Around the world, one billion people live with disabilities. This report argues that these individuals are being left behind regarding health. Lack of access not only goes against the rights of people with disabilities under international law but also poses a challenge to achieving better health services for one billion people with disabilities, which is essential for achieving Universal Health Coverage (UHC) and Sustainable Development Goal 3. Most of these individuals are in low and middle-income countries and the poorest sections of society. People with disabilities encounter more obstacles in obtaining healthcare services and have less health coverage, leading to poorer health outcomes due to their higher healthcare needs.
