This brief summarises lessons learned about how COVID-19 prevention programmes can be inclusive of people with disabilities, older adults, and caregivers. The brief covers: a) an overview of why inclusion is critical to COVID-19 response programming, b) a summary of lessons and key actions to strengthen inclusion planning, implementation actions and monitoring, and c) a checklist to assess inclusion in your programming. The brief is primarily oriented towards organisations working to improve hygiene related behaviours such as handwashing with soap, mask use, surface cleaning and physical distancing. This brief is based on the insights that have been gained through programming funded by the Hygiene and Behaviour Change Coalition (HBCC) and/or supported by the COVID-19 Hygiene Hub.
