They’re not always considered to be the culprit, but viruses are a common cause of both temporary and permanent hearing loss. For some viruses, like Cytomegalovirus (CMV) and Rubella (CRS), hearing loss is the most prevalent consequence, with CMV causing 40% of congenitally acquired sensorineural hearing loss and almost all patients with Congenital Rubella Syndrome suffering some degree of hearing loss. Both congenital (occurring in the womb) and acquired hearing loss (occurring from transmitted diseases outside of the womb) may occur as a result of a viral infection such as measles, the mumps, rubella, chickenpox, and HIV.
1. A child who has passed the newborn hearing test should have their hearing tested regularly throughout their school years Hearing loss can develop at any time, yet for some reason, we deem the newborn hearing test a free pass to a lifetime of perfect hearing. This is, unfortunately, not the case and many children will go through school with an undetected hearing loss because they have not been retested since birth.
Lynell, a mother of 4, found herself in a state of shock when two of her children were found to have hearing loss. Harry, Lynell’s fourth child was diagnosed with ANSD (auditory neuropathy spectrum disorder), a hearing condition that makes up 10% of diagnoses for children with permanent hearing loss. Harry’s diagnosis prompted testing of all the children which led to the family discovering that son William, who showed no signs of hearing loss, also had a hearing issue.
Lauren’s daughter, Laila, wasn’t diagnosed with hearing loss until she was halfway through kindergarten. And it wasn’t due to a lack of testing. Unfortunately, multiple technicians advised Lauren that her daughter’s lack of response to sound was from a behavioural issue, not a hearing loss! It wasn’t until Laila’s first teacher and dance instructor insisted that something was wrong with her listening that Laila’s hearing loss was properly diagnosed.
