With localized herpes zoster, the rash usually appears as a wide strip on one side of the body. With disseminated (more widespread) herpes zoster, the rash covers a wider area of the body.
Shingles' clinical manifestations are divided into 3 distinct phases: preeruptive, acute eruptive, and chronic. The preeruptive phase (or preherpetic neuralgia stage) usually lasts about 48 hours but can stretch to 10 days in some cases.
In general, as long as the lesion can be covered, a person with shingles does not need to stay home from work or school. Health care workers and others working with high-risk individuals should remain home from work until the blisters have scabbed over.
The differential diagnosis for HZ includes herpes simplex virus, impetigo, candidiasis, contact dermatitis, insect bites, autoimmune blistering disease, dermatitis herpetiformis, and drug eruptions.
