Immunity to Covid-19: March 2023 update
How do our bodies defend against Covid-19? Read how immune responses differ across people, variants, reinfection, vaccination, and current immunisation strategies.

Disability occurs in many different forms. An invisible disability, or non-visible disability, is an impairment or health condition that is not immediately obvious. This POSTnote provides an overview of invisible disability in the UK. It outlines types of invisible disabilities and relevant legislation and policy. It also discusses the experiences of adults with invisible disabilities, and strategies aimed at increasing access and inclusion for adults with invisible disabilities, focusing on employment, and higher and further education.

It is estimated that 70-80% of disabilities are invisible. There are a wide range of impairments or conditions not necessarily visible to others, which are not limited to, but include: mental health conditions; autism and other neurodivergences, cognitive impairments; hearing, vision and speech impairments; and energy-limiting conditions (such as fibromyalgia). Because an invisible disability is not outwardly observable, they may face disregard or disbelief of their disability. They may experience difficulties participating in work and education and in accessing the services and support they need. Disabled people can have both non-visible and visible impairments, or impairments that are only visible in certain circumstances or settings.
POSTnotes are based on literature reviews and interviews with a range of stakeholders and are externally peer-reviewed. POST would like to thank interviewees and peer reviewers for kindly giving up their time during the preparation of this briefing, including:
