Can You Test For Shingles

Do You Need To Stay Away From Children People Who Are Pregnant Have Cancer Or Anyone With A Weak Immune System After You Get The Zostavax Vaccine

Shingles: Signs, Symptoms and Treatment with Dr. Mark Shalauta | San Diego Health

According to the CDC, its safe to be around babies and young children, pregnant women or anyone with a weakened immune system after you get the Zostavax vaccine. Even though the Zostavax vaccine contains a weakened live varicella-zoster virus, the CDC says theres no documented case of a person getting chickenpox from someone who has received the Zostavax vaccine. And remember: You cant get shingles unless youve already had chickenpox.

Is There Anything Else I Need To Know About Chickenpox And Shingles Tests

The Centers for Disease Control and Prevention recommends the chickenpox vaccine for children, teens, and adults who never had chickenpox or the chickenpox vaccine. Some schools require this vaccine for admittance. Check with your child’s school and your child’s health care provider for more information.

The CDC also recommends that healthy adults age 50 and older get two doses of the shingles vaccine called Shingrix, separated by 2 to 6 months. The vaccine provides strong protection against shingles and complications from the disease. You should get the vaccine even if youâve already had shingles, as it may prevent future outbreaks.

A different shingles vaccine called Zostavax is no longer available in the United States. If you had a Zostavax vaccine in the past, you should still get vaccinated with Shingrix. Talk to your health care provider about the best time get Shingrix.

Check If You Have Shingles

The first signs of shingles can be:

  • a tingling or painful feeling in an area of skin
  • a headache or feeling generally unwell

A rash will appear a few days later.

Usually you get the shingles rash on your chest and tummy, but it can appear anywhere on your body including on your face, eyes and genitals.

The rash appears as blotches on your skin, on 1 side of your body only. A rash on both the left and right of your body is unlikely to be shingles.

How Long Does A Shingles Outbreak Last

It can take three to five weeks from the time you begin to feel symptoms until the rash totally disappears.

  • First, a few days before the rash appears, you may feel pain in an area on your skin. The pain is described as itching, burning, stabbing or shooting. This usually happens before the rash comes.
  • Next, the raised rash appears as a band or a patch, usually on one side of your body. The rash usually appears around your waistline or on one side of your face, neck, or on the trunk , but not always. It can occur in other areas including your arms and legs.
  • Within three to four days, the rash develops into red, fluid-filled, painful, open blisters.
  • Usually, these blisters begin to dry out and crust over within about 10 days.
  • The scabs clear up about two to three weeks later.

    How Shingles Is Diagnosed

    You may need a chickenpox or shingles test if you are at risk for complications, are not immune to VZV, and/or have symptoms of infection. Symptoms of the two diseases are similar and include:

    • Red, blistering rash. Chickenpox rashes often appear all over the body and are usually very itchy. Shingles sometimes appear in just one area and are often painful.

    You may also need this test if you are in a high-risk group and were recently exposed to chickenpox or shingles. You can’t catch shingles from another person. But the shingles virus can be spread and cause chickenpox in someone who doesn’t have immunity.

    When Should I Get The Shingles Vaccine

    The current shingles vaccine is a safe, easy, and more effective way to prevent shingles than the previous vaccine. In fact, it is over 90% effective at preventing shingles. Most adults age 50 and older should get vaccinated with the shingles vaccine, which is given in two doses. You can get the shingles vaccine at your doctors office and at some pharmacies.

    You should get the shingles vaccine if you:

    • Have already had chickenpox, the chickenpox vaccine, or shingles
    • Received the prior shingles vaccine called Zostavax
    • Dont remember having had chickenpox

    Medicare Part D and private health insurance plans may cover some or all of the cost. Check with Medicare or your health plan to find out if it is covered.

    You should not get vaccinated if you:

    • Currently have shingles
    • Are sick or have a fever
    • Had an allergic reaction to a previous dose of the shingles vaccine

    If you are unsure about the above criteria or have other health concerns, talk with your doctor before getting the vaccine.

    What Are They Used For

    Health care providers can usually diagnose chickenpox or shingles with a visual examination. Tests are sometimes ordered to check for immunity to the varicella zoster virus . You have immunity if you’ve had chickenpox before or have had the chickenpox vaccine. If you have immunity it means you can’t get chickenpox, but you can still get shingles later in life.

    Tests may be done on people who don’t have or are unsure about immunity and are at higher risk of complications from VZV. These include:

    • Newborns, if the mother is infected
    • Teen and adults with symptoms of chickenpox
    • People with HIV/AIDS or another condition that weakens the immune system

    Can Shingles Be Prevented

    There are 2 vaccines available to reduce the likelihood of developing shingles, Zostavax and Shingrix. If you are over 50, you can talk to your doctor about whether you need it. It is recommended for everyone over 60 and is given free of charge in Australia to people aged 70 to 79.

    Vaccination will not guarantee that you will not get shingles, but it will reduce your chance of developing the condition. The vaccine used to protect against shingles is not the same as the vaccine used to protect against chickenpox. Read more about the chickenpox vaccine here.

    Why Does Shingles Appear Mostly On One Side Or In One Area Of Your Body

    The virus travels in specific nerves, so you will often see shingles occur in a band on one side of your body. This band corresponds to the area where the nerve transmits signals. The shingles rash stays somewhat localized to an area. It doesnt spread over your whole body. Your torso is a common area, as is your face.

    If You Have More Than One Area Of Blisters What Can You Expect If You Go To The Hospital

    Its important to note that most people with shingles dont need to be in a hospital, but if you do:

    • Youll be in a contact isolation room.
    • The door will be kept closed.
    • A sign on your door will remind people who have never had chickenpox or the vaccine not to enter.
    • The sign will also remind staff to wear gowns and gloves when entering the room.

    Is There A Connection

    Theres currently no evidence to clear up the question of whether having COVID-19 or getting vaccinated against the coronavirus that causes it increases your risk for developing shingles in any statistically significant way.

    But it seems clear that neither the virus nor the vaccines can cause a shingles outbreak since shingles is caused by a different virus entirely.

    To better understand the relationship between the two, lets look at some details about the herpes zoster virus and SARS-CoV-2, responsible for shingles and COVID-19, respectively, as well as what the research currently suggests about the link between the two conditions.

    Who Should Not Be Vaccinated With Shingrix

    You shouldnt receive the Shingrix vaccine if you:

    • Have ever had a severe allergy to this vaccine or any ingredient in this vaccine.
    • Are breastfeeding or pregnant.
    • Currently have shingles.
    • Are ill and have a high fever.
    • Have tested negative for immunity to varicella-zoster virus .

    Ask your healthcare provider if the benefits of getting the vaccine outweigh any potential risks.

    Is The Zostavax Vaccine Still Being Used

    Yes. The CDC, however, recommends Zostavax for adults age 60 and older, but not routinely for people aged 50 to 59. Zostavax is given as a single-dose shot versus the two-dose shot for Shingrix. Zostavax is less effective than Shingrix in preventing shingles and postherpetic neuralgia .

    You can consider Zostavax if you are allergic to Shingrix or if Shingrix is unavailable because of supply shortage and you want some immediate protection from a possible case of shingles and/or postherpetic neuralgia. Because its a weakened live vaccine, it may be dangerous if you have cancer, HIV, or take steroids, chemotherapy or other medications that suppress your immune system. Ask your healthcare provider if the Zostavax vaccine is an option for you.

    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 your pain doesnt lessen, you might try therapies like nerve blocks or steroid injections near the area where the nerves exit the spine. Your provider might suggest an implantable nerve stimulator device for severe, ongoing pain that hasnt responded to other treatments.

    Hows Shingles Without A Rash Diagnosed

    Shingles without a rash isnt common, but it may be more common than previously thought because it often goes undiagnosed. Shingles without a rash is difficult to diagnose based on your symptoms alone.

    Your doctor may test your blood, cerebrospinal fluid, or saliva to identify the presence of VZV antibodies. This will allow them to confirm a diagnosis of shingles without a rash. However, these tests are often inconclusive.

    Your medical history may provide clues that suggest you have shingles without a rash. Your doctor may ask if youve had a recent operation or if youre under increased stress.

    Once your doctor suspects you have VZV, theyll use antiviral medicines such as acyclovir to treat the shingles. They may also prescribe drugs for the pain.

    Other treatment will vary based on the location and severity of symptoms.

    Stress is a risk factor for developing shingles, so limiting your stress can be helpful. Try meditation, yoga or other relaxation methods.

    Other things you can do include:

    • Eat a healthy diet.
    • Aim for seven to nine hours of sleep each night.
    • Dont smoke or use tobacco products.

    These are all tips for an overall healthy lifestyle, not just for reducing your chance of getting shingles.

    How Is The Test Used

    Laboratory tests are not routinely used to diagnose active cases of chickenpox and shingles, which are caused by the varicella zoster virus . These conditions are usually diagnosed based upon a persons signs and symptoms. Most adults have been infected with VZV, and children are now vaccinated therefore, general population screening is not done. However, testing for VZV or for the antibodies produced in response to VZV infection may be performed in certain cases. For example, it may sometimes be performed in pregnant women, in newborns, in people prior to organ transplantation, and in those with HIV/AIDS. Testing may be used to:

    • Determine if someone has been previously exposed to VZV either through past infection or vaccination and has developed immunity to the disease
    • Distinguish between an active or prior infection
    • Determine whether someone with severe or atypical symptoms has an active VZV infection or has another condition with similar symptoms

    There are several methods of testing for VZV:

    Antibody testingWhen someone is exposed to VZV, the persons immune system responds by producing antibodies to the virus. Laboratory tests can detect and measure the level of two classes of VZV antibodies in the blood: IgM and IgG.

    Viral detectionViral detection involves finding VZV in a blood, fluid, or tissue sample. This can be done either by culturing the virus or by detecting the viruss genetic material .

    How Is Shingles Diagnosed

    Your healthcare provider will do a complete physical exam and ask about your medical history, specifically about whether you have ever had chickenpox.

    Your healthcare provider will likely know right away that it is shingles based on the unique rash. The rash usually appears one area on one side of the body or face. It appears as red spots, small fluid- or pus-filled vesicles, or scabs.

    The healthcare provider may also take skin scrapings for testing.

    Where Does Shingles Come From

    When you have chickenpox as a child, your body fights off the varicella-zoster virus and the physical signs of chickenpox fade away, but the virus always remains in your body. In adulthood, sometimes the virus becomes active again. This time, the varicella-zoster virus makes its second appearance in the form of shingles.

    What Should You Expect If You Get Shingles

    Shingles can be a very painful condition. If you think you have the symptoms of shingles, see your healthcare provider right away. Starting antiviral medications early can ease your discomfort and end symptoms earlier.

    A better approach to shingles is to take action and do what you can to lessen your risk of getting it. If you’ve never had shingles in the past, talk to your healthcare provider about getting the shingles vaccine. If youve never had chickenpox, talk with your healthcare provider about getting the chickenpox vaccine.

    What Problems Can Happen

    Most cases of shingles heal on their own, with or without treatment, and won’t lead to any other problems. In rare cases, shingles can lead to complications, including:

    • Ongoing pain : Damaged nerve fibers in the skin send confused messages to the brain, leading to pain. Pain can go on for a long time after the shingles rash is gone. This is the most common shingles complication.
    • Vision problems: Shingles near or in an eye can lead to vision loss.
    • Skin infections: A shingles rash can become infected with bacteria, leading to impetigo or cellulitis.
    • Nervous system problems: Shingles on the face can involve different nerves that connect to the brain. This can lead to nerve-related problems such as facial paralysis, hearing problems, and problems with balance. In very rare cases, shingles can lead to encephalitis .

    How Is Shingles Diagnosed And Treated

    If you think you might have shingles, talk to your doctor as soon as possible. Its important to see your doctor no later than three days after the rash starts. The doctor will confirm whether you have shingles and can make a treatment plan. Most cases can be diagnosed from a visual examination. If you have a condition that weakens the immune system, your doctor may order a shingles test. Although there is no cure for shingles, early treatment with antiviral medications can help the blisters clear up faster and limit severe pain. Shingles can often be treated at home.

    When Is It Ordered

    VZV antibody tests may be ordered when a health care practitioner wants to check whether a person has developed immunity to VZV, especially someone who is at high risk, such as an organ transplant recipient or a pregnant woman, and/or when a healthcare practitioner wants to identify a recent infection.

    VZV culture or DNA tests may be ordered when a person at risk, such as a newborn or immunocompromised person, has been exposed to VZV and is ill with atypical and/or severe symptoms to detect an active primary VZV infection in the baby or a primary or reactivated infection in the immunocompromised person.

    Shingles: What Are the Causes and Best Treatments?

    After the shingles rash has disappeared, you might continue to have nerve pain in that same area. Postherpetic neuralgia can last for months or years and become quite severe.

    More than 10% of people who get shingles develop postherpetic neuralgia. Researchers dont know why some people get postherpetic neuralgia and others dont. It may be that nerves become more sensitive or that the virus may be invading and damaging the central nervous system.

    Other complications include:

    • Other types of nerve issues like numbness or itching.
    • A bacterial infection of the shingles rash.
    • Eye and ear inflammation if the rash is near these organs.

    When To Get Tested

    When you have atypical and/or severe symptoms and your health care practitioner wants to distinguish between a VZV infection and another cause when a healthcare practitioner wants to check whether or not you are immune to VZV sometimes prior to an organ transplant or when a child, pregnant woman, or a person with a weakened immune system has been exposed to someone with chickenpox
