Infection from a common virus, cytomegalovirus (CMV), is the leading cause of non-genetic hearing loss in US newborns. ENT specialist Dr. Albert Park explains what can happen when infants are exposed to CMV while in the womb and steps that pregnant women can take to avoid infection Background: The burden of congenital cytomegalovirus (CMV)-associated sensorineural hearing loss (SNHL) in populations with CMV seroprevalence approaching 100% is unknown. The purpose of this. At 13 months of age, her hearing was reevaluated by an otolaryngologist and her vision by ophthalmologist. At that time, the patient was diagnosed with bilateral severe sensorial hearing loss, sensorial nystagmus, esotropia, and cortical visual impairment. She was given prescription glasses to facilitate amblyopia treatment. Discussion

Cumulative data suggest that CMV infection causes at least one-third of sensorineural hearing loss in young children. 45-47 Thus, universal neonatal screening for hearing loss will miss the significant proportion of CMV-associated hearing loss that develops over time and, as such, newborn hearing screening cannot completely detect all. CMV and Hearing LossCMV and Hearing Loss Sensorineural hearing loss (SNHL) occurs in 10-15% of children overall according to systematic review (Dollard et al., 2007) 11% of children without symptoms at birth 35% of children with symptoms at birth • Many losses are progressive or late-onse We know that CMV does not cause hearing loss if someone gets it after they are born. Because of this, to find out if CMV is a possible cause of a baby's hearing loss it is important to test blood that was taken very soon after the baby was born to see if CMV was present in these early days

Cytomegalovirus: A Major Cause of Hearing Loss in Children

Human cytomegalovirus (HCMV) is the primary cause of congenital infections.

So, the risk of hearing loss does not vary between primary and non-primary infections. Since non Introduction. Congenital Cytomegalovirus (CMV) is the most common viral pathogen encountered in newborns and the most prevalent congenital infection in human beings. It is a Herpes virus that has been documented to be linked to sensorineural hearing loss (SNHL) as it appears in 30-65% of children infected [1,2]

Introduction. Cytomegalovirus (CMV) is the leading nongenetic cause of congenital sensorineural hearing loss (SNHL) in developed countries. Reference Dahle, Fowler, Wright, Boppana, Britt and Pass 1, Reference Fowler, Dahle, Boppana and Pass 2 The prevalence of congenital CMV infection in our region of Austria is about 0.22 per cent. Reference Halwachs-Baumann, Genser, Danda, Engele, Rosegger. Although over 90 percent of infants infected with CMV are free of symptoms at birth, sensorineural hearing loss, chorioretinitis, mental retardation, and neurologic deficits subsequently develop.

There is an overall risk of approximately 15% that there will be some element of hearing loss caused by CMV in a congenitally infected baby. The total number of infants with neurodevelopmental injury, including hearing loss, caused by congenital CMV in the United States is estimated to be between 4,000-6,000 babies/year In one study (Naing et al, 2015) 18% of children born positive for CMV were without symptoms at birth, but later had a delayed onset of hearing loss. I would have liked to have seen a heightened level of suspicion that hearing loss may emerge with this child, because of his congenital CMV diagnosis Congenital CMV is the leading cause of nonhereditary sensorineural hearing loss (SNHL), and is a common cause of neurodevelopment disabilities, growth failure, and vision loss (Dollard et al., 2007).
