A 24-question survey on varicella-zoster screening programs and control mea
sures for varicella-zoster infections was sent to 170 Canadian healthcare f
acilities. The results indicated that 60% of Canadian healthcare facilities
have well-established preemployment varicella-zoster screening programs fo
r healthcare workers. Overall, 30% of healthcare facilities impose work res
trictions for susceptible healthcare workers, 49% use negative-pressure roo
ms for varicella-zoster management, and 28% have a policy to discharge susc
eptible exposed patients. Large variations exist among Canadian healthcare
facilities in their varicella-zoster infection control policies.
