Shingles, also known as herpes zoster, is a viral infection caused by the reactivation of the varicella-zoster virus (VZV)—the same virus that causes chickenpox. It is characterised by a painful, blistering rash that usually appears on one side of the face or body. The rash typically forms a distinctive band or belt-like pattern around the torso, but it can also spread across multiple skin areas. While shingles is not contagious, the virus may spread through contact with active blisters, potentially causing chickenpox in those who are not previously infected or vaccinated.

What You'll Learn
Shingles rash
Shingles is a viral infection characterised by a painful, blistering rash. It is caused by the reactivation of the varicella-zoster virus, which is the same virus that causes chickenpox. The rash usually appears 2-3 days after the initial symptoms, which may include tiredness, headaches, photophobia, and tender and painful skin.
The rash typically manifests as a single strip or band of small, fluid-filled blisters, and it usually appears on one side of the body, often in a dermatomal distribution. The blisters are typically painful and itchy and may be accompanied by a tingling or burning sensation. In some cases, the rash may cross multiple dermatomes and take on a more widespread appearance, resembling chickenpox more than shingles.
The rash typically lasts for about 10 to 15 days, during which a scaly crust might appear. After the rash clears, the skin usually returns to normal, but there can be some scarring or secondary bacterial infection in severe cases. It is important to seek medical attention if you suspect you have shingles, as early intervention is key to successful treatment and preventing long-term complications.
Shingles can occur anywhere on the body but most commonly affects the chest and lumbar region. It often appears around the rib cage or waist and may look like a "belt" or "half belt". This characteristic pattern is due to the virus working down the nerves that branch out from the spinal cord. In some cases, shingles can also affect the eye area, known as ophthalmic shingles, which can lead to temporary or permanent vision loss.

Blisters
Shingles is a viral infection that causes a painful, blistering rash. It is characterised by a red, blistering rash that usually appears on one side of the face or body. Tiredness, headaches, photophobia, and tender and painful skin may occur 2 to 3 days before the skin turns red and breaks out in tiny fluid-filled blisters.
These blisters are similar to those caused by chickenpox and may be accompanied by itching. They usually appear on the face and torso but can occur elsewhere. In most cases, the blisters appear over a localised area, but widespread blistering is possible. In rare cases, there may be no rash at all.
Shingles blisters can sometimes erupt and ooze. They may then turn slightly yellow and begin to flatten. As they dry out, scabs form. During this stage, the pain may ease a little, but it can continue for months or, in some cases, years. Once all blisters have completely crusted over, the risk of transmitting the virus is low.
Shingles often appears around the rib cage or waist and may look like a “belt” or “half belt,” sometimes called a “shingles band.” The rash usually lasts about 10 to 15 days. During that time, a scaly crust might appear. Once the attack is over, the skin usually returns to normal, but there can be some scarring or a secondary bacterial infection in severe cases.

Post-herpetic neuralgia
Shingles, or herpes zoster, is a viral infection caused by the reactivation of the varicella-zoster virus (VZV)—the same virus responsible for chickenpox. It presents as a painful, blistering rash that usually appears on one side of the face or body. While shingles is not contagious, the virus may spread through contact with active blisters, potentially causing chickenpox in those who are not immune.
Shingles can lead to serious complications, including post-herpetic neuralgia (PHN), a condition caused by damage to nerve fibres. PHN is characterised by persistent pain that lasts for longer than three months after the shingles rash has cleared. The pain is often described as burning, sharp, stabbing, or deep and aching. It typically affects the area of skin where the shingles outbreak occurred, most commonly the chest and abdomen, and usually on one side of the body. However, PHN can occur anywhere, including the face and head.
The risk factors for developing PHN include advancing age, with older individuals being more susceptible, and a weakened immune system. People with diabetes or Aboriginal and Torres Strait Islander people aged 50 and over are also at an increased risk. Prior vaccination can reduce the likelihood of developing PHN, but antiviral medications have not shown the same effect.
To manage the symptoms of PHN, pain-relieving medications or tablets specific to nerve pain may be prescribed. While there is a slow resolution of the pain syndrome over time, a small group of patients may experience chronic pain that does not respond to medical treatment.

Vaccination
Shingles, or herpes zoster, is caused by the reactivation of the varicella-zoster virus (VZV) in someone who has previously had chickenpox. It is characterised by a painful rash of fluid-filled blisters on one side of the face or body, often in a band-like pattern. The risk of developing shingles increases with age, particularly after 50 years, and it affects around 1 in 3 people during their lifetime.
The Australian Immunisation Handbook provides specific recommendations for shingles vaccination. It is suggested for people aged 50 and over who live with someone with a weakened immune system. Additionally, it is recommended for Aboriginal and Torres Strait Islander people aged 50 and over due to their increased risk of hospitalisation from shingles compared to non-Indigenous people.
While vaccination does not guarantee that an individual will not develop shingles, it significantly reduces the risk and severity of the illness, thereby decreasing the likelihood of long-term complications. Mild side effects may occur after vaccination, but serious reactions are rare.
It is important to consult with a healthcare professional to determine eligibility for the shingles vaccine and discuss any concerns regarding side effects.

Diagnosis
Shingles is a viral infection caused by the reactivation of the varicella-zoster virus (VZV), which is responsible for chickenpox. It causes a painful, blistering rash that usually appears on one side of the face or body. The rash typically lasts about 10 to 15 days and can leave some scarring in severe cases.
To confirm a diagnosis of shingles, a doctor may perform additional tests. These can include taking a viral skin swab to identify the DNA of the varicella-zoster virus and distinguish it from other viral infections. A blood test may also be used to detect the presence of herpes zoster IgM and IgG antibodies. These tests help differentiate between herpes zoster (shingles) and herpes simplex, as well as confirm the presence of the virus.
It is important to seek medical attention promptly if you experience any symptoms of shingles, especially during pregnancy or if you are over 50 years old, as the risk of complications increases with age. Early diagnosis and treatment are crucial for effective management of shingles.
In Australia, shingles is a nationally notifiable disease monitored through the National Notifiable Diseases Surveillance System (NNDSS). The Australian government provides free shingles vaccinations for eligible individuals under the National Immunisation Program.
