Rare Disease Day 2026 highlights global inequities and amplifies youth voices in call for lasting change
On 28 February 2026, Rare Disease Day will once again bring together millions of people worldwide to spotlight the realities faced by those living with rare diseases
and to call for more equitable healthcare, research and social inclusion.
There are more than 6,000 identified rare diseases,
together impacting an estimated 300 million people worldwide
– between 3.5 and 5.9% of the global population.
Seventy-two per cent of rare diseases are genetic,
and around 70% present in childhood.
Many are chronic, progressive and life-limiting.
One in five cancers is classified as rare.
Despite this scale, people living with rare diseases frequently experience years of delayed diagnosis,
limited or no treatment options, fragmented care,
and significant social and economic barriers.
Rare Disease Day exists to address these inequities.
Since its launch in 2008, when events were held in just 18 countries,
the campaign has grown into a global movement now observed in more than 100 countries.
Coordinated by national alliances and patient organisations across 77 countries,
it creates a shared moment each year to make visible challenges that often remain overlooked in health and social care systems, and policy debates.
