Conversational Agents (CAs) can be a proxy for disseminating information and providing support to the public, especially in times of crisis.CAs can scale to reach larger numbers of end-users than human operators, while they can offer information interactively and engagingly.In this work, we present Theano, a Greek-speaking virtual assistant for COVID-19.Theano presents users with COVID-19 statistics and facts and informs users about the best health practices as well as the latest COVID-19 related guidelines.Additionally, Theano provides support to end-users by helping them self-assess their symptoms and redirecting them to first-line health workers.The relevant, localized information that Theano provides, makes it a valuable tool for combating COVID-19 in Greece.Theano has already conversed with different users in more than 170 different conversations through a web interface as a chatbot and over the phone as a voice bot.
