The document proposes a tool called RingAround to help manage future Ebola outbreaks. RingAround consists of cheap Bluetooth-enabled mood rings that can detect the wearer's temperature. If a fever is detected, the ring would notify the wearer's phone which would automatically send text messages to the wearer's contacts and local CDC to alert them and help isolate the potentially infected person. The rings would also continuously send health updates to the CDC to help manage the person's condition and send advice. The tool aims to leverage the widespread mobile phone and Bluetooth usage in West Africa to help curb the spread of Ebola.
