On 3 rd March, Every year World Hearing Day is widely celebrated to raise awareness, to prevent deafness and to promote ear and hearing care across the planet. It was started by the WORLD HEALTH ORGANIZATION (WHO) in 2007 and was originally known as International Ear Care Day.
Theme 2020
WHO has decided the theme for 2020 is “Hearing for Life. Don’t let hearing loss limit you”.The selection of the theme by the World Health Organization expresses the key message that that timely and effective involvement can ensure that people with hearing loss are able to achieve their full potential. It recognizes that at all life stages good hearing health and communication connect us to the world. It highlights that appropriate and timely interventions can facilitate access to employment, communication, and education. There are insufficient hearing and ear care, across the globe. Unfortunately, across the globe, ear and hearing care are insufficient, and the WHO proclaims that all public health systems should include ear and hearing care.
