Serology reagents intended to detect and/or identify antigens or serum antibody titers to varicella-zoster virus, a DNA virus of the genus Varicellavirus, family Herpesviridae. These viruses cause chickenpox (varicella), an infectious disease typically transmitted by direct contact or through the respiratory route and characterized by the appearance of vesicular lesions on the skin and mucous membranes. Activation of varicella-zoster virus from a previous chickenpox (varicella) infection is likely to cause herpes zoster (also called shingles), a self-limited infection that affects ganglia and their areas of innervation, producing severe neuralgic pain and vesicles on the skin.
