National Disease Literacy Month
September 1 - September 30
About National Disease Literacy Month
National Disease Literacy Month takes place throughout September each year and encourages people, particularly children living with chronic conditions, to better understand their diagnosis and the care it requires. The observance promotes the idea that when patients understand their illness, they make better decisions, follow treatment more reliably, and experience improved outcomes. In 2026 it runs across the whole of September, from Tuesday, 1 September to Wednesday, 30 September.
What is National Disease Literacy Month?
National Disease Literacy Month is an annual health observance focused on improving disease literacy, which is the degree to which individuals understand their diagnosis and the treatments and services available to them. While the campaign is relevant to patients of all ages, it places particular emphasis on children and their understanding of the conditions they live with day to day. The month was established by the Registrar at National Day Calendar in 2019 and is observed each September. It complements the broader push for health literacy by narrowing the focus to the specific, practical knowledge a person needs to manage a named condition.
When is National Disease Literacy Month?
National Disease Literacy Month is observed every September. In 2026 it begins on Tuesday, 1 September and concludes on Wednesday, 30 September. The dates are fixed: the observance always covers the full calendar month of September, so there is no need to check for a shifting date each year. This makes it easy for schools, clinics, paediatric units, and patient organisations to plan activities well in advance.
Why National Disease Literacy Month Matters
Understanding a diagnosis is not a luxury, it is a practical requirement for staying well. When patients do not grasp what their condition is or why their treatment matters, they are more likely to skip medications, miss appointments, and misread warning signs. The consequences are real: chronic conditions are common in childhood, with research in Academic Pediatrics estimating that more than half of American children have a diagnosed chronic condition, while millions more live with conditions that are undiagnosed.
The link between literacy and health is well evidenced. Studies of children with asthma, for example, show that lower reading ability is associated with a poorer understanding of triggers and the actions needed to stay healthy. A systematic review of paediatric patients with chronic disease found that health literacy shapes health behaviour, use of health services, outcomes, and a young person’s sense of empowerment over their own care. National Disease Literacy Month draws attention to this gap and encourages families, educators, and clinicians to close it.
How to Get Involved in National Disease Literacy Month
There are many practical ways to support the aims of the month, whether you are a parent, teacher, healthcare professional, or someone managing a condition of your own.
- Learn your own diagnosis in plain language – Ask your doctor or nurse to explain your condition in everyday terms, and request written or visual materials you can refer back to at home.
- Help a child understand their condition – Use age-appropriate books, diagrams, or apps to explain what is happening in a young person’s body and why their treatment helps.
- Prepare questions before appointments – Write down what you want to know in advance so that medical visits become a two-way conversation rather than a rushed handover of instructions.
- Use the teach-back method – After a clinician explains something, repeat it back in your own words to confirm you have understood it correctly.
- Share trustworthy resources – Point friends and family towards reputable patient organisations and medical bodies rather than unverified social media posts.
- Support literacy in your community – Volunteer with reading programmes or patient education initiatives, since general literacy and health literacy are closely linked.
- Encourage schools to take part – Suggest that teachers include simple lessons on understanding the body, illness, and medicine, especially for pupils living with chronic conditions.
- Champion clear communication at work – If you work in healthcare, review your patient materials for jargon and rewrite them in language a worried parent or anxious teenager can follow.
History of National Disease Literacy Month
National Disease Literacy Month is a relatively recent addition to the health calendar. It was proclaimed by the Registrar at National Day Calendar in 2019 and has been observed annually each September ever since. The campaign emerged from a growing recognition that general public health messaging, while valuable, does not always translate into the specific, actionable understanding a patient needs once they receive a particular diagnosis.
From the outset, the observance has carried a strong focus on children. The reasoning is straightforward: a child who does not understand their condition is far less likely to take ownership of their care, and that pattern can persist into adolescence and adulthood, when young people are expected to manage their own medication and appointments. By concentrating attention on this group, the month aims to build understanding early, when habits and confidence are still forming.
Since its establishment, the month has been picked up by patient advocacy groups, non-profit organisations, and writers seeking to highlight the importance of understanding illness. It sits alongside the longer-running Health Literacy Month, observed each October, which was founded in 1999 by educator and occupational therapist Helen Osborne. Where Health Literacy Month addresses the broad ability to find and use health information, National Disease Literacy Month sharpens the lens onto understanding a specific condition.
Noteworthy Facts About National Disease Literacy Month
- The observance was created by National Day Calendar’s Registrar in 2019 and is marked every September.
- Research in Academic Pediatrics has estimated that at least 54% of American children have a diagnosed chronic condition.
- For every child diagnosed with a chronic illness, many more remain undiagnosed, leaving millions of young people without a clear understanding of their own health.
- Studies show general literacy and health literacy are highly correlated, meaning reading ability directly affects how well a child can understand their illness.
- A systematic review of paediatric patients with chronic disease linked higher health literacy to better health behaviour, service use, outcomes, and patient empowerment.
