Hear today, gone tomorrow?

Certain childhood illnesses, such as mumps, measles, meningitis and
rubella can also cause significant hearing loss. For this reason, it’s
important to get your child immunized. Also, ensure that your infant’s
hearing is checked. It’s possible to do
this within a week of birth. When hearing loss in children is identified
early, especially within six months of age, it can be treated and even
reversed, so that the child doesn’t develop speech impairments.
