This is a prospective observational study using a mobile study platform (app) that is designed for use on Android phones. Study participants will provide baseline demographic and medical information and report symptoms of respiratory infection on a weekly basis using the app. Participants will also report use of prevention techniques on the weekly survey. Mobility data will be collected passively using the sensors on the participant's smartphone, if the participant has granted the proper device permissions. The overall goals of the study are to track spread of coronavirus-like illness (CLI), inﬂuenza-like illness (ILI) and non-speciﬁc respiratory illness (NSRI) on a near-real time basis and identify speciﬁc behaviors associated with an increased or decreased risk of developing these conditions.
