Tackling the Unseen Global Epidemic of Hearing Loss

As the globe observed World Hearing Day on March 3, the invisible epidemic of hearing loss came into sharp focus, an issue affecting millions worldwide, stirring a call for transformative action. The University of Pretoria, through its WHO Collaborating Centre for the Prevention of Deafness and Hearing Loss, is at the forefront of combating this pervasive problem. This year, under the theme, “Changing mindsets: ear and hearing care for all, let’s make it a reality,” a remarkable drive towards universal ear and hearing care is gaining momentum.

The staggering reality that over 80% of the global population struggles with unaddressed hearing loss, leading to an approximate $1 trillion (R19 trillion) economic burden annually, underscores the critical nature of this global health challenge. Yet, the response from the international community has been lacking, with many suffering from preventable or treatable conditions having no access to the care they need.

In the heart of South Africa, the Department of Speech-Language Pathology and Audiology at the University of Pretoria is pioneering efforts to overcome these challenges. With ground-breaking initiatives, such as the integration of innovative digital technologies, the department is reshaping the landscape of hearing care service delivery.

These technologies are game-changers, enabling community health workers in low-resource scenarios to conduct vital screenings and assessments. These initiatives mark significant strides towards delivering hearing aids and ensuring equitable health care access, especially in underserved communities. The Atteridgeville project, a collaboration with the hearX Foundation and the Clinton Health Access Initiative, serves as a beacon of hope, providing scalable solutions to affordable hearing care.

Encouraging early and wide-scale screening efforts, the university also led a World Hearing Day event in Atteridgeville, offering free hearing screenings and educational workshops. This event is not only a symbol of dedicated service to the local community but also reflects a broader commitment to global health.

The anticipated escalation of hearing impairments, with projections indicating 2.5 billion people may be affected by 2050, demands immediate and concerted efforts to provide comprehensive care. Interventions such as the University of Pretoria's revolutionary smartphone-based hearing tests, contribute significantly to early detection and offer scalable solutions that can be replicated throughout the globe.

Through partnerships, especially with the hearX Group, the center makes considerable strides in making these advanced hearing solutions widely accessible. Moreover, the WHO’s hearWHO smartphone application, supported by the university's collaborations, provides a rapid screening tool that has already facilitated close to 500 million tests in 191 countries.

However, diagnostics is only half the battle. The WHO is set to launch a guideline document in March for the provision of hearing aids to low-income communities, a critical resource inspired by the feasibility research from the University of Pretoria and the hearX Foundation. Such contributions are monumental steps towards bridging the service gap and alleviating the economic impacts of unaddressed hearing loss.

This World Hearing Day, the call resonates for global stakeholders to unite in integrating ear and hearing care into national health policies and ensure they are framed within person-centered approaches. The drive to deliver innovative solutions to those in most need encapsulates the spirit of this initiative.

Professor De Wet Swanepoel, celebrated for his expertise in audiology and his position as Research Director for the WHO Collaborating Centre for Prevention of Deafness and Hearing Loss, articulates the mission ahead. It's a vision of a future where ear and hearing care is universally accessible, enabling individuals to fulfill their potential, to hear, to be heard, and to flourish.
