We Must Prioritise Early Hearing Care for Children

Long before a child says their first word, the brain is already listening. From around 28 weeks in the womb, the auditory system begins to stir, absorbing rhythm, tone, and the familiar cadence of a mother’s voice.

By birth, a newborn already knows that voice. And in the months that follow, every sound a child hears is: building the neural architecture that will one day underpin language, literacy, reasoning, and human connection. We talk a great deal about feeding children well in their earliest years. We talk far less about the equal importance of letting them hear well. In Kenya, and across much of sub-Saharan Africa, that gap in attention is costing children a future.

The scale of the challenge is significant. The World Health Organisation (WHO) estimates that more than 34 million children globally are living with deafness or hearing loss. Sub-Saharan Africa carries a disproportionate share of this burden, driven by preventable causes. In developing countries, including Kenya, permanent hearing loss in newborns is estimated at 3 to 6 per 1,000 live births, compared to 1 to 3 per 1,000 in high-income countries.

In Kenya, newborn screening is available but not mandatory across all public hospitals. The result is that most children are identified late, often only when they begin school and their struggles become impossible to explain away.

A child learns to speak by listening first, absorbing words, patterns, and meaning long before they can produce them. When hearing impairment goes undetected, we see consequences such as delayed speech, limited literacy, difficulty following instructions, and social withdrawal. Crucially, these signs are frequently misread as behavioural problems or slow development, rather than symptoms of an underlying hearing condition.

The research shows that children who receive interventions before six months old have markedly better language than those identified later. The evidence is so clear that the international standard, known as the 1-3-6 framework, calls for screening by one month, diagnosis by three months, and intervention in place by six months.

Unfortunately, that timeline is rarely met in Kenya. Late diagnosis remains the single biggest barrier to effective intervention. This late healthcare-seeking behaviour is also driven by myths and stigma surrounding hearing loss, making caregivers unlikely to seek treatment early.

To make matters worse, Kenya has a shortage of specialists for audiology. According to a survey covering 2009 to 2015, Kenya had just 0.015 audiologists per 100,000 people against the United Kingdom’s ratio of 4.1 per 100,000. Put differently, Kenya has less than 0.3 percent of the audiologist capacity of a comparable high-income country.

The consequences reach far beyond the clinical ones. Children who struggle to hear also struggle to participate in school and socialise. Hearing shapes social confidence and the ordinary rhythms of belonging. The emotional toll on families, the years of uncertainty, the misdiagnoses, the exhausting navigation of an under-resourced system, is real and lasting.

Therefore, the case for acting earlier is clear. Several specialist centres in Kenya have already demonstrated that high-quality paediatric audiological care is both possible and scalable here. The Kenyan government took a significant step forward with its National Ear and Hearing Care Strategy for 2023–2028, which explicitly prioritizes newborn hearing screening, expanded access to hearing technology, and growing the professional workforce.

Operationalising the strategy means embedding hearing screening into routine child wellness visits, training community health workers to recognise early signs, and normalising hearing assessment as a standard part of how we care for young children.

Parents are the first line of detection, and they need to know what to look for. A baby who does not startle at loud sounds, who does not turn towards a voice by four months, who is not babbling by nine months, these are signs worth acting on. When those milestones are shared consistently at every child wellness visit, the entire timeline of identification can shift.

Every child born in this country deserves not only the chance to hear the world clearly, but the opportunity, built on that hearing, to learn, and speak.
