Shingles Virus FAQs Answered | Shingles Causes, Symptoms Treatment | Dr. Jen Caudle

The blood test can show that you:

  • Are immune and have no sign of recent infection. You have nothing further to be concerned about.
  • Are not immune and have not yet been infected. You should avoid anyone with chickenpox during your pregnancy.
  • Have or recently had an infection. You should discuss what the risks are for your stage of pregnancy with your healthcare provider.

Chickenpox Versus Shingleswhats The Difference

Did you know? The same virus that causes chickenpox also causes shingles. Although shingles and chickenpox are caused by the same virus, they are not the same illness. Chickenpox is usually a milder illness that affects children. Shingles results from a reactivation of the virus long after the chickenpox illness has disappeared.

The chickenpox virus stays in the body even after recovery. Later in life, the virus can reactivate and cause shingles. If you have shingles, you can spread the varicella virus to people who have never had chickenpox or never received the chickenpox vaccine. These people will develop chickenpox, not shingles. It takes from 10 to 21 days after exposure to chickenpox or shingles for someone to develop chickenpox.

What are the symptoms?

Chickenpox

  • Initial symptoms include sudden onset of fever, headache, and feeling tired.
  • An itchy blister-like rash, usually starting on the face, chest or back, follows 1-2 days later.
  • The rash then spreads to the rest of the body, and new blisters continue to appear for about 3-4 days.
  • Generally, within 1 week, the blisters dry out and scabs form and fall off.

Shingles

How contagious is it?

Shingles Shingles cannot be passed from one person to another. Someone with an infectious shingles rash can spread chickenpox if the other person has never had chickenpox. However, someone with shingles will not cause another person to develop shingles.

Is there a vaccine?

Which Shingles Vaccine Is Best

Eventually, your doctor will start mentioning the shingles vaccine which can help prevent shingles from developing, as well as reduce its severity if it does still develop. The shingles vaccine can also reduce your risk of postherpetic neuralgia, one of the most common complications of shingles.

“Because shingles becomes increasingly more common as a person ages, the shingles vaccine is currently recommended for people over the age of 50. There are two vaccine options, Shingrix and Zostavax, with Shingrix being the newer of the two vaccines and the preferred choice as it is more effective.”

When it comes to how the shingles vaccine works, Shingrix is a shot that requires two doses administered six months apart. There are temporary side of effects of this shingles vaccine that can be unpleasant, however. Shingles vaccine side effects typically don’t last more than three days, but include:

  • Redness or swelling

How To Avoid Spreading Shingles

The varicella-zoster virus is typically less likely to be transmitted with shingles than with chickenpox. However, the varicella-zoster virus can be passed on from the time that your symptoms start until your rash and blisters have crusted dry.

If you have shingles and are otherwise healthy, you can still go out in public or to work. But be sure to follow these tips:

  • Keep the shingles rash clean and covered. This can help prevent other people from coming into contact with your blisters.
  • Wash your hands often. Also, try not to touch the blisters.
  • Avoid being around pregnant people. The varicella-zoster virus can cause serious health risks for both pregnant people and their babies. Risks include pneumonia and permanent damage to the unborn child. If you find you have shingles after spending time with someone whos pregnant, let them know at once so they can ask their OB-GYN for advice. Be especially careful to avoid pregnant people who havent had chickenpox or the vaccine for it.
  • Avoid other at-risk people. Stay away from premature babies, infants with low birth weights, and children who havent yet had chickenpox or its vaccine. Also, avoid people with weakened immune systems. These include people living with HIV, organ transplant recipients, and people taking immunosuppressant medications or having chemotherapy.

Doctors recommend the chickenpox vaccine for children. Preventing chickenpox will also prevent shingles.

Can You Get Chickenpox If You’ve Been Vaccinated

Yes. About 15% 20% of people who have received one dose of varicella vaccine do still get chickenpox if they are exposed, but their disease is usually mild. Vaccinated persons who get chickenpox generally have fewer than 50 spots or bumps, which may resemble bug bites more than typical, fluid-filled chickenpox blisters. In 2006, the Advisory Committee on Immunization Practices voted to recommend routine two-dose varicella vaccination for children. In one study, children who received two doses of varicella vaccine were three times less likely to get chickenpox than individuals who have had only one dose.

Is There A Vaccine For Shingles

There are two shingles vaccines currently available, Shingrix and Zostavax. Shingrix vaccine, a newer vaccine, is preferred over Zostavax for the prevention of shingles and its complications. Two doses of Shingrix given 2 to 6 months apart are recommended for healthy adults 50 years of age and older. Shingrix is also recommended for adults who have previously received Zostavax. A single dose of Zostavax may still be used to prevent shingles in certain cases for healthy adults 60 years and older.

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.

Shingles Vaccination What You Should Know:

The Centers for Disease Control and Prevention recommends shingles vaccine for people 60 years of age and older. This is a one-time vaccination to prevent shingles. There is no maximum age for getting the shingles vaccine.

Anyone 60 years of age or older should get the shingles vaccine, regardless of whether they recall having had chickenpox or not. Studies show that more than 99% of Americans ages 40 and older have had chickenpox, even if they dont remember getting the disease.

Your risk for getting shingles begins to rise around age 50. However, shingles vaccine is only recommended for persons age 60 and older because the safety and effectiveness of the vaccine have only been studied in this age group.

Even if you have had shingles, you can still receive the shingles vaccine to help prevent future occurrences of the disease. There is no specific time that you must wait after having shingles before receiving the shingles vaccine. The decision on when to get vaccinated should be made with your healthcare provider.

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.

Who Is At Risk For Getting Shingles

People who have had chickenpox who are more likely to develop shingles include those:

  • With a weakened immune system .
  • Over the age of 50.
  • Who have been ill.
  • Who have experienced trauma.
  • Who are under stress.

The chickenpox virus doesnt leave your body after you have chickenpox. Instead, the virus stays in a portion of your spinal nerve root called the dorsal root ganglion. For the majority of people, the virus stays there quietly and doesn’t cause problems. Researchers aren’t always sure why the virus gets reactivated, but this typically occurs at times of stress.

Shingles can transmit via coughing and sneezing only if blisters have developed in the persons oral cavity.

How Can You Prevent Shingles

Vaccination is the only way to reduce the chance of getting shingles since the virus that causes shingles is already present in anyone who has had chickenpox.

The Centers for Disease Control and Prevention recommends two doses of recombinant zoster vaccine to prevent shingles and related complications in adults 50 years and older. Shingrix is also recommended for adults 19 years and older who have weakened immune systems because of disease or treatments they are receiving. The varicella vaccine protects against chickenpox.

Mode Of Transmission Of Varicella Zoster Virus

Chickenpox transmission is mainly person-to-person by airborne respiratory droplets, but also occurs by direct contact with vesicle fluid of chickenpox cases or contact with the vesicle fluid of patients with herpes zoster. Immunosuppressed cases with disseminated herpes zoster may also transmit via respiratory droplets. Indirect contact occurs through articles freshly soiled by discharges from vesicles of infected persons. Scabs are not infective.

Experts sound alarm over shingles

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.

How You Catch The Varicella

Shingles is not contagious. You cant catch shingles from someone. However, a person with shingles can pass along VZV to people who have never contracted chickenpox.

VZV can be transmitted from a person with shingles to someone who has never had chickenpox via direct contact with fluid from shingles rash or blisters. Its not possible to pass along VZV before shingles blisters appear or after lesions crust over.

However, shingles is a lot less contagious than chickenpox. By covering up your rash, you can prevent the spread of the virus.

Shingles usually happens many years after an initial chickenpox infection. The first signs of a reactivation of the virus are malaise, fever, a localized tingling or burning sensation, and pain. Within a few days a one-sided rash forms on the face or body. It can takes up to 10 days for the rash and blisters to crust over. It will clear up entirely several weeks later.

Can You Get Shingles If Youve Never Had Chickenpox

You can only get shingles if youve previously had chickenpox. After a chickenpox infection, the virus stays in your nervous system. If the virus becomes reactive again, it leads to shingles. The first time youre infected with the virus it leads to chickenpox.

Vaccines are now widely available to protect against chickenpox and shingles. Getting vaccinated is the most effective way to prevent both before they develop.

How Is Shingles Diagnosed

The clinical appearance of shingles, with characteristic painful blisters localized to the region of a specific nerve on one side of the body, is usually sufficient to establish the diagnosis. No diagnostic tests are typically required. However, particularly in people with impaired immune function, shingles may sometimes not display the characteristic clinical pattern. In these cases, samples from the affected area may be tested in a laboratory, either by culturing the tissue or blister drainage for growth of the virus or by identifying the genetic material of the virus.

Who Should Avoid Contact With Shingles

Is shingles contagious?

One way of preventing the spread is to avoid contact with people who have shingles blisters.

If a person gets chickenpox, they usually only have it once. This is for shingles. A person is unlikely to have shingles more than once, unless they have a weakened immune system, which may result from a health issue or immunosuppressant treatments, such as chemotherapy or radiation therapy.

Anyone with shingles blisters should especially avoid contact with:

  • Pregnant people who have never had chickenpox or its vaccination: If chickenpox develops during pregnancy, especially 521 days before birth, it can be dangerous for the fetus.
  • Children who have not had chickenpox or its vaccination: Until a child is vaccinated, they should avoid contact with anyone who has chickenpox or shingles blisters.
  • People with weakened immune systems, such as:
  • infants born early or with a low birth weight
  • people with HIV, leukemia, lymphoma, or other health issues that have this immune effect
  • people who take immunosuppressant medications, such as chemotherapy
  • people who have had organ transplants

After contact with the varicella virus, a person in any of the above groups may be unable to ward off the infection. Their risk of developing chickenpox, then shingles and its complications may be higher.These groups are also likely to have the illnesses for longer, and the symptoms may be more severe.
