yellow-brown crusts. When the bubbles are injured, bright red sores are exposed. After the sores heal, small scabs or scars remain on the skin.

Most often, rash and pain are noted in the region of the ribs, lower back and sacrum, less often along the branches of the trigeminal, facial and ear nerve and on the extremities.

In rare cases, the mucous membranes are affected.

Herpes zoster diagnostics

It is possible to make a diagnosis after examining and questioning the patient. The doctor pays attention to the nature of the rash (localized and unilateral), the type of vesicles and complaints of itchy burning pain. It is more difficult to identify the atypical form of herpes zoster. With an erased form, pain and other neurological symptoms may be absent. In case of neurogenic disorders before the appearance of rashes, the diagnosis can be made on the basis of the results of laboratory tests. In this case, a histological examination is used, and the virus is isolated in cell culture. The Zanck test helps to quickly confirm the herpetic nature of the rashes: giant multinucleated cells are found in the scraping of the material taken from the base of the vesicle. However, this test does not make it possible to determine the type of herpes. The methods of enzyme immunoassay and indirect immunofluorescent reaction are also used. Recently, the diagnosis of viral infections is carried out using the polymerase chain reaction (PCR).

Which doctors to contact

Depending on the primary symptoms, patients with herpes zoster may see different specialists. However, first of all, you should go to
therapist for examination and referrals for tests. If limited, localized skin rashes appear and there are no pain symptoms, it is necessary to contact a dermatologist for differential diagnosis of erysipelas (caused by bacteria), eczema, etc. In case of severe pain syndrome, movement disorders, consultation is necessary
neurologist. In case of damage to the eyes, pain when moving the eyeballs, an ophthalmologist’s consultation is required. The generalized form of herpes often requires hospitalization and the combined efforts of an immunologist, a neurologist, and a dermatologist.

Herpes zoster treatment

With any localization of rashes, antiviral agents are first prescribed (the drug, the frequency of administration and dosage are determined by the attending physician!).

Their action is especially effective in the first 72 hours from the onset of clinical manifestations.

In the presence of a strong pain syndrome, the doctor may recommend anti-inflammatory therapy. However, contraindications must be taken into account (for example, chronic diseases such as arterial hypertension, diabetes mellitus, erosive lesions of the intestine, peptic ulcer of the stomach and duodenum). If analgesics don’t work, your doctor may prescribe central analgesics (often prescription drugs) and nerve blocks. External (topical) treatment is necessary to eliminate inflammation and prevent infection of the skin by other agents (eg, bacteria). With erosive forms of herpes zoster, creams and ointments with antibacterial action are applied to the affected areas.

Your doctor may also recommend treatments to improve immunity, such as taking vitamins (particularly B vitamins).

Complications

When the vesicles open, a secondary infection (bacterial infection of the skin) is possible, which is accompanied by fever and general intoxication.

Typical complications of herpes zoster include neuritis, paresis and paralysis of sensory and motor nerves.

Postherpetic neuralgia is difficult to treat.

The ocular form of herpes can lead to keratitis (inflammation of the cornea), less often to iritis (inflammation of the iris) or glaucoma (increased intraocular pressure). In addition, the development of optic neuritis is possible, sometimes with its subsequent atrophy and blindness. With the defeat of the branch of the oculomotor nerve, ptosis develops (drooping of the upper eyelid). Sometimes patients complain of hearing loss, damage to the vestibular apparatus, in severe cases – paralysis and paresis of the oral cavity. In addition, patients may report tinnitus or increased sensitivity to sounds. Damage to the lumbosacral nerve nodes sometimes leads to urinary retention, constipation or diarrhea. In patients with significantly weakened immunity (with HIV infection, oncological diseases), herpes zoster often occurs in a generalized form and is complicated by meningitis, encephalitis, or meningoencephalitis.

Shingles prevention

Since shingles is caused by the same pathogen as varicella, prevention of the disease will be based on the same measures as with chickenpox.

To prevent the spread of infection, isolation of the patient is necessary, which lasts up to 5 days from the moment the last element of the rash appears.

Persons who have been in contact with a patient with chickenpox are observed for 21 days. Active (vaccination) and passive (immunoglobulin administration) immunization are used as emergency prophylaxis. Vaccination is carried out for children older than 12 months and adults with no contraindications in the first 72-96 hours after probable contact with a person with chickenpox or shingles. Passive immunization with anti-varicella immunoglobulin is indicated for people with low immunity who have contraindications to vaccinations, pregnant women, children under 12 months of age and newborns whose mothers fell ill with chicken pox within 5 days before the birth of the child. The introduction of immunoglobulin is also carried out within 72-96 hours after contact with a patient with chicken pox or herpes zoster.

What is herpes zoster?

Herpes zoster, also called herpes zoster, is an infectious disease caused by the varicella-zoster virus. This is the same virus that causes chickenpox. Herpes zoster occurs only in those individuals who have previously had chickenpox. When chickenpox passes, the varicella-zoster virus remains in the body as inactive. This means that you may not feel symptoms, but the virus is still present in the body. When the varicella-zoster virus becomes active again, it causes herpes zoster.

How is herpes zoster spread?

Herpes zoster can be spread by touching the blisters of an infected person. Disseminated herpes zoster can be spread through contact with liquid droplets from the nose and throat of an infected person. Droplets containing the virus are released into the air when an infected person coughs or sneezes. They are easy to inhale and become infected.

If you have had chickenpox before, your virus will not become active through contact with a person who has herpes zoster. However, if you haven’t had chickenpox, you can get it after being in contact with someone who has herpes zoster.
