Shingles (Herpes Zoster)
Shingles, also known as Herpes Zoster, is a viral infection caused by the Varicella Zoster Virus (VZV) — the same virus responsible for chickenpox. After a person recovers from chickenpox during childhood, the virus does not completely leave the body. Instead, it remains dormant in the nerve ganglia and may reactivate later in life as shingles.
Reactivation commonly occurs when the immune system becomes weakened, particularly in older adults or individuals with underlying medical conditions.
Symptoms of Shingles
Shingles typically begins with:
- Burning pain, tingling, or itching along a nerve pathway
- Followed by a red rash that develops into clusters of fluid-filled blisters arranged along the affected nerve (commonly on the torso, face, or arms)
- Some patients may experience fever, fatigue, and skin sensitivity, even with light touch
The rash usually dries and forms scabs within 2–4 weeks.
A common complication is Postherpetic Neuralgia (PHN) — persistent nerve pain that continues after the rash has healed. This condition is more frequently seen in older adults and can significantly affect quality of life.
High-Risk Groups
Individuals at higher risk include:
- Adults aged 50 years and older
- Those who previously had chickenpox
- People with weakened immune systems, such as cancer patients or individuals taking immunosuppressive medications
- Individuals experiencing chronic stress or inadequate rest
Shingles Vaccination
Vaccination is an effective way to reduce the risk of developing shingles and to lessen the severity of symptoms if the disease occurs.
Shingrix is currently the most recommended shingles vaccine due to its high effectiveness and strong safety profile, including for individuals with weakened immune systems.
Key information:
- People who have previously had shingles can still receive the vaccine to help prevent recurrence
- Vaccination is recommended even for individuals who do not recall having chickenpox, as many people were exposed unknowingly
- Common side effects may include arm soreness, redness or swelling at the injection site, mild fever, and body aches
Conclusion
Although shingles may appear to be a mild condition, it can cause significant discomfort and long-term complications, especially in older adults. Prevention through vaccination with Shingrix is therefore a valuable and effective option for protecting long-term health and maintaining quality of life.
