Pregnant woman may present with a fever, malaise, and a rash.
Diagnosis of FVS
Prenatal diagnosis is possible using ultrasound when findings such as limb deformity, microcephaly, hydrocephalus, soft-tissue calcification and fetal growth restriction can be detected. A time lag of at least 5 weeks after the primary infection is advised because ultrasound performed at 4 weeks has failed to detect the deformities.
Amniocentesis is not routinely advised because the risk of FVS is low, even when amniotic fluid is positive for VZV DNA.
