Diagnostic Considerations

Diagnostic considerations in cases of suspected chickenpox include viral exanthems, pityriasis lichenoides et varioliformis acuta, disseminated herpes simplex virus infection, atypical herpes zoster, rickettsial disease, and neonatal syphilis.

All of the differential diagnoses listed are active considerations, with the exception of smallpox, which would be a concern in the event of biologic warfare.
