"The exposure risk level will allow PHAs to evaluate a potential exposure based on characteristics they have gathered about individuals who test positive and known information such as the approximate distance and duration. Based on this level, developers will also be able to alter their notification messaging to make it more useful and informative," both Apple and Google said in a joint statement.
