Background: Individuals with neurodevelopmental disorders (NDD) are facing unprecedented challenges due to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Congregate living, and conditions associated with NDD place increased challenges during infectious disease outbreaks and there is a need to understand evidence-based response procedures. The aim was to (1) map and synthesize literature regarding emergency response protocol in supported living environments for individuals with NDD and (2) identify gaps in the literature of response protocols in supported living environments for individuals with NDD. Methods: A scoping review was conducted to understand the published literature on emergency response across supported living environments for individuals with NDD during emergency situations and infectious disease outbreaks. Results: The ten studies included in the review detailed protocols including treatment, testing, isolation, surveillance, improved cleaning, use of protective equipment, and contact with public health professionals. The environment of supported living settings, and symptoms associated with NDD impacted the spread and severity of disease. Conclusion: The research findings highlight the susceptibility, severity and impact of infectious disease outbreaks for individuals with NDD in supported living environments. This research will promote the establishment and development of appropriate care and response during emergency situations in supported living environments.
