A 25-day-old infant developed varicella 22 days after her mother received varicella vaccine postpartum. Infection with vaccine-strain varicella-zoster virus was confirmed by genetic analysis. The mother had no postvaccination rash nor did other contacts have rash or recent vaccination. The potential means of transmission to the infant are explored.

    ABSTRACT: SUMMARY Varicella-zoster virus (VZV) was once thought to be a fairly innocuous pathogen. That view is no longer tenable. The morbidity and mortality due to the primary and secondary diseases that VZV causes, varicella and herpes zoster (HZ), are significant. Fortunately, modern advances, including an available vaccine to prevent varicella, a therapeutic vaccine to diminish the incidence and ameliorate sequelae of HZ, effective antiviral drugs, a better understanding of VZV pathogenesis, and advances in diagnostic virology have made it possible to control VZV in the United States. Occult forms of VZV-induced disease have been recognized, including zoster sine herpete and enteric zoster, which have expanded the field. Future progress should include development of more effective vaccines to prevent HZ and a more complete understanding of the consequences of VZV latency in the enteric nervous system.
