What should you know about chickenpox and shingles are caused by the same virus?

Varicella causes chickenpox, typically producing an itchy rash that can appear in crops across the body, along with fever or tiredness. After the illness, the virus can remain inactive in nerve tissue. Shingles occurs when it reactivates, often causing pain, tingling, or a localised blistering rash.

A person with shingles can pass varicella to someone who has not had protection, causing chickenpox rather than shingles in that person. Direct contact with blister fluid is a recognised route of spread, so covering the rash and careful hand hygiene are useful precautions.

Arrange a GP Consultation if a new blistering rash is painful, one-sided, widespread, or accompanied by fever. Tell the clinician when symptoms began and whether you have had chickenpox or vaccination. This helps distinguish a first infection from reactivation and supports timely treatment decisions.

Keep the affected skin clean and avoid picking blisters. Do not share towels or clothing, and limit close contact with pregnant people, newborns, and people with weakened immunity until the rash has been assessed. Antiviral Treatment may be discussed when clinically appropriate; do not use someone else’s medicine.

Seek urgent assessment for a rash near the eye or ear, facial weakness, severe headache, confusion, breathing difficulty, or rapidly worsening pain. Prompt advice is also needed for an older adult, a person with reduced immunity, or anyone who cannot maintain fluids. Call before attending if a contagious rash is possible.

Ask whether the pattern fits chickenpox, shingles, or another rash; whether antiviral treatment is useful; and how long you should avoid close contact. Ask about protecting household members, which symptoms need urgent review, and whether vaccination should be discussed after recovery.
