Varicella Zoster In Pregnancy

If a women who is pregnant is exposed to shingles or chickenpox, it is possible for her to acquire chicken pox if she is non-immune.  (there is then a risk of congenital varicella syndrome where there is segmental skin loss, limb hypoplasia, reduced birth weight)

If a pregnant lady is exposed to the virus then the first thing to do is measure IgG antibodies to VZV, if these are present then no further action needs to be taken and the woman can be relatively reassured.

If she is non-immune then she probably needs treatment with VZ immunoglobulin which has been shown to reduce severity and possible fetal infection.
