There are no sure-fire ways to prevent hearing loss and deafness. Certain congenital conditions leave no room for prevention, especially if the mother isn’t aware she is carrying the virus. Likewise, it can be difficult to know you are suffering from a latent virus, as they show little to no symptoms. Getting tested regularly and staying on top of your health is the best preventative measure in these cases.
It is also important that you get yourself and your children vaccinated. While controversy has spread regarding this practice, even a single case of mumps or measles can result in acquired hearing loss. It is better to be safe than sorry in these situations, especially when your hearing is at risk.
Wider immunity should also be taken into account in these situations; even if your children recover from measles, an immunodeficient child might catch the virus and suffer serious health issues.
