Shingles, or herpes zoster, is a viral infection caused by the reactivation of the varicella-zoster virus, the same virus responsible for causing chickenpox. Adults are at risk for shingles if they have experienced chickenpox before, this is because the virus stays in their bodies and is dormant in the nervous system. The virus reactivates when the immune system is weakened, leading to a painful rash appearing on the skin.
You cannot catch shingles from another person as it is not contagious. However, if you have never gotten chickenpox, you can contract the virus through direct contact with the fluid from a shingles rash.
Symptoms of Shingles
Symptoms of shingles can differ, but it usually starts with pain or a scorching feeling on one face or side of the body. These are some of the most common symptoms:
Rash | Rash is the main symptom of shingles which progresses into itchy blisters. It usually appears as a single stripe on the side of the face or body. |
Pain | Many people feel pain, tingling, or itching in the affected area. This pain, particularly felt in older adults, can be very serious. |
Other symptoms | Some patients may have a fever, headache, and fatigue. |
Reactivation of the Varicella-Zoster Virus
After a person recovers from chickenpox, the varicella-zoster virus stays dormant in the body. This virus can be reactivated at any point– usually during adulthood or old age, particularly when the immune system weakens due to ageing, illness, or using specific medications.
Complications of Shingles
Shingles usually heal naturally within several weeks. However, shingles can lead to severe complications if left untreated, particularly in older adults.
Postherpetic Neuralgia (PHN) | Postherpetic neuralgia is one of the most common complications. It is a condition in which the painful spot affected by shingles goes on for months, sometimes even years after the rash has healed. |
Skin infection | Bacteria can infect shingles if it is not treated properly, which can deteriorate the condition that requires the use of antibiotics. |
Vision problems | If left untreated, shingles that appear around the eyes can damage the optic nerve and may even cause blindness. |
Preventing Shingles
Preventing shingles mainly involves enhancing the immune response against the varicella-zoster virus (VZV) and reducing the likelihood of reactivation.
Vaccination | Vaccines for shingles are available and recommended for adults aged 50 years and older to help decrease the risk of getting shingles and the stage of illness if someone gets infected. |
Strengthening the immune system | You can strengthen your immune system and prevent viral reactivation by keeping up a healthy way of living, such as consuming healthy foods, getting sufficient rest, and reducing your stress levels. |
Avoid close contact | Avoiding close contact with those who have active chickenpox or shingles is recommended. |
