| varicella zoster virus immunity in multinational health care workers of a saudi arabian hospital. | the health care worker (hcw) is vulnerable to hospital-acquired varicella zoster virus (vzv) infection, and thereafter may transmit infection to coworkers and patients who are susceptible and hospitalized. interventions to prevent varicella transmission in hcw groups of uncertain immunity prove labor intensive, costly, and disruptive. therefore, documentation of total varicella immunity in hcws is desirable. | 2003 | 14608306 |
