Twilio has partnered with Google and Apple to power Exposure Notifications, an open-source API framework for contact tracing. This system uses Bluetooth to anonymously track human proximity and notify people if they are exposed to COVID-19. The partnership aims to provide rapid notifications on the user's preferred channel, improving the efficiency of contact tracers in slowing the spread of the virus. By leveraging Twilio's Programmable Messaging API, public health authorities can text users deep links for the Exposure Notifications app with a unique code embedded, enabling them to easily take action and reducing the burden on call center agents. This scalable solution ensures that more people receive timely alerts and can take necessary precautions to prevent further exposure.
