Chickenpox and Shingles

Most children, particularly those under the age of 10, catch chickenpox thanks to the fact that the virus that causes it is highly infectious.

Most children - particularly those under the age of 10 - catch chickenpox thanks to the fact that the virus that causes it is highly infectious. This explains why more than 90 percent of adults are immune to chickenpox, because if you get it once, you become immune to the virus.

But after a child has chickenpox, the virus - called varicella-zoster - travels up a nerve root near the spine and stays there, lying dormant. And in later life it can reactivate, causing a condition called shingles. Shingles is quite common, as according to the NHS one in four people will have at least one episode during their life.


Itchy rash

Both chickenpox and shingles cause a rash that turn into itchy blisters. With chickenpox, the rash can cover a child's body - though some children have a mild attack with just a few spots. Other symptoms are similar to those of flu, such as a high temperature, aches and pains and nausea. If you catch chickenpox as an adult, these flu-like symptoms can be worse than if you'd had it as a child (in fact, the older you are getting chickenpox, the worse your symptoms tend to be).

The shingles rash, on the other hand, most commonly affects one side of the body, usually the upper body - though you can also get it on your head and neck, and even your eyes. But while the chickenpox rash is just very itchy, the shingles rash also causes a dull or burning pain - which can be severe in some people - and you may experience tingling and numbness too. Like chickenpox, shingles can cause flu-like symptoms such as headache and a high temperature.
 

How long do they last?

The chickenpox rash gets very itchy very quickly (after about 12 hours), then the blisters start to dry out and form scabs after a day or two. For the first three to five days, new spots may appear, so a child with chickenpox will typically have some spots crusting over and some filled with fluid. The scabs should start falling off after one or two weeks, when the rash should gradually disappear. Some marks may be left by the scabs, but in younger children the scabs don't leave behind any scarring (teenagers and adults, however, may be left with some chickenpox scars).

Shingles, on the other hand, can last longer, with a typical episode dying down after two to four weeks. During the first week new blisters may keep appearing, but after a few days they dry out and crust over.

Some people can develop a condition called post-herpetic neuralgia (PHN) after having shingles, particularly those who are elderly or have a weakened immune system (PHN is thought to affect up to one in five people over the age of 50 who've had shingles). The most common complication of shingles, PHN can cause severe nerve pain and itching long after the rash has disappeared, lasting for months or even years (in some cases, says the NHS, PHN can be permanent).

Chickenpox rarely causes serious complications, but a very small number of children go on to develop encephalitis (infection of the brain) or meningitis. Babies less than four weeks old are most at risk of developing chickenpox complications, as are pregnant women and those with a weakened immune system.


Chickenpox treatments

While having chickenpox can make you feel unwell and irritable, the virus usually clears up without any treatment. You can, however, take paracetamol - an over-the-counter painkiller - if you have a high temperature or if you're in pain. If you're caring for a child with chickenpox, make sure to give them the correct dose of paracetamol for their age (always read the dosage instructions).

You should, however, avoid treating the symptoms of chickenpox with ibuprofen, which is also an over-the-counter painkiller. That's because there's a small risk of ibuprofen and other non-steroidal anti-inflammatory drugs (NSAIDs) causing skin reactions with chickenpox.

If you're having problems sleeping because the rash is making you itch, you may be able to take an over-the-counter antihistamine in tablet or liquid form that acts as a mild sedative (these aren't suitable for children under a year old). Applying calamine lotion or a cooling gel may also help soothe itching skin.


Pregnancy warning

If you catch chickenpox while you're pregnant, the virus can cause severe symptoms and may also cause complications for your unborn baby. Only three in every 1,000 women catch chickenpox during pregnancy in the UK, says the NHS.

But if you do catch the virus during pregnancy, you may have to take an antiviral medicine or have immunoglobulin treatment - which is given by injection - to stop your symptoms getting worse (see your GP immediately if you're pregnant and think you may have chickenpox).

Some adults with chickenpox may also need antiviral medicine to prevent their symptoms becoming severe (these medicines, however, are usually only effective if taken early on in the course of the infection).


Stop the virus spreading

Meanwhile if you or your child has chickenpox, it's important to stay away from women who may be pregnant as well as newborn babies and anyone with a weakened immune system. Public Health England recommends that children with chickenpox are kept home from school for five days, while adults should stay off work until all their blisters have turned to scabs (this is when the virus is no longer infectious).

It's also a good idea to keep objects and surfaces free from the virus by cleaning them with a sterilising solution to stop the virus spreading to other members of your household. Also wash any bedding and clothes that may be infected with the virus.


Should you see your GP?

Most cases of chickenpox clear up by themselves so you shouldn't usually have to see a doctor. But there are a few instances when you should see your GP straight away, including the following:

  • If the skin around the blisters becomes red and painful.

  • If you develop breathing difficulties or chest pain.

  • If you become drowsy or feel very weak.

  • If your rash bruises or bleeds into the skin.

  • If you have pain or a headache that gets worse despite taking paracetamol.


Treatments for shingles

Like chickenpox, there's no cure for shingles. But if you think you have shingles, you should see your GP straight away, as you may need a prescription painkiller such as codeine. Some people, however, may only need to take paracetamol, which is available without a prescription.

Some people with shingles - usually people aged 50 and older and those with a weakened immune system - may also be prescribed a course of antiviral tablets. And the reason it's important to your doctor as soon as possible is that antiviral medicines - which can make your symptoms milder as well as reduce how long they last - are most effective if you take them within 72 hours of the rash appearing.

If you have severe pain with the shingles virus, your GP may suggest you take a type of antidepressant medicine or an epilepsy medication, both of which are also used to treat nerve pain. Medical moisturisers called emollients - which you can buy over the counter - may also help if your rash is itchy, or you could try applying calamine lotion to the affected area.
 

Is it contagious?

While you can't get shingles from someone with the virus, you can catch chickenpox from them if you haven't already had it. This explains why it's important to avoid contact with other people who may not have had chickenpox - especially pregnant women and those with an immune system problem - until you're no longer contagious (since the virus is passed on by the blisters, once they dry up you're not contagious any more). If you can cover up your blisters with clothing, your risk of infecting others is small.


Should you get the jab?

Currently, if you're aged between 70 and 78, you're eligible for a vaccine to prevent shingles on the NHS. This is a single injection (unlike the flu jab, which you need to have every year), and can help prevent the reactivation of the shingles virus or make your symptoms milder and last for a shorter length of time if you do get it.
 
According to the NHS, shingles is fatal for around one person in every 1,000 aged 70 and older - rare complications include pneumonia, hepatitis, encephalitis and meningitis - while for many others it can be very painful and uncomfortable. But even if you've already had shingles, you can still get the vaccine, as some people get the virus more than once. You don't have to do anything, as your GP will invite you to have the vaccine when you're eligible.


Self care for chickenpox and shingles

If you or someone you're caring for has chickenpox or shingles, there are a few things you can do to make yourself or them more comfortable:

Six chickenpox dos and don'ts:

  • Do drink lots of fluids, especially water, to prevent dehydration.

  • Don't wrap yourself up if your room has a normal temperature - instead stay cool and wear loose-fitting clothes, preferably made of cotton.

  • Do apply a cooling gel or lotion - such as calamine lotion - to soothe your skin

  • Don't try to cool a child's skin with a cold sponge - this can actually make their temperature worse.

  • Do keep fingernails clean and short to prevent scratching and possible scarring.

  • Don't use a fan directly on a child to keep them cool - but do use a fan on the other side of the room to keep the air circulating or open a window.


Six shingles dos and don'ts:

  • Do keep your rash clean and dry to prevent it becoming infected.

  • Do use non-sticky dressings to cover your blisters to prevent the virus spreading to others (this may also reduce pain caused when your rash comes into contact with your clothes).

  • Don't wear clothing that makes you too hot - choose something loose and cool (tight clothing may irritate your rash and make it more inflamed).

  • Do use a cool compress or take a cool bath to soothe your skin, or apply calamine lotion to relieve itching.

  • Don't share things like towels and flannels with anyone else while you have a rash (wash anything that comes into contact with your skin on the hottest possible temperature setting on your washing machine).


Natural relief for chickenpox and shingles

If your skin is itching, aloe vera gel may be an ideal alternative to calamine lotion. Another way to soothe your skin naturally is to take an oat bath. Put a handful of oats in a muslin bag (or take a square of muslin or similar material, place a handful of oats in the middle and tie the corners together) and either drop the bag/cloth in your bath water or secure it beneath the tap, so that the water runs through it (oats are thought to contain anti-inflammatory compounds that ease skin irritation).

There are also a few nutritional supplements you could try, including the following:


High-strength multivitamin and mineral

If you have shingles or post-herpetic neuralgia, a high-potency multivitamin and mineral supplement may help protect against cell damage. Look for a supplement with all the key ingredients, including vitamins C, E and selenium for antioxidant support.


Lysine

You may also like to support your skin by taking a lysine supplement. Lysine (also called L-lysine) is one of the eight essential amino acids, and is thought to play an important role in the immune system. It's important for the body's production of collagen, a protein that's essential for healthy skin. Some natural health practitioners also believe taking a lysine supplement may reduce the pain of shingles as well as speed up recovery.


B complex

A good-quality vitamin B complex supplement that includes vitamin B12 may help support the production of myelin, which is essential for the formation of the myelin sheath (a protective fatty layer that covers the spinal, cranial and peripheral nerves). Vitamin B12 deficiency is known to cause myelin sheath damage, which may lead to neurological problems.

The virus that causes shingles is thought to lay dormant in nerve pathways as well as in myelin sheaths and cells. Some natural health practitioners believe that keeping the myelin sheath healthy may even make the reactivation of the virus - which causes the symptoms of shingles - less likely.

There's also a older study that suggests vitamin B12 as a treatment for post-herpetic neuralgia (i).
