New Variant of Varicella-Zoster Virus

摘要

In 1998, a varicella-zoster virus glycoprotein E (gE) mutant virus(VZV-MSP) was isolated from a child with chickenpox. VZV-MSP, representing a second VZV serotype, was considered ararity. We isolated another VZV-MSP-like virus from an elderlyman with herpes zoster. These gE mutant viruses may havearisen through independent mutation or may represent a distinctVZV subpopulation that emerged more than 50 years ago
