Shingles, or herpes zoster, is a painful viral infection caused by the varicella-zoster virus — the same virus responsible for chickenpox. After chickenpox, the virus stays dormant in nerve cells and can reactivate years later, often due to weakened immunity or stress, causing a blistering rash.

“People over 50, those with weakened immune systems, or under stress are most at risk.” Early symptoms include fever, chills, headache, and fatigue. Within days, itching, burning sensations, redness, and blisters appear, followed by pain that can range from mild to severe.

“Shingles is more than just a painful rash.” Complications may include post-herpetic neuralgia, bacterial infections, and in rare cases, nerve paralysis or virus spread to organs like the brain or lungs.

The Shingrix vaccine significantly reduces the risk of shingles and its complications. Antiviral medications such as acyclovir, famciclovir, or valacyclovir help speed recovery if taken within 72 hours. Pain relievers like ibuprofen or paracetamol can also alleviate discomfort.

While shingles itself isn’t contagious, the virus can spread to those who haven’t had chickenpox or the vaccine. “Keep the rash covered, wash hands often, and avoid contact with vulnerable individuals” to protect others.
