The U.S. Centers for Disease Control and Prevention introduced a bot over the weekend to help people make decisions about what to do if they have potential symptoms of COVID-19. Called Clara, the “coronavirus self-checker” was created in partnership with CDC Foundation and Microsoft Azure’s Healthcare Bot service.

While COVID-19 has been declared a global pandemic by the World Health Organization, Clara is intended for use by people currently in the United States. According to the CDC, as of March 22, there were more than 15,200 cases in the United States, and 200 deaths.
