Herpes zoster

Other names: Shingles, Zoster

DEFINITION

Shingles is a viral infection caused by the varicella-zoster virus, the same virus responsible for Chickenpox. It manifests as a painful rash typically appearing as a single stripe of blisters on one side of the torso.

SYMPTOMS

• Pain, burning, numbness, or tingling
• Sensitivity to touch
• Red rash followed by fluid-filled blisters
• Itching
• Additional symptoms like fever, headache, light sensitivity, and fatigue may occur

CAUSES

Shingles is a result of the reactivation of the varicella-zoster virus that remains dormant in nerve tissue after a person has had Chickenpox. Factors like aging and weakened immune systems can trigger this reactivation.

RISK FACTORS

• Age over 50
• Weakened immune system (HIV/AIDS, Cancer)
• Cancer treatments or certain medications

COMPLICATIONS

• Postherpetic neuralgia
• Vision loss
• Neurological problems
• Skin infections

TREATMENTS

Antiviral drugs like Acyclovir, Valacyclovir, and Famciclovir can help speed up healing. Pain management medications and topical treatments may also be prescribed.

PREVENTION

Vaccines such as the Chickenpox vaccine for children and adults and the Shingles vaccine for individuals over 50 can help prevent Shingles or reduce its severity.
