Telehealth services have had a raised profile during the ongoing COVID-19 pandemic and their increased use has highlighted the need for standards that are inclusive of persons with disabilities and specific needs. The development of such standards for telehealth is important to help ensure accessible, effective and safe delivery of quality healthcare. This Recommendation is a WHO-ITU global standard for accessibility of telehealth services, which outlines some of the most common requirements on accessible telehealth services. More specifically, this Recommendation includes requirements on concrete accessibility features that healthcare providers and manufacturers of telehealth platforms need to ensure when delivering telehealth services. The standard can be used and implemented by governments, manufacturers of telehealth platforms and healthcare providers.
