World Hearing Day is held on 3 March each year to raise awareness on how to prevent deafness and hearing loss and promote ear and hearing care across the world. Each year, WHO decides the theme and develops a brochure on the topic based on the best available evidence as well as advocacy materials such as posters, banners, infographics and presentations, among others. These materials are shared with partners in government and civil society around the world as well as WHO colleagues across the Organization. At its headquarters in Geneva, WHO organizes an annual World Hearing Day seminar. In recent years, an increasing number of Member States and other partner agencies have joined World Hearing Day by hosting a range of activities and events in their countries. WHO invites all stakeholders to join this global initiative.
