Varicella occurring in pregnancy can be dangerous for the fetus, the m
other, and the newborn. The fetus may experience multiple system damag
e. The mother and newborn are at increased risk for varicella pneumoni
a with a 9% and 20% fatality rate, respectively. The recent introducti
on of the varicella vaccine will affect the occurrence of gestational
infection. Toxoplasmosis is rarely dangerous for the pregnant woman, y
et the fetus and newborn may be at risk for chorioretinitis, hydroceph
alus, intracranial calcifications, and convulsions. The greatest chall
enge in the management of toxoplasmosis in pregnancy is diagnosis of t
he asymptomatic newborn before damage occurs. Strategies to prevent to
xoplasmosis should be taught to every pregnant woman as part of routin
e prenatal care.
