Deafness.
Deafness is a major community health problem to which doctors must remain alert. As many as 20 per cent of children are estimated to suffer a hearing loss sufficient to handicap development by the age of 10. Mild to moderate and fluctuating hearing loss is often difficult to detect in children and discovered only after development of a medical, language or educational problem.
