The Office of Prevention of Blindness and Deafness of the World Health Organization (WHO) organizes an annual campaign called World Hearing Day, which is March 3rd. The campaign aims to share information and promote actions towards the prevention of hearing loss and improved hearing care. The theme of the 2019 campaign is “Check your hearing”. Data from both developed and developing countries indicate that a significant part of the burden associated with hearing loss comes from unaddressed hearing difficulties.
