Shingles is a painful skin rash caused by the reactivation of the chickenpox virus. It can lead to serious complications like long-term nerve pain. The shingles vaccine is the best way to protect yourself. Learn what shingles is, who needs the vaccine, and where to get vaccinated before symptoms begin.
What is shingles disease?
Shingles, also known as herpes zoster, is a viral infection caused by the varicella-zoster virus, the same virus responsible for chickenpox. After a person recovers from chickenpox, the virus remains dormant in the nervous system and can reactivate later in life, leading to shingles, according to the CDC. The condition is characterized by a painful, blistering rash that typically appears on one side of the body or face. Other symptoms may include fever, headache, and fatigue. The rash usually resolves within a few weeks, but the pain can persist for months or even years, a condition known as postherpetic neuralgia.
Shingles is more common in older adults and individuals with weakened immune systems, although it can occur in anyone who has had chickenpox. Vaccination is an effective way to reduce the risk of developing shingles and its complications. Early treatment with antiviral medications can help alleviate symptoms and shorten the duration of the outbreak, making it important to seek medical attention promptly if shingles are suspected, according to the CDC.
