Accuracy of prenatal ultrasound screening to identify fetuses infected by cytomegalovirus who will develop severe long-term sequelae.

Routine ultrasound screening in pregnancy is not an appropriate screening tool for congenital CMV infection leading to long-term sequelae, contrasting with the high performance of targeted prenatal imaging in known cases of fetal infections. Non-specific nature of ultrasound features and their evolution and lack of awareness of caregivers about cCMV are the main explanations. Sonologists' awareness and knowledge of maternal serological status in the first trimester seem key to the performance of routine prenatal ultrasound. This article is protected by copyright.
