WHY DOES CMV CAUSE HEARING LOSS?

Cytomegalovirus (CMV) is a common virus that can cause a variety of health problems, including hearing loss. CMV is spread through contact with bodily fluids, such as saliva, urine, or blood. It can also be spread from a pregnant woman to her unborn child. In most cases, CMV is a mild infection that does not cause any symptoms. However, in some people, CMV can cause serious problems, including hearing loss, vision loss, and intellectual disability.

How Does CMV Cause Hearing Loss?

CMV can cause hearing loss in several ways. One way is by directly damaging the inner ear, which is responsible for hearing. CMV can also cause hearing loss by damaging the nerves that connect the inner ear to the brain. Additionally, CMV can cause inflammation in the inner ear, which can also lead to hearing loss.

Who Is at Risk for CMV-Related Hearing Loss?

Anyone can get CMV, but some people are at higher risk for CMV-related hearing loss. These include:

• Unborn babies: CMV can be spread from a pregnant woman to her unborn child. Babies who are born with CMV are at risk for hearing loss and other health problems.
• Infants and young children: CMV is a common infection in infants and young children. While most children who get CMV do not have any symptoms, some may develop hearing loss or other health problems.
• People with weakened immune systems: People with weakened immune systems, such as those with HIV/AIDS or cancer, are at higher risk for CMV infection and CMV-related hearing loss.

What Are the Symptoms of CMV-Related Hearing Loss?

The symptoms of CMV-related hearing loss can vary depending on the severity of the hearing loss. Some people may experience mild hearing loss, while others may have severe hearing loss or even deafness. Symptoms of CMV-related hearing loss can include:

• Difficulty hearing speech and other sounds
• Tinnitus (ringing in the ears)
• Ear pain
• Dizziness or balance problems
• Speech problems

How Is CMV-Related Hearing Loss Diagnosed?

CMV-related hearing loss is diagnosed with a hearing test. A hearing test can measure the severity of the hearing loss and help determine the cause of the hearing loss. Blood tests can also be done to check for CMV infection.

How Is CMV-Related Hearing Loss Treated?

There is no cure for CMV-related hearing loss. However, there are treatments that can help improve hearing and manage the symptoms of hearing loss. These treatments may include:

• Hearing aids: Hearing aids can amplify sound and make it easier to hear.
• Cochlear implants: Cochlear implants are surgically implanted devices that can help people hear.
• Assistive listening devices: Assistive listening devices can help people hear better in certain situations, such as in noisy environments.

How Can CMV-Related Hearing Loss Be Prevented?

There is no sure way to prevent CMV infection. However, there are things that can be done to reduce the risk of CMV infection, including:

• Washing hands frequently with soap and water
• Avoiding contact with bodily fluids, such as saliva, urine, or blood
• Using condoms during sex
• Getting vaccinated against CMV (the CMV vaccine is currently only available in some countries)
