Probable Case: An acute illness with maculo-papulovesicular rash and lack of epidemiologic link to another confirmed or probable case or lack of laboratory confirmation.

Breakthrough Case: Vaccinated cases that are milder, less contagious, have lower fever and fewer lesions (<50). Lesions are often maculopapular instead of vesicular. Atypical appearance often leads to misdiagnosis. Consider laboratory confirmation given atypical appearance.

Breakthrough Case
Breakthrough varicella is defined as a case of varicella due to infection with wild-type VZV occurring more than 42 days after varicella vaccination.

Herpes Zoster Virus (Shingles):
Characterized by vesicular lesions in one dermatome. Many labs automatically report + VZV PCRs to the health department. Talk to your lab about filtering out shingles results so they are not reported to CDPH.
Shingles is not a reportable disease
