Limitations
Other herpes viruses may cross react and produce high titers. Protection may be limited at low positive titers. Antibodies persist after infection has been treated or becomes dormant.
Clinical Significance
Varicella Zoster Virus (VZV) causes chickenpox and when reactivated, potentially decades later, causes shingles. Twenty percent of adults will develop shingles, a rash or blister of the skin that may cause severe pain.
