What Is The Disease Called Shingles

Im Pregnant And Have Had A Blood Test For Chickenpox What Do The Results Of This Test Show

Shingles: What you need to know about causes, symptoms, and prevention.

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.

Complications Of Shingles In The Eye

The shingles rash will fade after a few weeks, but the pain can continue for many more weeks or months. This complication is caused by nerve damage called postherpetic neuralgia, which is more common in older adults. In most people, the nerve pain will get better over time.

In the eye, swelling of the cornea may be severe enough to leave permanent scars. Shingles can also cause swelling of the retina. It can also increase eye pressure and lead to glaucoma. Glaucoma is a disease that damages the optic nerve. You can also develop an injury to the cornea.

Treating shingles in the eye right away can help you avoid long-term problems, including permanent vision loss.

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

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.

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.

Shingles: Signs, Symptoms, Cause, Treatment, Is It Contagious?

After having chickenpox, your body doesnt rid your system of the virus. Instead, the virus stays in a portion of the spinal nerve root called the dorsal root ganglion. In most people, the virus simply stays there quietly and doesnt cause problems. Scientists arent always sure why the virus gets active again, but they know stress can be a cause.

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.

Am I At Risk For Shingles

Everyone who has had chickenpox is at risk for developing shingles. Researchers do not fully understand what makes the virus become active and cause shingles. But some things make it more likely:

  • Older age. The risk of developing shingles increases as you age. About half of all shingles cases are in adults age 60 or older. The chance of getting shingles becomes much greater by age 70.
  • Trouble fighting infections. Your immune system is the part of your body that responds to infections. Age can affect your immune system. So can HIV, cancer, cancer treatments, too much sun, and organ transplant drugs. Even stress or a cold can weaken your immune system for a short time. These all can put you at risk for shingles.

Most people only have shingles one time. However, it is possible to have it more than once.

Preventing The Virus Spreading

If you have the shingles rash, do not share towels or flannels, go swimming, or play contact sports. This will help prevent the virus being passed on to someone who has not had chickenpox.

You should also avoid work or school if your rash is weeping and cannot be covered.

Chickenpox can be particularly dangerous for certain groups of people. If you have shingles, avoid:

  • women who are pregnant and have not had chickenpox before as they could catch it from you, which may harm their unborn baby
  • people who have a weak immune system, such as someone with HIV or AIDS
  • babies less than one month old, unless it is your own baby, in which case your baby should have antibodies to protect them from the virus

Once your blisters have dried and scabbed over, you are no longer contagious and will not need to avoid anyone.

Can You Get Shingles If You Havent Had Chickenpox

What is Shingles?

No. You cant get shingles if youve never had chickenpox, but you can get chickenpox from someone who has shingles. If youve never had chickenpox and you come into direct contact with the oozing, blister-like rash of someone with shingles, the varicella-zoster virus can infect you and you would develop chickenpox.

Once youve had chickenpox, you could develop shingles at some point in your life. This is because the varicella-zoster virus never fully goes away after youve had chickenpox. It lies quietly inactive in your nerve tissue. Later in life, the virus may become active again and appears as shingles.

Can you get chickenpox more than once?

Its rare to get chickenpox twice in your life. Once youve had chickenpox, youre usually immune to it for the rest of your life. However, its not totally impossible. If you have a severely weakened immune system , you can get chickenpox a second time. If youve had chickenpox, you are more likely to get shingles at some point in your life than a repeat bout of chickenpox.

Can You Get Shingles More Than Once

Although possible, its rare to experience shingles more than once. In a 2019 study , researchers found the reoccurrence rate of shingles was 5.3 percent over an average of a 4.4-year follow-up period.

The researchers found that experiencing shingles that lasted more than 30 days significantly increased the risk of reoccurrence. Other risk factors were:

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.

Are There Natural Ways To Boost Your Immune System To Help Lessen The Chances Of Developing Shingles

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.

When To Seek Medical Advice

Staving off shingles

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.

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 .

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.

Can You Still Develop Shingles If Youve Been Vaccinated For Chickenpox

Yes. Despite being vaccinated for chickenpox, you can still get shingles. No vaccine is 100% protective, and the effectiveness of vaccines lessens with time. However, people who get the chickenpox vaccine are significantly less likely to develop shingles later in life compared with people who never received the chickenpox vaccine. One recent 12-year study found that the number of shingles cases was 72% lower in children who had received the chickenpox vaccine compared with those who didnt.

What Are The Complications Of Shingles

Shingles: What You Should Know | Johns Hopkins Medicine

Symptoms of shingles usually dont last longer than 3 to 5 weeks. However, complications can happen. The main complications that can result from shingles include:

  • Postherpetic neuralgia . The most common complication of shingles is called postherpetic neuralgia . This continuous, chronic pain lasts even after the skin lesions have healed. The pain may be severe in the area where the blisters were present. The affected skin may be very sensitive to heat and cold. If you had severe pain during the active rash or have impaired senses, you are at increased risk for PHN. The elderly are also at greater risk. Early treatment of shingles may prevent PHN. Pain relievers and steroid treatment may be used to treat the pain and inflammation. Other treatments include antiviral drugs, antidepressants, anticonvulsants, and topical agents.
  • Bacterial infection. A bacterial infection of the skin where the rash happens is another complication. Rarely, infections can lead to more problems, such as tissue death and scarring. When an infection happens near or on the eyes, a corneal infection can happen. This can lead to temporary or permanent blindness.

How Is Shingles Spread

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 .

Key Points About Shingles

  • Shingles is a common viral infection of the nerves. It causes a painful rash or small blisters on an area of skin.
  • Shingles is caused when the chickenpox virus is reactivated.
  • It is more common in people with weakened immune systems, and in people over the age of 50.
  • Shingles starts with skin sensitivity, tingling, itching, and/or pain followed by rash that looks like small, red spots that turn into blisters.
  • The rash is typically affects just one area on one side of the body or face.
  • Treatment that is started as soon as possible helps reduce the severity of the disease.

Why Is The Shingles Vaccine Important

Shingles causes a painful rash and blisters and it can lead to serious complications. The most common complication is post-herpetic neuralgia , a condition that causes burning pain that can last long after the shingles rash and blisters go away. The older you are when you get shingles, the more likely you are to develop PHN.

Getting vaccinated is the best way to prevent shingles and PHN.

Shingles is caused by the same virus that causes chickenpox. After you have chickenpox, the chickenpox virus stays dormant in your body. The virus can activate years later and cause shingles.

Symptoms of shingles include:

Shingles cant spread from person to person like chickenpox. But if you have shingles, you can spread the virus to someone who isnt immune to chickenpox meaning someone who hasnt had chickenpox and isnt vaccinated against it. If that happened, the person might get chickenpox but not shingles. Learn more about shingles.

  • Adults age 50 and older
  • Adults 19 years and older who have a weakened immune system because of disease or treatments

You need to get 2 doses of Shingrix. Youll need the second dose 2 to 6 months after the first dose. You need to get Shingrix even if you:

  • Have already had shingles
  • Have been vaccinated against shingles with Zostavax
  • Are not sure if youve had chickenpox

Herpes zoster is more common in people with a depressed immune system and those over the age of 50. It’s quite rare in children and the symptoms are mild compared to what an adult may experience. Children most at risk for herpes zoster are those who had chicken pox during the first year of life or whose mothers had chicken pox very late during pregnancy.

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.

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.

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.
