There are around 447,600 people with disability in Cuba. A large number of people with disabilities in Cuba have an intellectual disability and about 3.2 percent have a severe disability. The government of Cuba has a medical model of disability in its approach to policies on people with disabilities. Another unique challenge that people with disabilities in the country face is due to the economic embargo of Cuba which has caused shortages in medical materials and assistive technology. The Constitution of Cuba has provisions for protecting the rights of people with disabilities and the country signed onto the Convention on the Rights of Persons with Disabilities in 2007.
