# Screening for Congenital Cytomegalovirus Infection in Newborns

## TL;DR

This paper discusses the underrecognized issue of congenital cytomegalovirus infection in newborns and reviews current screening and diagnostic approaches.

## Contribution

The study provides an updated overview of the epidemiology, clinical features, and diagnostic methods for congenital cytomegalovirus infection.

## Key findings

- Congenital cytomegalovirus affects about 1 in 200 live births globally.
- Most infected infants show no visible symptoms at birth, leading to underdiagnosis.
- Current screening and diagnostic approaches are reviewed to improve detection and awareness.

## Abstract

Congenital cytomegalovirus infection is an underrecognized congenital infection. Globally, it impacts approximately 1 of every 200 live births. Although infected infants can have an increased risk of long-term sequelae, such as neurodevelopmental impairments and sensorineural hearing loss, most of the infected infants do not show visible signs at birth. As congenital cytomegalovirus infection often goes undetected and screening programs are not widely accepted, awareness of congenital cytomegalovirus in neonates is lacking. The aim of this study is to offer the current status of the epidemiology, clinical manifestations, and laboratory testing for the diagnosis of congenital cytomegalovirus infection and newborn screening approaches.
