TORONTO – Toronto Public Health says women who attended a prenatal nutrition class earlier this week have been exposed to chicken pox.

Toronto Public Health says it’s trying to contact women who attended the Canada Prenatal Nutrition Program class on Tuesday afternoon at York Community Services (1651 Keele Street).

Women who attended the class and have not had chicken pox, or are unsure whether they have had chicken pox, are being advised to contact their obstetrician or prenatal health care provider immediately.

Chicken pox poses a serious risk of complications to pregnant women, and can cause severe complications to the fetus.

Pregnant women whose immune status is not known should receive Varicella-zoster immune globulin within 96 hours of exposure.

Health officials say the treatment should be given as soon as possible, and may be effective as late as Saturday afternoon.
