What Is Herpes Zoster Virus

How Is Shingles Spread

Varicella zoster virus: Chicken Pox and Shingles (herpes zoster)

A person must have already had chickenpox in the past to develop shingles. A person cannot get shingles from a person that has shingles. However, the virus that causes chickenpox and shingles can be spread from a person with active shingles to a person who has never had chickenpox or had the chickenpox vaccine. The person exposed to the virus would develop chickenpox, not shingles. A person with shingles can spread the virus when the rash is in the blister-phase. The blister fluid is filled with virus particles. The virus is spread through direct contact with the rash or through breathing in virus particles that get mixed in the air. Once the rash has developed crusts, the person is no longer contagious. A person is not infectious before blisters appear or if pain persists after the rash is gone .

How Is Postherpetic Neuralgia Treated

Treatments include lotions or creams and/or other medications not specifically used for pain, such as antidepressants or drugs for epilepsy. Regular pain relievers are not usually effective for this type of pain.

If pain doesnt lessen, other treatments such as nerve blocks or steroid injections near the area where the nerves exit the spine can be tried. Implantable nerve stimulator devices are an option for severe, ongoing pain that has not responded to other treatments.

How Do You Get Shingles

Shingles usually occurs from inside your own body when the chickenpox virus reactivates. If you have not had chickenpox, you cant get shingles.

If you have not had chickenpox, you can be infected with chickenpox from someone who has shingles. This happens if you come in contact with the fluid from shingles blisters.

What Are The Complications Associated With Shingles

Shingles is not usually dangerous to healthy individuals although it can cause great misery during an attack. Anyone with shingles on the upper half of their face, no matter how mild, should seek medical care at once because of the risk of damage to the eye. Very rarely, shingles can lead to pneumonia, hearing problems, blindness, brain inflammation or death. For about one person in five, severe pain can continue even after the rash clears up. This pain is called post-herpetic neuralgia. As people get older, they are more likely to develop post-herpetic neuralgia, and it is more likely to be severe.

Complications Of Herpes Zoster Infection

Herpes Zoster

Shingles can cause complications if it affects the eye and the ear. It can also cause long-lasting pain even after the rash has gone.

Good to know: People who are older than 60 years of age are particularly vulnerable to complications of shingles and should visit a doctor as soon as they develop symptoms.

Rarely, shingles can lead to complications such as pneumonia, encephalitis or a secondary bacterial infection of the skin.

How Is Ramsay Hunt Syndrome Diagnosed

Your healthcare provider will perform a physical exam to diagnose Ramsay Hunt syndrome. Theyll ask you about your medical history and symptoms. Your provider will look for a rash and signs of weakness in your face.

Diagnosis can be difficult because the symptoms of the condition dont always develop at the same time. Therefore, your provider may request a laboratory test to confirm the diagnosis. They may collect a sample of your saliva, blood or fluid from a blister. A pathologist will examine the sample under a microscope, looking for the varicella-zoster virus.

It isnt necessary, but your provider may also request an imaging test called a magnetic resonance imaging scan. This test can give your provider proof that another condition or disorder isnt causing your symptoms.

Who Should Get The Shingles Vaccine

At this time, Shingrix is recommended for healthy adults who are 50 years of age or older. Individuals should receive the vaccine whether or not they recall having had chickenpox, as data shows that more than 99% of Americans over 40 years of age have had chickenpox, even if they do not remember having had it. Shingrix is also recommended for individuals who have already received the Zostavax vaccine, as Shingrix has demonstrated superior efficacy and longer-lasting protection.

Shingrix is not indicated for the prevention of primary varicella infection. The CDC recommends the varicella vaccine for healthy people who do not have evidence of immunity to varicella, including children, adolescents, and adults.

How Common Is Herpes Meningitis

Because herpes meningitis often resolves on its own, not all cases are recorded, so it’s unclear exactly how common it is. For some perspective, older data show that tens of thousands of meningitis-related hospitalizations in the United States are due to a virus like a herpes virus. Experts believe most cases of herpes meningitis are caused by HSV-2, which is present in roughly 12% of U.S. adults under age 50.

Transporting Storing And Handling Vaccines

Transport according to National vaccine storage guidelines: Strive for 5.60 Store at +2°C to +8°C. Do not freeze. Protect from light.

Zostavax must be reconstituted. Add the entire contents of the diluent container to the vial and shake until the powder completely dissolves. Reconstitute immediately after taking the vaccine out of the refrigerator. Use the reconstituted vaccine within 30 minutes.

Who Does Ramsay Hunt Syndrome Affect

Ramsay Hunt syndrome can affect anyone whos had chickenpox or shingles. Most cases occur in people age 60 and older. The condition rarely affects children but has been diagnosed as young as three years old. People who are immunocompromised are more likely to be affected and generally experience more severe symptoms. Theyre also less likely to have a complete recovery.

Ramsay Hunt syndrome treatment may include various medications. Your healthcare provider may prescribe:

Natural treatment for Ramsay Hunt syndrome includes using a cold compress to reduce your pain. You may also consider wearing an eye patch. If youre unable to close your eye, you risk damaging your cornea due to irritation. You may also want to use artificial tears or eye lubricants to prevent your eye from drying out.

If you have complete facial paralysis, your healthcare provider may perform a surgical procedure. The surgery can help relieve the pressure on your facial nerves.

Is Chickenpox Dangerous? Yes. Varicella

The symptoms may be more severe in newborns, persons with weakened immune systems, and adults. Serious problems can occur and may include pneumonia , brain infection , and kidney problems. Many people are not aware that before a vaccine was available, approximately 10,600 persons were hospitalized, and 100 to 150 died, as a result of chickenpox in the U.S. every year.

What Is The Recovery Time For Ramsay Hunt Syndrome

Ramsay Hunt syndrome recovery time depends on the severity of your facial paralysis. If you dont have much damage to your nerve and youre otherwise healthy, your symptoms may improve within a few weeks to a few months. However, it may take up to a year to achieve a full recovery. If the damage to your facial nerve is more severe, your chances of a full recovery are less likely.

Antiviral medications can help, but your chances of a full recovery are better if you start treatment within three days of symptoms appearing. Early diagnosis and prompt treatment with antiviral therapy seem to improve long-term outcomes. About 70% of people with Ramsay Hunt syndrome will return to complete or almost complete facial function. However, even with prompt treatment, some cases result in permanent facial paralysis or hearing loss.

Can Shingles Be Prevented

There are vaccines to prevent shingles or lessen its effects. The Centers for Disease Control and Prevention recommends that healthy adults 50 years and older get the Shingrix vaccine. You need two doses of the vaccine, given 2 to 6 months apart. Another vaccine, Zostavax, may be used in certain cases.

What Is The Prognosis Of Shingles

Generally speaking, shingles typically resolves within two to four weeks in most individuals. The prognosis is excellent for younger and healthy individuals who develop shingles, with very few experiencing any complications. However, in older individuals and in those with compromised immune systems, the prognosis is more guarded, as complications and more severe outbreaks of shingles occur more commonly in these groups.

Approximately 1%-4% of people who develop shingles require hospitalization for complications, and about 30% of those hospitalized have impaired immune systems. In the U.S., it is estimated that there are approximately 96 deaths per year directly related to the varicella-zoster virus, the vast majority of which occur in the elderly and in those who are immunocompromised.

There is no cure for shingles but there are treatments for managing the symptoms. Antiviral medications may ease the discomfort and reduce the duration of the symptoms, particularly if started within 72 hours of the first sign of shingles. Over-the-counter pain medications such as acetaminophen or non-steroidal anti-inflammatory drugs such as ibuprofen can be effective in relieving mild pain. Antibacterial agents can be given to treat bacterial infections of the shingles rash .

What Is Herpes Zoster

Herpes zoster, or shingles, is a common viral infection of the nerves, which results in a painful rash of small blisters on a strip of skin anywhere on the body. Even after the rash is gone, the pain may continue for months.

  • Shingles is relatively rare in children.
  • Your child is most at risk if he had chickenpox during the first year of life or if you had chickenpox very late during pregnancy.
  • A rash most often occurs on the trunk and buttocks, and usually goes away in one to two weeks.
  • Medication may help alleviate some of the pain, but the disease has to run its course.

How Does The Herpes Zoster Virus Spread

The herpes zoster virus that is shed from shingles lesions is highly contagious and can be spread through direct contact with the fluid caused by rash blisters.

Shingles have not been known to spread during intercourse or via sexual contact, although touching open sores will lead to a high risk of contracting the virus.

The herpes zoster virus has been detected in the saliva and nasal secretions of the affected individuals. So theoretically, the virus can be spread through kissing, although this is very rare.

Treatment Of Herpes Zoster Infection

Herpes zoster infection is usually treated with antiviral medication in people who are immunocompetent. These drugs helps shorten the duration and lessen the severity of shingles by easing the associated pain and promoting healing of the blisters. Medication should be taken as soon as possible after the rash appears.

Drugs often prescribed include:

  • Acyclovir. Taken orally, acyclovir has been the traditional antiviral for use in shingles treatment. However, other drugs have been developed which can be taken less frequently and are better absorbed by the body.
  • Famciclovir. Taken orally, famciclovir converts to the compound penciclovir which is effective against the varicella zoster virus.
  • Valacyclovir. Taken orally, valacyclovir treats pain and itching and helps sores to heal while preventing new sores forming.

Common side-effects of these drugs can include:

  • Headache
  • Tiredness
  • Painful menstruation

Some doctors may prescribe steroid tablets to reduce swelling and itching, but this is not recommended in most cases. Anti-inflammatory medications, such as ibuprofen, or other analgesics, may also help to reduce the pain and swelling.

People with shingles should try to avoid scratching at the rash. Calamine lotion and wet compresses can help soothe the itching.

Use In People With A History Of Herpes Zoster

varicella zoster virus

People with a history of herpes zoster were excluded from the Shingles Prevention Study , so there are no data on vaccine efficacy in this group.

One small clinical trial studied the safety and immunogenicity of Zostavax in people with a history of herpes zoster. Zostavax was well tolerated and immunogenic.59

When To Seek Medical Advice

Shingles is not usually serious, but you should see your GP as soon as possible if you recognise the symptoms. Early treatment may help reduce the severity of your symptoms and the risk of developing complications.

You should also see your GP if you are pregnant or have a weakened immune system and you think you have been exposed to someone with chickenpox or shingles and haven’t had chickenpox before.

Prevention Of Herpes Zoster

A recombinant zoster vaccine is recommended for immunocompetent adults ⥠50 years whether they have had herpes zoster or been given the older, live-attenuated vaccine or not 2 doses of the recombinant zoster vaccine are given 2 to 6 months apart and at least 2 months after the live-attenuated vaccine . The older, live-attenuated vaccine is no longer available in the US, but remains available in many other nations. The newer, recombinant vaccine appears to provide much better and longer-lasting protection than the older, single-dose, live-attenuated zoster vaccine . In a large clinical trial, the recombinant zoster vaccine was 90 to 97% effective at preventing herpes zoster. For immunocompetent adults ⥠60 years, the recombinant vaccine or the live-attenuated vaccine is recommended, but the recombinant vaccine is preferred. A postmarketing observational study observed an increased risk of during the 42 days following vaccination with the recombinant zoster vaccine. Data regarding the efficacy of the recombinant vaccine in immunocompromised patients are emerging, and there are currently no recommendations for its use in immunocompromised patients. The live-attenuated vaccine is contraindicated in immunocompromised patients.

Causes Of Herpes Zoster Infection

People at risk of developing shingles are those who have had chickenpox in the past. Herpes zoster infection occurs years, often decades, after a person has been infected with the varicella zoster virus that causes chickenpox.

The virus remains dormant in the body in the ganglia of the sensory cranial nerves and spinal dorsal root . If a personââ¬â¢s immunity to varicella zoster weakens over time, either due to age or if a person is immunosuppressed, the virus can reactivate. This reactivation is called herpes zoster infection, or shingles.

Conditions and situations that can suppress the immune system and make someone more at risk of developing shingles include:

  • Having the spleen removed ââ¬â for example, due to damage from injury or infection
  • Hypogammaglobulinemia, a condition where the body does not make enough antibodies

Yes, make sure all your vaccines are up to date, especially if you are planning a pregnancy. Vaccination is the best way to protect yourself and those you love. If you are not immune, you should be vaccinated. You will receive two doses of varicella vaccine one month apart. You should avoid becoming pregnant for at least one month after the last vaccination. Varicella vaccine should not be given to pregnant women. If you are pregnant, have your healthcare provider give you the varicella vaccine after your baby is delivered.

How Do People Get Shingles

People get shingles when the virus that causes chicken pox, varicella zoster, is reactivated in their body. The varicella zoster virus doesn’t leave the body, even after a person has recovered from chicken pox. It can flare up again, causing shingles, often many years after a person has had chicken pox. The virus tends to reactivate when a person’s immune system is weakened because of another health problem.

Herpes Zoster In People Who Received Varicella Vaccine

Although herpes zoster has always been uncommon among children, the rate of herpes zoster in U.S. children has been declining since the routine varicella vaccination program started. Varicella vaccine contains live attenuated VZV, which causes latent infection.

  • Children who have been vaccinated against varicella have lower rates of herpes zoster compared to children who had natural infection with varicella. The reason for this is that vaccinated children are less likely to become infected with wild-type VZV, and the risk of reactivation of vaccine-strain VZV appears lower compared with reactivation of wild-type VZV.
  • The number of older adults who have received varicella vaccine since it was licensed in 1995 is quite small. There is very little information on the risk of herpes zoster in people who got varicella vaccine as adults.

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