Let an agent explain herpes zoster in general terms, relay prevention, vaccination and treatment information from health authorities, describe complications that need urgent care, and route personal symptoms and treatment to clinicians.

Thing Registry Cross-cutting context

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain herpes zoster in general terms, relay prevention, vaccination and treatment information from health authorities, describe complications that need urgent care, and route personal symptoms and treatment to clinicians.

A painful rash caused by reactivation of the varicella zoster virus, which stays dormant in nerve ganglia after chickenpox; also called shingles, it appears as a band of blisters on one side of the body, may involve the eye or ear, can leave lasting nerve pain, and is preventable in older adults by vaccination.

What it is for: Not applicable; a disease.

It can be explain cause and course in general terms; relay vaccination recommendations; describe warning signs that need urgent care; route personal questions to clinicians.

Distinguishing features

Reactivation of varicella zoster virus

One-sided dermatomal rash

Risk rises with age and immune suppression

Postherpetic neuralgia as a lasting complication

What it looks like

A band of blisters on reddened skin on one side of the body, following a nerve, often with pain before the rash.

Physical character

lifetime risk: about one in three people - health authority estimates

rash duration: 2-4 weeks - typical

How it is recognised

One-sided band of blisters following a nerve

Pain, tingling or burning before the rash

Chickenpox is the first infection; herpes simplex is a different virus

  • How should vaccine schedules be linked by country?
  • The registry entry has merged aliases for specific presentations; should they be split off?
