The US Centers for Disease Control and Prevention (CDC) has created a chatbot that will talk to you about the symptoms of coronavirus, and whether or not you should seek medical assistance.   Called “Clara,” the chatbot was built on Microsoft’s “Healthcare Bot” and powered by the technology giant’s Azure cloud architecture. Clara will assess symptoms and risk factors for people who are concerned they might get infected, suggest what action they should take, and provide information for how to safely manage at home, Microsoft explained in a blog post.
