Covid-19 has had a devastating impact on individuals with intellectual disabilities. In this study, having an intellectual disability was the strongest independent risk factor for presenting with a Covid-19 diagnosis and the strongest independent risk factor other than age for Covid-19 mortality. Patients with intellectual disabilities and their caregivers should be prioritized for vaccination and health care services. While the needs of this population due to Covid-19 clearly require immediate attention, these results also reflect existing limitations of the health care system as they pertain to individuals with intellectual disabilities.
