Shingles, also known as herpes zoster, is a viral infection caused by the reactivation of the varicella-zoster virus (VZV), the same virus responsible for chickenpox. After a person recovers from chickenpox, the virus lies dormant in nerve cells and can reactivate years later, often triggered by factors like aging, stress, or a weakened immune system.
Shingles is characterized by a painful, blistering rash that typically appears on one side of the body or face. The rash is accompanied by itching, burning, or tingling sensations.
While shingles usually resolves within a few weeks, complications such as postherpetic neuralgia (chronic nerve pain), skin infections, and eye problems may occur, especially in older adults or those with weakened immune systems.
Vaccination can significantly reduce the risk of shingles and its complications, and is recommended for individuals aged 50 and older, as well as those 19 and older with weakened immune systems.
Early diagnosis and treatment are key to reducing symptoms and preventing complications. Treatment typically focuses on pain management and reducing the effects of the virus.
