Shingles is an infectious disease caused by the varicella-zoster virus. This virus causes the illness known as chickenpox during childhood and stays dormant in the body. Shingles is a condition triggered by factors such as stress, a weakened immune system, and aging. As age advances, these factors can become activated, leading to the emergence of shingles. Symptoms of shingles include burning, itching, numbness, pain, and blisters. Treatment involves antiviral medications, pain relievers, and topical creams.
What is Shingles?
Shingles, also known as herpes zoster, is characterized by small blisters and painful skin rashes caused by the varicella-zoster virus, which affects the skin and nerves.
Shingles is caused by the same virus that leads to chickenpox. In individuals who have previously had chickenpox, this virus remains dormant in the sensory nerve cells known as dorsal root ganglia located in the spine.
Shingles, also known as herpes zoster, is the painful and blister-like skin rash that occurs when the varicella-zoster virus reactivates in the body. This condition affects the skin and nerves.
What are the Causes and Risk Factors of Shingles?
Shingles is a skin disease caused by an infection with the Varicella Zoster Virus (VZV). The same virus causes chickenpox during childhood. After chickenpox resolves, the virus remains dormant in the nerve roots. Years later, it can reactivate due to a weakened immune system and cause shingles.
Common risk factors playing a role in the emergence of shingles include:
-
Advanced age: Individuals over 50 have an increased risk
-
Weakened immune system: Conditions such as cancer treatment, HIV/AIDS, or organ transplantation can lead to shingles.
-
Stress and intense emotional pressure.
-
Chronic illnesses: Diabetes, heart diseases, and similar chronic conditions are considered risk factors for shingles.
-
Long-term use of medications: Prolonged use of corticosteroids or immunosuppressive drugs may trigger shingles.
What Are the Symptoms of Shingles?
Symptoms of shingles are seen in the areas where the infected nerves are located and appear unilaterally. Early symptoms include:
-
Tingling, burning, and sensitivity on the skin
-
Itching and stinging sensations
-
Local pain
A few days later, typical rashes begin to appear:
-
Fluid-filled blisters on the reddened skin
-
Blisters bursting and crusting over
-
Intense pain
In some cases, even after blisters heal, long-term nerve pain known as postherpetic neuralgia may develop and continue to show its effects.
How Does Shingles Progress?
Shingles typically appears on one side of the body and in a localized area. Common areas include:
-
Chest and back
-
Face and around the eyes
-
Waist and abdomen
How Long Does Shingles Last?
The duration of the disease varies from person to person, but generally lasts about 2 to 4 weeks from the onset of initial symptoms.
In some patients, especially older adults or those with weakened immune systems, nerve pain known as postherpetic neuralgia may persist for months or even years after the rashes have healed. Therefore, not only the rash phase but also the ongoing pain complaints affect the duration of the disease.
Early diagnosis and appropriate antiviral therapy can shorten the duration of the rashes and reduce the risk of developing long-term nerve pain.
Is Shingles Contagious?
Shingles can be contagious when there are active rashes. However, transmission occurs through direct contact. Someone who touches a person with shingles, who has not had chickenpox before, can contract a chickenpox infection. However, shingles is not directly transmitted person-to-person.
Modes of transmission include:
-
Contact with the fluid from open blisters
-
Sharing contaminated items
Therefore, it is important to adhere to hygiene rules during the active phase of the disease, keep the rashes covered, and avoid direct contact with others.
How is Shingles Treated?
Shingles treatment, when initiated early, yields the desired results. The primary goal of treatment is to prevent the virus from multiplying, alleviate pain, and prevent complications.
Antiviral Medications
-
Antiviral drugs like acyclovir, valacyclovir, and famciclovir limit the spread of the virus.
-
It is crucial to start treatment within the first 72 hours.
Pain Relief and Supportive Treatments
-
Pain relievers such as paracetamol and ibuprofen
-
Antidepressants or anticonvulsants to control nerve pain
-
Topical creams and cold compresses
Management of Complications
-
Special treatments are applied to reduce nerve pain if postherpetic neuralgia develops.
-
In cases of shingles around the eyes, follow-up with an ophthalmologist is necessary.
What Should Be Known About the Shingles Vaccine?
The shingles vaccine is an injection administered into the upper arm, and a single dose is sufficient. The primary aim of the shingles vaccine is to reduce the risk of shingles infection. Even while undergoing shingles, getting vaccinated can make symptoms milder and shorter. The shingles vaccine provides protection for at least five years.
Frequently Asked Questions
Can Shingles Fully Heal?
Yes, most cases fully resolve. However, some patients may develop a lasting nerve pain known as postherpetic neuralgia after the blisters have healed. Early treatment is quite effective in preventing this complication.
Can Shingles Recur?
Shingles usually occur once. However, there is a possibility of it occurring a second time in cases where the immune system is significantly weakened. Therefore, getting the shingles vaccine is important.
Is Shingles a Contagious Skin Disease?
Shingles is not transmitted directly from person to person. However, someone who has not had chickenpox before and comes into contact with the fluid from the rashes can contract chickenpox. Therefore, precautionary measures should be observed.
How Long Does Shingles Treatment Last?
The treatment duration generally lasts 2 to 4 weeks. However, nerve pain may last longer in some individuals. Early initiation of antiviral treatment can shorten the process.
Which Doctor Should I Consult for Shingles?
For shingles treatment, one can consult a dermatology specialist. If there is involvement in the eye area, consulting an ophthalmologist is beneficial, and in cases of severe pain, a neurologist may be consulted.
