Can you get shingles more than once?

Yes, although uncommon, shingles can recur. Vaccination with Shingrix significantly reduces the risk of recurrence even if you have had shingles before.

Is shingles contagious?

Shingles itself is not contagious, but the varicella-zoster virus can spread to someone who has never had chickenpox, causing them to develop chickenpox rather than shingles.

What is postherpetic neuralgia?

Postherpetic neuralgia is a common complication where pain continues in the area of the rash for months or even years after the blisters have healed. It occurs more frequently in older adults.

Shingles

Also known as: Herpes zoster

Shingles is a viral infection caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. It produces a painful, blistering rash that typically appears as a stripe of blisters on one side of the body or face. Shingles is most common in older adults and people with weakened immune systems, and vaccination can significantly reduce the risk.

Symptoms

Pain, burning, or tingling sensation on one side of the body

Red rash that appears a few days after the pain

Fluid-filled blisters that break open and crust over

Itching at the rash site

Fever and chills

Headache

Fatigue

Sensitivity to touch in the affected area

Causes

Reactivation of the dormant varicella-zoster virus in nerve tissue
Weakened immune system allowing viral reactivation
Age-related decline in immune function

Risk Factors

Age over 50 years
Previous chickenpox infection
Immunosuppressive medications or conditions
Chronic stress or illness
Cancer treatments such as chemotherapy or radiation

Diagnosis

Clinical examination of the characteristic rash pattern
PCR testing of blister fluid or skin scrapings
Direct fluorescent antibody testing
Viral culture in atypical cases

Treatment

Antiviral medications such as acyclovir, valacyclovir, or famciclovir started within 72 hours
Pain relief with over-the-counter or prescription analgesics
Topical capsaicin or lidocaine patches for postherpetic neuralgia
Corticosteroids to reduce inflammation in some cases
Cool compresses to soothe blisters

Prevention

Shingrix vaccine recommended for adults 50 and older
Vaccination for immunocompromised adults as advised by their doctor
Avoiding contact with people who have not had chickenpox while blisters are active
