The WHO Academy’s mobile learning app was developed specifically for health workers and is designed to enable them to expand their life-saving skills to battle COVID-19. It delivers mobile access to a wealth of COVID-19 knowledge resources developed by WHO, including up-to-the-minute guidance, tools, training, and virtual workshops to support health workers in caring for patients infected by COVID-19 and in protecting themselves as they do their critical work. With content in seven languages – Arabic, Chinese, English, French, Portuguese, Russian and Spanish – the app focuses on providing health workers with critical, evidence-based information and tools to respond to the pandemic.
