Shingles (Herpes Zoster): Pathophysiology, Risk Factors, Phases of Infection, Symptoms, Treatment

Q: Is herpes zoster contagious?A: Herpes zoster itself is not contagious – this means that someone with shingles cannot give shingles to someone with whom they come into contact. However, it is possible for someone with shingles to pass on the varicella virus through contact with fluid from the rash blisters. If the person who contracts the virus is not vaccinated, they may then contract the virus and develop chickenpox.

Q: How long is someone with shingles contagious for?A: The person with shingles is contagious until the rash develops crusts.

Q: Can children get shingles?A: Yes: anyone who has had chickenpox can develop shingles, including children. However, this is rare. Shingles is much more common among older adults than it is among children or young adults.

Q: What can someone with shingles do to avoid passing on the varicella virus to others?A: Someone who has shingles should keep their hands clean, avoid scratching the rash and keep the rash covered, if possible. The shingles virus is not spread through coughing or sneezing, but it can be spread through direct contact with the rash.

Q: Who should avoid contact with someone who has an active shingles rash?A: People who are at particular risk of shingles, and who should therefore avoid someone with shingles, include:

Q: Can you get shingles more than once?A: In most cases, a person only has shingles once. However, some people have shingles two or three times in their lifetime.

Ocular Manifestations Of Herpes Zoster Ophthalmicus

The skin manifestations of herpes zoster ophthalmicus strictly obey the midline with involvement of one or more branches of the ophthalmic division of the trigeminal nerve, namely the supraorbital, lacrimal, and nasociliary branches . Because the nasociliary branch innervates the globe, the most serious ocular involvement develops if this branch is affected. Classically, involvement of the tip of the nose has been thought to be a clinical predictor of ocular involvement. Although patients with a positive Hutchinsonâs sign have twice the incidence of ocular involvement, one third of patients without the sign develop ocular manifestations.8 A summary of ocular findings in patients with herpes zoster ophthalmicus is presented in Table 1.

Lancinating, dysesthetic, or other pain develops in the involved site, typically followed within 2 to 3 days by a rash, usually crops of vesicles on an erythematous base. The site is usually one or more adjacent dermatomes in the thoracic or lumbar region, although a few satellite lesions may also appear. Lesions are typically unilateral and do not cross the midline of the body. The site is usually hyperesthetic, and pain may be severe. Lesions usually continue to form for about 3 to 5 days.

Herpes zoster may disseminate to other regions of the skin and to visceral organs, especially in immunocompromised patients.

Shingles can often be diagnosed by your doctor based upon the distinctive appearance and distribution of the characteristic shingles rash. A painful, blistering rash that is localized to defined dermatomes is a sign highly suggestive of shingles. Blood work or other testing is usually not necessary. Diagnosing shingles before the appearance of the rash or in cases of zoster sine herpete can be challenging. In cases where the diagnosis is unclear, laboratory tests are available to help confirm the diagnosis. Depending on the clinical situation, testing can be done using either blood work or by specialized testing of skin lesion samples.

What If You Have Shingles Around Or In Your Eye

Community Eye Health

If shingles are in the eye, they most often show up inside the eyelid and on the surface or the eyeball, says Rebecca Taylor, MD, an ophthalmologist with Nashville Vision Associates in Tennessee.

On the surface, says Dr. Taylor, they mainly show up on the cornea, which is the clear dome of tissue that covers your iris , and the conjunctiva the clear tissue that covers the whites of your eye and the inside of your eyelid.

If shingles is in these places, she says, youll be prescribed eye drops with steroids to calm the lesions, and lubricating tears for comfort.

If you have had shingles in your eye, says Taylor, your eye doctor will monitor you for 3 to 12 months to make sure that your eye is returning to health and that no new developments have occurred. You may also be encouraged to have a yearly eye exam until otherwise instructed by your eye doctor.

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.

Treatment Of Herpes Zoster Ophthalmicus

  • Antiviral drugs taken by mouth

  • Corticosteroid eye drops

  • Eye drops to keep the pupil dilated

As with shingles anywhere in the body, early treatment with an antiviral drug such as acyclovir, valacyclovir, or famciclovir can reduce the duration of the painful rash. When herpes zoster infects the face and threatens the eye, treatment with an antiviral drug reduces the risk of eye complications.

Corticosteroids, usually in eye drops, may also be needed if the eye is inflamed.

Eye drops, such as cyclopentolate or atropine, are used to keep the pupil dilated, to help prevent a severe form of glaucoma, and to relieve pain.

If youve ever had the chickenpox, there is a chance you may develop shingles. Shingles is a painful rash caused by the reactivation of the chickenpox virus. This rash will break out across one side of the body with a burning or tingling sensation. It may also cause flu-like symptoms. There are more 200,000 cases in the United States each year. If you develop shingles, it is possible for the rash to appear on your face, and can even get into your eyes.

If shingles develops on your face, pay close attention to your eyes. Shingles in the eyes can create serious vision problems. The ocular surface can become swollen and inflamed, causing pain and blurry vision. Corneal ulcers can also develop and may lead to permanent scarring. The virus may even damage the corneal nerves causing chronic problems with ocular healing.

If youve never had chickenpox, talk with your healthcare provider about getting the chickenpox vaccine.

Is A Vaccine Available To Prevent Shingles

Two vaccines are available in the United States to reduce your chance of developing shingles and postherpetic neuralgia. One vaccine, Zostavax®, has been available since 2006. The second vaccine, Shingrix®, has been available since 2017. Shingrix is recommended as the preferred vaccine by the Advisory Committee on Immunization Practices, a group of medical and public health experts.

Shingrix® is given as a two-dose shot in the upper arm. You should receive the second dose two to six months after receiving the first. Shingrix has been shown to be more than 90% effective in preventing shingles and postherpetic neuralgia. Its effectiveness remains above 85% for at least four years after receiving the vaccine.

Due to high levels of demand for the Shingrix vaccine and a supply shortage, the vaccine manufacturer is managing the timing and distribution of the vaccine throughout the United States. It plans to continue to manage the availability of the vaccine and hopes to make available the same or increased number of doses and to shorten the wait time for delivery this year .

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.

Disseminated Herpes Zoster Infection in an HIV Patient

After having chickenpox, your body does not 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.

If I Get The Shingles Vaccine Does This Mean Im 100% Protected From Getting Shingles

No, just like most vaccines, getting vaccinated doesnt provide 100% protection from disease. However, getting the shingles vaccine reduces your risk of developing shingles. Even if you do develop shingles, youll be more likely to have a mild case. Also, youll be much less likely to develop postherpetic neuralgia, the painful condition that can follow a shingles outbreak.

How Contagious Is Shingles

Shingles is not contagious, but the varicella-zoster virus that causes it can be spread to another person who hasnât had chickenpox, and they could develop the disease. You canât get shingles from someone with shingles, but you can get chickenpox.

The varicella-zoster virus is spread when someone comes into contact with an oozing blister. Itâs not contagious if the blisters are covered or have formed scabs.

To prevent spreading the varicella-zoster virus if you have shingles, be sure to keep the rash clean and covered. Do not touch the blisters, and make sure to wash your hands often.

You should avoid being around at-risk people, such as pregnant people and people who have weak immune systems.

for adults ages 50 and older.

Zostavax is a live vaccine, which contains a weakened form of the varicella-zoster virus. The CDC recommends the newer Shingrix vaccine because itâs over 90 percent effective and is more likely to last longer than the Zostavax vaccine.

While side effects such as allergic reactions are possible from these vaccines, the CDC has no documented cases of the varicella-zoster virus being transmitted from people who were vaccinated.

Are There Alternative Treatments

Some studies show that various alternative treatments, from acupuncture to supplements, can offer relief. The research isnât complete, but some shows promise. Check with your doctor before you try any of these:

TENS . This therapy uses tiny electrical pulses to relieve pain. A TENS unit is about the size of a smartphone and comes with small patches called electrodes. You put them over the painful area and turn the unit on and off as your pain comes and goes.

Traditional Chinese medicine: These treatments aim to restore balance in your body. They include acupuncture, the ancient practice of inserting very thin needles into your skin at specific points. Also, moxibustion and cupping, two types of heat therapy, are supposed to draw out toxins. These treatments may be done in combination.

Creams and other skin treatments: A mixture of liquid dimethyl sulfoxide and idoxuridine, an antiviral drug, may reduce swelling and the number of blisters you have when you put it on your rash. And chlorophyll, the chemical that gives plants their green color, is also used directly on the rash as a cream or saline solution.

Supplements: Youâll find a long list of herbs, pills, and oils that claim to relieve shingles. Most have no research to back them up, but there are a couple of exceptions. Papain, a protein found in papayas, is sold in capsules. And manuka and clover honeys can be put directly on your skin. Very early studies on both show they may be helpful.
