Shingles is caused by the varicella-zoster virus â the same virus that causes chickenpox. Anyone who's had chickenpox may develop shingles. After you recover from chickenpox, the virus can enter your nervous system and lie dormant for years.
Hearing loss, also known as hearing impairment, is a partial or total inability to hear. A deaf person has little to no hearing. Hearing loss may occur in one or both ears. In children hearing problems can affect the ability to learn spoken language and in adults it can cause work related difficulties.
Hearing loss is a common problem that often develops with age or is caused by repeated exposure to loud noises. Action on Hearing Loss estimates that there are more than 10 million (about 1 in 6) people in the UK with some degree of hearing impairment or deafness.
