Susceptibility to varicella-zoster virus among adults at high risk for exposure

The adult health care provider who is susceptible to varicella zoster virus (VZV) represents a risk to her or himself and to patients. Nineteen percent of employees at this Children's Hospital had no or uncertain prior experience with VZV, and of these, 28% were found to be VZV susceptible, representing 5% of the total population of 2,730 hospital employees. During the 12 months of study, six of the potential 135 to 137 VZV-susceptible individuals acquired varicella. VZV-susceptible health care providers should be aware of their potential to both acquire and transmit VZV.
