World Hearing Day is a campaign held each year by Office of Prevention of Blindness and Deafness of the World Health Organization (WHO). Activities take place across the globe and an event is hosted at the World Health Organization on March 3rd. The campaign’s objective is to share information and promote actions towards the prevention of hearing loss and improved hearing care. The first event was held in 2007. Before 2016 it was known as International Ear Care Day. Each year, the WHO selects a theme, develops educational materials, and makes these freely available in several languages. It also coordinates and reports on events around the globe.
The theme of the campaign for World Hearing Day 2019 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. A study conducted in the United Kingdom indicate that only 20% of those who have a hearing problem seek treatment. A study performed in South Africa reported that individuals who experience hearing difficulties wait between 5 and 16 years to seek diagnosis and treatment. Part of the 2019 activities of the campaign is Wiki4WorldHearingDay2019. The purpose of this is to facilitate the contribution of hearing-related content into Wikipedia in several languages. Activities are reported in a Wikimedia dashboard.
A Meet-up took place with presentations by hearing researchers from the Hear in Cincinnati group, by hearing researchers from the National Institute for Occupational Safety and Health, the National Center on Birth Defects and Developmental Disabilities and National Center for Environmental Health, of the Centers for Disease Control and Prevention, by the Wikipedian-in-Residence from the National Institute for Occupational Safety and Health, and the Wikipedia Consultant for Cochrane.
